Cast Of The Movie Knives Out

The new murder mystery movie Knives Out is filled with famous actors many audiences already know and love. But there's one face in the cast who might not be as familiar to fans. For now, at least. In Knives Out, Johnson will play Richard Drysdale, the husband to Jamie Lee Curtis' Linda. Recently, the Tin Cup actor went on The Deep Cut podcast and raved about his experience on set. Knives Out features a massive ensemble cast including Daniel Craig in Knives Out, Christopher Plummer, Chris Evans, Ana De Armas, Jamie Lee Curtis, Don Johnson, Michael Shannon, Toni Collette.

The new murder mystery movie Knives Out is filled with famous actors many audiences already know and love. But there's one face in the cast who might not be as familiar to fans... for now, at least. Ana de Armas, who plays Marta Cabrera in Knives Out, is a total standout in the film, and has audiences excited to see more of her (which they will).

In Knives Out, De Armas' Marta is the protagonist and caretaker of the famous and wealthy author Harlan Thrombey (Christopher Plummer). When Harlan dies suddenly and gruesomely, Marta is forced to deal with his greedy extended family — and a big secret of her own — while a team of detectives investigate the whole situation. Even among the big, stacked cast, which includes Daniel Craig, Jamie Lee Curtis, Katherine Langford, Chris Evans, Toni Collette, and more, the relative newcomer stands out in her dynamic role.

With Knives Out as well as another major upcoming blockbuster, it's been a busy time for de Armas. 'I’m not complaining, because it’s taken me a long time to get here, and I’m living my dream,” de Armas told the Los Angeles Times. 'This is exactly what I want to be and what I want to do — but gosh, I’m tired. I feel like I repeat that a lot. But I’m tired. I think 2020 will be the year for me to sleep a little bit more.”

The actor might be going to sleep in 2020, but that'll be the year audiences will definitely be seeing a lot more of her. Here are the key facts you need to know to get ready for what's shaping up to be the Year of de Armas:

1. When She Arrived In Hollywood, She Didn't Speak English

De Armas was born in a small town just outside Havana, Cuba, in 1988. At age 18, she became a TV star in Spain, and she then moved to the U.S. in 2014 to take on Hollywood. She didn't speak English when she arrived, so she did months of intensive language studies before landing roles in movies like War Dogs and Blade Runner 2049.

2. She Initially Turned Down 'Knives Out'

The character description for de Armas' character Marta simply said she was a 'pretty Latina caretaker,' and, unhappy with that description, she decided she didn't want to be involved with the project. She explained to The Hollywood Reporter:

Getting an email that described the character like that — without any more information or a script attached because it was high-profile and secret — just really didn’t speak to me. So, because of the character description, my imagination immediately went to a portrayal that was not necessarily very positive or exciting in relation to Latin culture.

Luckily, she learned Marta was much more nuanced. She said to THR, 'When I finally read the script, I realized that the description didn’t fit at all because Marta is so much more than that.”

3. She's Co-Starring In A Film With Ben Affleck

De Armas and Affleck are playing a wife-andohusband duo in the upcoming thriller Deep Water. The movie is expected to come out toward the end of 2020.

4. She's The Next 'Bond Girl'

James Bond is known for having a badass woman by his side in each movie, and de Armas is going to play the part in the upcoming No Time to Kill. Unlike some Bond films of the past, however, the Los Angeles Times reports there will be 'a very different dynamic' between 007 and his co-star this time around.

Knives Out is in theaters now.

By/Nov. 18, 2019 6:18 pm EDT/Updated: Oct. 19, 2020 12:01 pm EDT

After directing critically-acclaimed films like Brick, Looper, and Star Wars: The Last Jedi, Rian Johnson turned his attention to the murder mystery genre, giving us the star-studded Knives Out. The movie currently sits at a lofty 97 percent on Rotten Tomatoes, which is quite the accolade, and Vox's Alissa Wilkinson describes the flick as 'a delightful Agatha Christie-style whodunnit made for 2019 America.'

Perhaps the film's most obvious asset is its wildly talented cast, consisting of former superheroes, super villains, super spies, a few legendary Hollywood superstars, and everything in between. But while watching a murder mystery movie, the only thing you want to be trying to solve is who the killer is, not who the actor or actress playing the killer is and what other films you've seen them in before. So, before you watch the movie, here's a handy who's who for Rian Johnson's whodunnit, Knives Out.

Daniel Craig steals the show as Detective Benoit Blanc

Unless you've been living under a rock for the past decade, chances are good that you're familiar with Daniel Craig and his prestigious body of work. The English actor's breakout role was that of the iconic 00 Agent, James Bond, in 2006's Casino Royale. It was a role that, thanks to multiple sequels (four to date), landed him on Forbes' World's Highest Paid Actors list in 2015. However, the handsome Brit is far from a one-trick pony. Over the years, Craig has excelled in a vast array of genres, ranging from dramas like 2002's Oscar-winning Road to Perdition to comedies like 2017's Logan Lucky. He's certainly come a long way from playing a love-struck stableboy in Disney's mid-'90s medieval stinker, A Kid in King Arthur's Court.

In Knives Out, Craig plays Benoit Blanc, a private detective brought on to investigate the apparent suicide of a famous crime novelist. Craig was actually the first actor to sign on to the project, and he was apparently flattered to have been offered the part. As he explained to Cinema Blend, 'I hadn't read something like that (screenplay) before, and I was just over the moon that he (Johnson) offered it to me.' With a lead like Craig, it's no mystery why so many critics are crazy about Knives Out.

Chris Evans stars as Ransom Drysdale

Agatha Christie lovers ... assemble! Although the MCU's Captain America obviously won't be making an appearance in Johnson's murder mystery, Chris Evans, who's played the star-spangled Avenger several times since 2011's Captain America: The First Avenger, will be. The Boston-bred hunk has flexed his dramatic ability in films like Before We Go and Gifted, but not as often as he's flexed his impressive physical physique in action flicks like Push, The Losers, and Scott Pilgrim vs. the World.

With an apparent affinity for playing 'the good guy,' Evans has played not one but two different superheroes, first starring as the Human Torch in the Fantastic Four franchise. His role of Ransom Drysdale in Knives Out, however, will be quite the opposite. Speaking with Entertainment Weekly, Evans explained, 'I'm usually tasked with playing guys who are a little more noble, and this guy is a little bit more vile. It's fun.'

Toni Collette is Joni Thrombey in Knives Out

Although it didn't exactly light up the box office, 1992's The Efficiency Expert, starring acting legends like Anthony Hopkins, Russell Crowe, and even a young Ben Mendelsohn, marked the film debut of Toni Collette. In the decades to come, the Australian actress would enjoy a highly successful career, most evidenced by her massive award-season love.

Cast Of The Movie Knives Out

In 2009, she was cast as the lead role (or, perhaps more appropriately, lead roles) in Showtime's United States of Tara. As Tara, a mother coping with dissociative identity disorder, Collette earned wins at both the Golden Globes and the Emmys. On the big screen, the actress has excelled in dramatic comedies like Little Miss Sunshine and About a Boy. However, she's perhaps most recognized for her work in a pair of iconic horror flicks: 1999's unforgettably twisty The Sixth Sense and 2018's disturbingly dark Hereditary.

In Knives Out, the decorated actress plays Joni Thrombey, a 'lifestyle guru' (drawing obvious inspiration from Gwyneth Paltrow and her company, Goop) and daughter-in-law of murder victim Harlan Thrombey. When speaking to Deadline, Collette showered the murder mystery's script with praise, saying, 'It was all in the writing. In reading it, it just kept opening up and changing, and it was so swift, and so smooth, and so surprising.'

Katherine Langford appears as Meg Thrombey

What Katherine Langford's filmography lacks in quantity, it makes up for in quality. At the ripe age of 20, the young Australian actress landed the role of ill-fated high school student Hannah Baker in the Netflix smash series 13 Reasons Why. Langford stole the show as Hannah, even earning a Golden Globe nominee for her performance. Her newfound stardom landed her parts in two movies in 2018, The Misguided and Love, Simon.

Although she'd previously worked with some fairly big names, such as Jennifer Garner and Josh Duhamel, Langford was admittedly quite starstruck when seeing her Knives Out co-stars in action. Talking with Yahoo! TV, Langford said, 'I get so in awe of everyone. ... I've watched all of these people.' While sharing the screen with A-listers like Daniel Craig and Chris Evans must've been incredible, the young starlet, who plays Meg Thrombey in the whodunnit, went on to specifically give praise to her fellow Aussie actress. 'Toni Collette, who plays my mom in this film, she's a legend in her own right. To work a lot with her is amazing, and to work with everyone is amazing.'

Knives Out features Michael Shannon as Walt Thrombey

Michael Shannon has quietly evolved into one of the most well-rounded actors in Hollywood. The two-time Oscar-nominated actor has appeared in a plethora of movies over the past 20 years, ranging from action blockbusters to dramatic thrillers. The first movie he ever popped up in was actually 1993's classic comedy, Groundhog Day, but he's really made much more of a name for himself in serious roles, such as the mentally disturbed John Givings in 2008's Revolutionary Road.

You might also recognize Shannon from parts he played in films throughout the 2000s, including Vanilla Sky, 8 Mile, and Bad Boys II. He's given notable performances for director Jeff Nichols in movies like Take Shelter andMidnight Special, and on HBO's Boardwalk Empire, he portrayed Nelson Van Alden, an agent for the Bureau of Prohibition. He even went toe-to-toe with Henry Cavill's Superman as General Zod in 2013's Man of Steel.

In Knives Out, the Kentucky-bred actor plays Walt Thrombey, the new CEO of his father's publishing house. In an interview with Slash Film, Shannon mentioned how great it was to work with Rian Johnson on the set, saying, 'I had a blast, man, that was so much fun. ... Also, Rian is a super, super sweet guy.' Having a sweet boss must be a major plus on a movie production.

Ana de Armas is playing Marta Cabrera

Although her official acting debut came in a Spanish film in 2006, Ana de Armas' Hollywood career really started in 2015, starring alongside Keanu Reeves as Bell in the dark thriller Knock Knock. After that, she played Miles Teller's girlfriend, Iz, in War Dogs, and then the holographic Joi in the trippy Blade Runner 2049.

Although she's starring alongside Daniel Craig in 2020's new Bond film, No Time to Die, the gorgeous Cuban starlet first shared the screen with him in Knives Out. As Marta Cabrera, the recently deceased Harlan Thrombey's live-in nurse, de Armas is one of the prime murder suspects. But while de Armas admittedly had a wonderful experience on set, shooting in Boston had one particular downside. As she explained, 'It was my first time in Boston. It was freezing, for a Cuban especially.' The actress may have been cold, but is she actually Knives Out's cold-blooded killer?

Jamie Lee Curtis is showing up as Linda Drysdale

Jamie Lee Curtis is truly an American treasure. The California-raised actress has appeared in so many films and TV shows through the years that it's hard to keep track of them all. If you're a horror fan, you probably know her best as Laurie Strode in John Carpenter's Halloween franchise. However, she's so much more than a scream queen. Curtis has starred in action classics like True Lies, kids' movies like Freaky Friday, and a slew of feel-good comedies, including My Girl and You Again.

With an ensemble cast as star-studded as that of Knives Out, it's hard to imagine any one person really standing out. However, when speaking to Entertainment Tonight, director Rian Johnson had a clear cut MVP: Jamie Lee Curtis as Linda Drysdale. The award-winning actress would show up early to set every day, even when she wasn't scheduled to be in the scene. 'I was like, 'Jamie Lee Curtis is here! Film her!' She got into scenes she wasn't even supposed to be in — just because she was there!' Talk about being in the right place at the right time!

Knives Out stars Don Johnson as Richard Drysdale

Detective James Crockett has certainly aged well. Don Johnson, who won a Golden Globe for his portrayal of the snazzily dressed, undercover detective in the classic '80s TV series Miami Vice, remains a big name in Hollywood, still popping up in movies while well into his 60s. Since 2010, the Missouri-born actor has starred in a few Western-themed action flicks, such as Machete and Django Unchained, as well as a couple of romantic comedies, including The Other Woman and Book Club. He's also been an apparent go-to-guy for HBO, starring in both Eastbound & Down as Kenny Powers' father, Eduardo Sanchez, and more recently as police sheriff Judd Crawford in Watchmen.

In Knives Out, Johnson will play Richard Drysdale, the husband to Jamie Lee Curtis' Linda. Recently, the Tin Cup actor went on The Deep Cut podcast and raved about his experience on set. He also disclosed that he was able to see an early screening of the film, and it blew him away. 'Actually it's so good that I am super proud of it.'

Christopher Plummer is playing Harlan Thrombey

Canadian actor Christopher Plummer solidified his status as an acting great by taking home an Oscar for his portrayal of Hal, a closeted gay man, in 2010's Beginners. With acting credits dating back to the 1950s, Plummer has enjoyed an exceptionally long and fruitful career, and it's still going strong. In 2001, he played Dr. Rosen in the Oscar-winning A Beautiful Mind, and in 2017, he played J. Paul Getty in the Oscar-nominated All the Money in the World. He certainly has a knack of being attached to prestigious projects, going all the way back to The Sound of Music.

In Knives Out, Plummer is playing Harlan Thrombey, a famous mystery author who's found dead. In the film, Harlan is tended to by his live-in nurse, Marta, played by Ana de Armas, and it sounds as though the two performers really developed a strong relationship on set. When The Hollywood Reporter caught up with Plummer at TIFF, the Barrymore actor was asked, of all the people in attendance at the film festival, who he would most like to be stuck in an elevator with. And the man replied, 'Apart from my wife, I think Marta (de Armas), our beautiful lady who is such a good actress. ... That would be very pleasant.' It's safe to assume that most guys would agree with Plummer's response.

Jaeden Martell is taking on the role of Jacob Thrombey

He may look young, but don't make the mistake of thinking Jaeden Martell isn't already the man. He's not even 20 years old yet, and he's already starred in a couple of major movies and TV shows. Before playing Bill Denbrough, the leader of the Losers' Club, in 2017's It, the young star shined alongside Bill Murray in 2014's St. Vincent, and he also played Johnny Masters in Showtime's often raunchy drama, Masters of Sex. (He was also the title character in The Book of Henry ... although the less said about that particular film, the better.)

Cast Of The Movie Knives Out Full

In Knives Out, Martell plays Jacob Thrombey, the internet-trolling son of Michael Shannon's Walt. Interestingly enough, this isn't the first time Martell and Shannon played father and son on the big screen. In 2016, the duo co-starred in the thrilling sci-fi mystery, Midnight Special. It must be nice to have a father figure like Shannon on set.

Movie Knives Out Cast

Lakeith Stanfield will try to solve the mystery as Detective Lieutenant Elliot

Life has been especially good for Lakeith Stanfield over the past ten years. The California-raised actor's first big break was getting cast as Marcus in Short Term 12, alongside Brie Larson. He then was cast as Jimmie Lee Jackson in 2014's Oscar-winning Martin Luther King Jr. biopic, Selma. Since then, his career has really caught fire. Although he's appeared in popular films like Get Out, Sorry to Bother You, and Netflix's Death Note, perhaps his most recognizable role is that of the philosophical stoner Darius in Donald Glover's comedic drama Atlanta. Then again, he also portrayed a young Snoop Dogg in 2015's Straight Outta Compton, so you be the judge.

For Knives Out, Stanfield is playing Lieutenant Elliot, a detective investigating Harlan Thrombey's death who initially believes it to be a suicide. However, as more clues begin to surface, his character starts to suspect something more sinister is afoot. The award-winning actor will, much like the audience, try to solve Rian Johnson's whodunnit.

Cast Of The Movie Knives Out Netflix

Riki Lindhome will be appearing in Knives Out as Donna Thrombey

Who Is The Cast Of Movie Knives Out

Riki Lindhome is undoubtedly one funny chick, but she doesn't limit herself to just comedy. Although she and fellow comedian Kate Micucci make up the comedy duo Garfunkel & Oates, Lindhome's first on-screen part was as Mardell Fitzgerald in Clint Eastwood's Oscar-winning Million Dollar Baby. After that, she landed the recurring role of Juliet in the sixth season of the Gilmore Girls, as well as parts in films like My Best Friend's Girl, Changeling, and The Last House on the Left.

Cast Of The Movie Knives Out Cast

In Johnson's murder mystery, the Emmy-nominated actress is playing Donna Thrombey, the wife of Michael Shannon's Walt and mother of Jaeden Martell's Jacob. In addition to working with some major movie stars, Lindhome has certainly enjoyed the movie's many twists and turns, telling Yahoo! Entertainment, 'You see a lot of movies, and they'll have like one big twist. With Knives Out, there's just one after the other after the other. ... By the end everything's woven together in this sort of masterful puzzle.' Count us in!

People now are changing their smartphone quite frequently as new flagship mode comes out almost every month. And it is convenient to sell the used phone online. However, you might not be aware of the fact that the default data wiping tool that came along with your phone, might not be enough for permanent deletion of personal data on your device. But, if you are thinking about wiping out the data from your device completely due to some reason, you can follow this tutorial and here are some details to help you in this regard.

From a study conducted by the Security Software seller called Avast, it was found that the factory reset option shipped with Android phone in default will not be effective in complete eradication of personal data. This holds true, particularly when you own older versions of Android phone. Even though Avast and many other companies offer tools that will help with data deletion, there are other alternatives that you can choose to safeguard your personal data when you have to perform a factory reset.

Guide: How to Wipe Android Phone or Tablet

Step 1 Encrypt Data on Your Phone

Experts recommend that you will have to encrypt your phone or tablet with Android operating system before you are actually ready to completely get rid of the data from your device. This process will jumble your data on the phone or tablet and even if the content is not wiped fully, a special key will be needed to read the data.

To carry out this process, enter settings and then click on the security tab. Then, you will have to select the encrypt phone option. However, this option might be present in different places in different devices.

Step 2 Perform a Factory Reset

Best Memory Cleaner For Android

Secondly, you will have to perform a factory reset to wipe out the data in your phone completely. In the case of stock Android, you will have to go to the backup and reset option to complete this process. This particular option can be found under the settings menu of your Android tablet or phone. The thing to remember here is that factory reset will erase all the data in your device. So, it is recommended to take a backup of important data and applications before you click on this particular option.

Step 3 Load Dummy Data

Even though the above-mentioned two steps will be enough for most android users, but there is an extra step you can take. This step will make sure that you will get another layer of protection to your device when you are in the process of getting rid of your crucial data. During this step, you can try loading some useless contacts and photos on your device. Why this should be done? This will overwrite new data to existing data, making it hard to be recovered by special data recovery software.

Guide: How to Wipe Your Android Completely with 1-Click

If you found the above tutorial is too complicated or don't want waste valuable time on this, then you can go through the following tutorial instead. There are some very smarter developers out there that they made some very good software at easing data on Android device. And Phone Transfer is the one of the best among them. It utilizes the military-standard algorithms to wipe the device. Even federal agents can't get a single piece of data from your device.

Tips: for iPhone users, you can use Safewiper iPhone Eraser instead. It has several options to completely erase private data on iPhone.

First download and install this program on your computer. On startup, you will see 4 options listed on main screen. Select 'Erase All Data '.

Connect your phone to computer with USB cable. A minute later, the device should be recognized by this program and its name will be displayed on the main screen too. Type 'delete' in the blank box to confirm you are sure to erase this phone. Finally, click 'Erase' to permanently wipe this device. All the data stored in memory and external storage will be deleted completely. And there is no chance to recover them from now.

Citrix primarily focuses on Thin Client and Virtualization technologies but they have also expanded into other areas including networking technologies.

Thin Client and Virtualization leader

Thin Client technology also known as Server Based Computing (SBC) has made Citrix Virtual Apps a market leader, but what is Thin Client technology?

Before lifting the lid on how Thin Client technology works, let's look at another technology which many people use in their day to day lives. This technology focuses on searching the world wide web (Internet).

The user uses a search engine such as the likes of Google, Yahoo, Bing or one of the other many search engines. The user enters some words into Google's search box and when the 'search' key is pressed, the results appear within a few seconds.

This search information is not stored on the user's computer, that is, there isn't a massive store of all the websites Google knows about hiding in the user's computer.

In reality what happens is when the user presses 'Search', their search request is sent to a data centre, where a series of very powerful computers search their data banks for the relevant information that matches the users search request.

Once this information is found, it is sent back to the user's computer, where it is displayed as the search results, as shown by the screenshot below.

The grunt of the operation, that is, where all the processing of information is carried out, is in the data centre and not on the user's computer. It's the data centre computers which sift through the billions of information files in its data banks to determine what closely meets the user's request for information.

Once the information is found, it is sent back to the user's computer where the user's web browser (such as Microsoft Internet Explorer, Mozilla Firefox to Google Chrome) present that information as a series of results.

In the Google search example it is important to understand the importance of where the information processing takes place. As this is paramount to how Thin Client technology also works.

In the Thin Client world, the processing of information takes place away from the user's computer, typically on a powerful set of computers in a data centre, just like the search engine example earlier.

Instead of web pages being sent to the user's computer, the thin client technology works with applications and the presentation of these applications. So an application such as a word processor in thin client technology doesn't exist on the user's computer.

The word processor exists on a powerful set of computers in the data centre from where all the processing is done. The thin client technology represents the word processor to the user's computer, as though it was actually installed on their computer.

The first screenshot below, shows an application running remotely which for all intents and purposes looks like it is actually installed and running on the computer, when in fact it is not.

At the bottom right of this screenshot there is an icon circled in red, which is the Citrix plug-in icon and this when clicked, will show the application is actually running remotely.

Later on this section, the steps taken to connect to the application shown in this screenshot, will be shown.

The thin client technology captures the keyboard strokes the user makes and their mouse movements from their mouse attached to their computer, sending these to the powerful set of computers at a data centre to process.

The powerful computers at the data centre apply the users captured keyboard strokes and mouse movements to the word processor application and the resulting change in how the applications user interface changes, that is how what the user would see on their screen changes, is sent back to the user's computer.

At the user's computer, the thin client software creates an image of how the changes made to the word processor looks. The screenshot below, provides an overview of how the changes are propagated.

This is all done in milliseconds and gives the impression that the word processing software is actually installed and running on the user's computer when it is in fact running on another computer far, far away.

Still not sure of how thin client technology works? Well let's access an application remotely from a powerful computer in a data centre for real.

Citrix tech how it works

To reiterate what has been covered so far, in the world of Thin Client technologies like Citrix Virtual Apps, use a computer to remote control an application installed on another computer.

The other computer does all the grunt of processing the application and dealing with the users inputs that is, changes in their mouse movements along with keyboard strokes and dealing with outputs, that is, changes to the applications user interface, which is, how the application is presented to the user.

So there could have a computer in New York City which has word processing software installed and a user could connect to this computer say from a computer in London and use the word processor without having the word processing software actually installed (resident) on our computer in London.

The Thin Client software on both computers will make it appear as though the word processing software is on the computer in London even though the actual word processing application is on a computer in New York.

Every time the user moves the mouse or press a key to type into the word processor at the computer in London, the Thin Client software sends this information to the computer in New York, which also has Thin Client software running on it.

The Thin Client software on the computer in New York calculates the change to the screen when the mouse has been moved, or when keys have been pressed and recalculates the changes to the screen representing the word processor. This is then sent to the computer in London, where the thin client software redraws the changes to the screen.

This happens in milliseconds and gives the user the experience of the word processing software being resident on the computer in London when in fact it is actually resident on the computer in New York.

The screenshot below shows a computer which looks like it's running a word processing application in London, when it's actually connecting to the application on a computer in New York City.

Understanding the principles of technology can be easier to grasp by using analogies, as this makes something which otherwise would have been completely alien, understandable.

So for an analogy to describe how Thin Client technology works, one scene from the James Bond film 'Tomorrow Never Dies' provides a good understanding.

In this film there is a scene, where James Bond, played by Piers Brosnan uses his phone as a remote control to drive his BMW (whilst crouched uncomfortably in the rear foot well of the car) around a multi-storey car park as he's being pursued by some ruthless individuals.

James Bond's phone displays a picture from one of the forward facing cameras mounted on the BMW. He uses the remote control's touchpad, to control the car.

As the car moves around the multi-story car park the pictures are sent back to his phone, which displays them on the phones screen.

The phone itself isn't actually driving the car, it is just sending signals to the car's on-board computer and this computer is then doing all the thinking and carrying out the appropriate actions such as turning the steering wheel, accelerating, braking and so on.

In essence the phone is a dumb device which only sends the driving movements James's makes on the phones screen to the car's on-board computer and in return, the phone receives pictures from the car's cameras.

The remote control by itself doesn't actually drive the car, that's done by the computer on board the car.

Looking at this from a Thin Client perspective, the phone would be a computer which has special Thin Client software running on it. The BMW's on-board computer is like the computer the Thin Client device connects to, which has the applications installed..

The BMW's on-board computer does all the calculations from the instructions it receives from the remote control and sends updates to the phone, in terms of video images to show how the BMW is progressing.

Likewise, the computer, the Thin Client device connects to, does all of the processing and sends image updates to the Thin Client device.

Thin Client vs Fat Client

Whilst the Thin Client approach looks at processing the application logic remotely, that is running the actual application on a different computer to where the user is using it and in turn presenting the user with images of what is happening remotely.

The Fat Client approach looks at processing the application locally, that is on the computer being used by the user. This is the typical approach used by most computer users, where they use a computer at home for instance, which does all the application processing.

The screenshot above (Thin Client versus Fat Client), the word processing software on the thin client is running on a powerful computer in the data centre. Whilst with the fat client approach, the software is running on the computer itself.

Thin Client Software

The market leaders when it comes to Thin Client software are Citrix Systems and the Microsoft Corporation.

Microsoft Remote Desktop Services

Microsoft Remote Desktop Services, known as RDS for short, provides the engine on Windows Server 2008 R2 based systems to allow access remotely.

On older versions of Windows Server including Windows Server 2008 R1, Windows Server 2003 and Windows 2000, Windows Terminal Services is used.

Windows Terminal Services, known as WTS for short, is in essence the same as RDS and Microsoft decided to rename WTS to RDS in their Windows Server 2008 R2 version. The latest version of Windows Server is Windows Server 2012 and also includes RDS.

They've also made a few improvements and enhancements. People still use the words RDS and WTS interchangeably in the real world.

Windows Terminal Services and Remote Desktop Services have been developed in conjunction with Citrix Systems.

Originally Citrix Systems licensed the code from Microsoft for their Windows Server product (NT3.5) and redeveloped this. Citrix Systems released this redeveloped version of Windows Server as Citrix WinFrame.

When the next version of Windows Server was released, NT4.0, Microsoft decided not to give the code to Citrix Systems for them to develop their own version.

Instead Microsoft and Citrix worked together to create Windows Server NT4.0 Terminal Server Edition. Citrix Systems kept some of their technology outside of this joint project, which allowed them to develop their Citrix MetaFrame product.

Citrix Virtual Apps

Citrix Virtual Apps is the latest version of Citrix's thin client product line. Just as with Citrix Presentation Server and its predecessor Citrix MetaFrame, all have been developed outside the joint development work Citrix does with Microsoft with its RDS and WTS products.

That is, Citrix Systems works with Microsoft to help develop their WTS service and later RDS, whilst Citrix Systems gets to keep certain functionality they've developed for themselves. This functionality has become Citrix MetaFrame, Citrix Presentation Server and Citrix XenApp.

Think about RDS and its predecessor WTS as a car which is jointly developed by Microsoft and Citrix. Now think of Citrix also developing some enhancements to this car such as a new fuel injection system, better suspension and a supercharger.

All the products Citrix develops in this analogy need the car to function, as you wouldn't expect a fuel injection system, suspension or a supercharger to work on their own without a car?

The car without these additional components can still work, doing what it was designed for. Just like Microsoft's RDS (WTS for older versions of Windows Server) can still work without needing any Citrix components to function and just like the car analogy, will get you where you want to go.

If you want an improved experience through increase power and improved handling, then the car could have the better suspension added, along with the improved fuel injection system and supercharger.

This is exactly how the Citrix Virtual Apps (including previous versions called Citrix XenApp, Presentation Server, MetaFrame and WinFrame) are positioned. They provide an improved experience for people using and managing their Windows Server and RDS (including WTS) components.

This latest incarnation of the Citrix thin client products called Citrix Virtual Apps has been developed for new versions of Microsoft Windows Server including Microsoft Windows Server 2016 and Microsoft Windows Server 2019.

The Citrix Virtual Apps product line originally started out as Citrix WinFrame, which became MetaFrame, then Presentation Server, then XenApp and is now Citrix Virtual Apps, as shown below in screenshot 6 'Citrix Thin client history' below. It’s important to appreciate many organisations are still using previous versions of Citrix Virtual Apps, such as Citrix XenApp 7.x with many also using XenApp 6 and 6.5, even though many of these versions are end of life (EOL) and out of support from Citrix.

Citrix Virtual Apps Popularity

There are many reasons why Thin Client technologies such as Citrix are popular, not only because Citrix is a great company which has the vision to make great products but because Citrix actually develops products which organisations need.

Citrix have been very clever in the way they've brought out other smaller companies, which has not only opened up new markets for them, but enhanced their already excellent product range.

Technology aside, one of the main reasons for using Citrix is cost especially Total Cost of Ownership, known as TCO for short. You can find more about TCO in Appendix A of this course.

Summary

• Citrix Systems develops Thin Client products such as Citrix Virtual Apps.

• Microsoft RDS (formerly Windows Terminal Services) provides the engine for Thin Client type computing.

• Citrix Virtual Apps works with Microsoft Remote Desktop Services (Windows Server 2012, Windows Server 2016 or Windows Server 2019).

• Fat clients run applications locally that is, on the computer being used by the user.

• Thin clients access applications being run remotely and are not involved in the actual running of the application.

Key Technical Concepts

Terminology introduced below shows what the technology involved is and what it actually does, starting from the basics and building up.

Personal Computers

The 'personal computer' or 'PC' for short has become an important part of the lives of many during the technical advances made in the past twenty years.

Personal computers are used at home, at work, in internet cafes to schools. These computers are used to run software such as word processors, spreadsheets, web browsers (such as Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera) to specialist business applications.

Workstations

Personal computers can also be called workstations, especially in the workplace and generally have slightly more powerful specifications.

For the purpose of this course, workstations and personal computers will be known as desktop computers, as this is also another term used widely to describe personal computers.

Laptops

Portable versions of desktop computers are known as laptops and these are designed to be powerful, yet provide this power on the move, with improved battery life in a smaller form factor. Laptops have become lighter over the years and this improved portability has made them more widespread.

Desktop Operating Systems

Desktop computers run desktop operating systems such as Windows XP, Windows 7 and so on. These desktop operating systems are designed to provide functionality for using software from word processors to web browsers.

Servers

There are other types of computers called 'Servers' which are computers with similar components to desktop computers such as a processor (to do the calculations, also known as a CPU - central processing unit) memory, disks (also known as hard drives) and these components may be more powerful than their desktop computer counterparts.

Server Operating Systems

What really separates the desktop computer from the server computer is the operating system which is used. On a desktop computer, the desktop versions of Microsoft Windows including Windows XP, Windows Vista and Windows 7 is used. Some desktop computers may have desktop operating systems from Apple to Linux desktop derivatives such Ubuntu, Fedora and Debian.

On the server, server based operating systems will be used, so for Windows, Microsoft Windows Server 2003 and Microsoft Windows Server 2008 are popular choices. If it's going to be a Linux based server, then Red Hat Linux is a popular choice.

These operating systems are designed to utilise the server hardware more appropriately than a desktop operating system would. Moreover, the server operating systems are designed to deal with multiple users, whilst a desktop operating system is designed to deal with a single user.

A server operating system would not ideally be used in the same way as a desktop operating system, that is, it is installed on a desktop computer and then used for software such as word processing.

This is like using a bus instead of a car, to transport a single person. It is just an overkill of the power available to do something which could be done with less.

Server roles

Servers can be configured to provide different roles, that is, a server can be assigned a particular duty to perform. So a server could be assigned the role of 'print server' and it would deal with printing, by sending print requests to the appropriate printers.

Servers could be assigned a 'file server' role and would therefore be involved in filing information (storing information on their disks) which can be retrieved when required.

Other server roles include email servers, web servers, database servers and authentication servers to name a few.

Client/Server

Server operating systems tend to operate in a client/server fashion, whereby the client, which is the desktop computer (as well as laptops and smart phones), connect to the server.

Depending on how the server is configured, the desktop computer user will be able to print, store their files, authenticate, send emails and so on using their connection from their desktop computer to a server.

A single server will tend to have many clients that is desktop computers (as well as laptops) requesting services from printing to email (subject to what service the server is set up to provide) from the server.

The services requested depend on what role the server is configured for, so if it is configured as an email server, it will send and receive the email sent from the user's desktop computer (as well as from laptops and smartphones).

The screenshot 'Clients and Servers', above shows several different clients, laptops, computers and smart phones connecting to an email server and a web server.

32-bit versus 64-bit

There's a lot of talk about 64-bit operating systems, as this is the next step in the evolution of computing. Without getting too technical, the difference between 32-bit and 64-bit operating systems is the amount of memory they can use efficiently.

32-bit operating systems can use directly 4 gigabytes (Gb) of memory, whilst 64-bit can directly access up to 2,000 gigabytes (Gb) of memory. This means in theory, more programs can be used on 64-bit machines. Only computers with 64-bit processors can use 64-bit operating systems.

We will only be using the 64-bit versions of operating systems in this course.

Summary

• Servers are powerful computers running server based operating systems

• Clients are desktop computers, laptops and any other devices which require services from servers

• Servers provide services to clients such as printing, email etc.

• Operating systems are software designed to allow people to use computers

• Clients connect to servers for various services such as email

• 64-bit operating systems can access more memory

Introduction to Citrix Concepts

To understand the key concepts of Citrix Virtual Apps, an analogy will be used whereby how a egg site called Pinklebury operates will be compared to how Citrix Virtual Apps operates.

Pinklebury Site

Pinklebury site is owned by John, the site has over 200 chickens in a single chicken coop and they produce around 500 eggs each day.

Owner John has an assistant, his son, Tony who is the lead site hand. Tony keeps tabs on the state of the chickens and how the other site hands are doing.

Johnny, owner John's second eldest son also helps as a site hand and when Tony is not well, Johnny takes the lead site hand role and steps in to do the duties his brother Tony would normally do.

Two other site hands, Paul and Peter also help keep the chicken's producing eggs.

The site has a shop, where all the eggs are sold. The shop is at the entrance to the site and the owner's daughter, Emily works in the shop.

Emily is responsible for making sure there are enough eggs in the shop to sell.

Michael, owner John's youngest son works as a site hand but also works with Emily.

He tells Emily how many eggs and which types of eggs are available, he gets this information by asking Tony.

To keep tabs on how much stock is available and how much is being sold, Lisa, the owner's youngest daughter keeps detailed records.

Before the owner John could set up his egg shop on his site, he had to get a license from the Ministry of Agriculture.

This license sets out the maximum number of people who can use the shop at anyone time.

Owner John can operate his site for 30 days without needing to contact the Ministry to renew his license, after which the site will be closed down immediately if the license is not renewed.

The Pinklebury site screenshot above provides an overview of Pinklebury site and the people who work there.

Citrix Virtual Apps

Now compare how Pinklebury site operates to the key concepts used with Citrix Virtual Apps.

Citrix Virtual Apps Server

The Citrix Virtual Apps servers can be compared to the chickens at Pinklebury site, whilst the chickens do the job of providing eggs for customers, the Citrix Virtual Apps servers provide applications for the users (customers) to use.

Citrix Virtual Apps Site

Just as Pinklebury is a boundary of responsibility for owner John, a ‘Site', the same concept of ‘Site' is used for Citrix Virtual Apps. With the Citrix Virtual Apps Site being the boundary for Citrix Virtual Apps servers and other components within it.

The concept of ‘Site' used to be known as a 'Farm' in older versions of Citrix Virtual Apps to define an area of responsibility and a boundary. The Citrix Farm concept was superseded by the 'Site' concept in later versions of Citrix Virtual Apps.

Collector

The site hand Tony collects information about the chickens, primarily around their capability, that is how many eggs they are producing.

Tony's role is similar to the Collectors role in a Citrix Virtual Apps Site, where information on the availability of resources from the Citrix Virtual Apps servers is assessed.

Just as Tony keeps the information about the chickens in his memory, the Collectors do the same. They keep a watch on how each of the Citrix Virtual Apps servers they are responsible for are performing.

Zones

In Citrix Virtual Apps terminology the chicken coop is represented by a zone and each zone has a Collector for that zone.

Just as Pinklebury site has a backup site hand in the likes of Johnny, who helps when Tony can't work, the Citrix Virtual Apps site can also have a backup Collector for each zone, which can step in, should the preferred Collector stop working.

StoreFront

The Citrix Virtual Apps Site also has a sort of shop front for customers and this is web based and commonly referred to as a portal. The portal is a web interface to the Citrix Virtual Apps site and the component which provides the portal capability is called the StoreFront.

XML Broker

The StoreFront uses a broker to find out what applications are available for users to use, this broker is known as the XML broker.

The XML broker functionality is provided in Pinklebury site by Emily, who can check with the site hand, Tony, to see what eggs are available.

Site Database

With a Citrix Virtual Apps Site, to keep tabs on what applications are available and who is allowed to use them, a database is used. The database keeps detailed records about the applications including locations, who can use them and so on.

This is sort of similar to Lisa's role, where the owner's youngest daughter keeps detailed records.

License Server

Owner John needs a license to operate Pinklebury site from the Ministry of Agriculture and this license, allocates the maximum number of people owner John can provide eggs to.

Citrix Virtual Apps Sites need licenses too and these contain limits for the maximum number of users who can access the Citrix Virtual Apps Site. A Citrix license server is used to provide licenses to the Citrix Virtual Apps Site.

Citrix Virtual Apps Administrators

Citrix Virtual Apps Sites have an administrator, a user who has the required rights to change how the Citrix Virtual Apps Site is set up. Likewise, Pinklebury site has an administrator, owner John, who can also elect to change how the site is set up.

Administration tasks can be delegated to other users in a Citrix Virtual Apps Site by the main Administrator. Likewise, owner John can delegate his administration duties to his wife or he can hire new people to carry out specific or even all of his administration duties.

The screenshot below, shows the basic components of a Citrix Virtual Apps Site.

Service Expansion

Owner John can cater for more demand, by increasing the number of chicken coops or by buying another site and by taking on more site hands to handle the increased workload.

He can still use his shop to sell eggs from the new site but would need to take on a new person to keep detailed records for the new site. As it will be impossible for Lisa to do the record keeping work load of two sites.

The Ministry will need to issue a new separate license for an agreed number of people who can be served eggs from the new site. Likewise a new license will need to be obtained for the new Citrix Virtual Apps site and this can be set up on the existing Citrix License server.

Citrix Receiver Desktop App Windows

Likewise the Citrix Virtual Apps site administrator can create more zones and add more Citrix Virtual Apps servers into each zone to cater for more demand, as shown in the screenshots below.

The administrator can also create a separate Citrix Virtual Apps Site, as shown in the screenshot above. A separate Citrix Virtual Apps site can utilise the existing StoreFront as a shop front to the applications available from both Citrix Virtual Apps sites.

An additional separate database will be required to cater for the data storage requirements of the new Citrix Virtual Apps site.

Technical Citrix Concepts

The analogy of how Pinklebury Site is managed should provide an easier understanding of how the key concepts in the world of Citrix Virtual Apps work.

By taking a look at the key concepts again technically, an understanding of how they work can be more clearly understood.

Citrix Virtual Apps Server

This is a computer which hosts, that is, has the applications (word processor, web browsers etc.) installed on it and provides access to these using Citrix software.

This server runs a server based operating system (Windows Server 2003, Windows Server 2008 or Windows Server 2008 R2) and is configured to use Citrix Virtual Apps software.

The Citrix Virtual Apps software provides enhancements to Windows Server Operating System in terms of application delivery and management.

The Windows Server Operating system requires Terminal Services (Remote Desktop Services and Application Server roles if Windows Server 2008 R2) configured.

Citrix Virtual Apps Site

A Citrix Virtual Apps site is a collection of Citrix Virtual Apps servers, which share a Datastore.

Citrix Datastore

The Citrix Datastore just a database on a database server and a single database server can have several databases, acting as unique datastores for different Citrix Virtual Apps sites. For example, the screenshot below shows Citrix Virtual Apps Site databases on the same server.

The datastore provides a permanent store for Citrix Virtual Apps site information until a time it is changed or removed.

Data Collector

The Data Collector holds an in memory database of Citrix Virtual Apps server information, monitoring their states and available capabilities.

StoreFront

A web based front end where users log in and get presented with information about applications they are allowed to use. The StoreFront talks to an authentication service such as Microsoft Active Directory, to determine whether the user is allowed access to the Citrix Virtual Apps site via the StoreFront.

If the user is allowed access, the StoreFront then speaks to the XML broker and asks it for a list of applications the user is entitled to use. The icons (images with shortcuts, as shown in the screenshot (StoreFront displaying applications and folders) below, are then displayed on the StoreFront web page. When these icons are clicked they launch the remote control access to the applications on a particular Citrix Virtual Apps server. The screenshot below show StoreFront displaying applications and folders.

Citrix Virtual Apps Zones

To partition Citrix Virtual Apps Servers into groups, Citrix Virtual Apps zones can be used. Each zone must have a Citrix Virtual Apps server configured as zone data collector. Whilst it is possible to separate Citrix Virtual Apps servers into separate sites, this would require increased administration and additional components in comparison to partitioning Citrix Virtual Apps servers into zones.

XML Broker

As stated in the StoreFront section, the XML broker is an intermediary for the StoreFront to find out which applications are available to the user.

The XML broker is a program which runs on a server. It is known as a service for two reasons, firstly it provides a service, that is brokering information and secondly, it carries on running on the server listening for requests from the StoreFront, even when there is no one logged on to the server.

Published Applications

The term application is used to describe software such as a Word Processor, Web Browser etc.

The term 'publishing' means presenting users with particular applications. So in the steps to publish an application, the administrator must define what the application is (what it's called, where it's located) and who can access it.

Published applications appear seamlessly on the user's desktop when accessed. This means they appear as though they are running on the user's desktop when in fact they are running on the Citrix Virtual Apps server. Applications on the Citrix Virtual Apps server are still being accessed remotely by the user, but the user is being presented with the application, as if it's actually on their computer.

Published Desktops

Whilst publishing applications involves publishing individual applications, so they appear as though they are running on the user's desktop, publishing desktops, involves presenting the Citrix Virtual Apps servers desktop on the user's computer.

So the user sees what would be seen if they logged onto the Citrix Virtual Apps server directly, as shown in the screenshot below.

Streamed Applications

Citrix Receiver Desktop App

Both publishing applications and desktops gives users remote access to applications and the Citrix Virtual Apps servers desktop respectively. Streaming applications involves sending the application to the user's desktop, to run on the user's computer.

Portions of the application (which have been specially packaged) are sent to the user's computer in sufficient amounts to ensure the application starts.

All the grunt of the application is done on the user's computer, as opposed to published applications where the application processing is done on the Citrix Virtual Apps servers.

Citrix Virtual Apps Services

Previously known as Program Neighbourhood Agent (PN Agent) works a bit like the StoreFront but instead of displaying application icons on a web page in a portal, Citrix Virtual Apps Services actually displays the icons on the start menu of the user's computer, as shown by the Citrix Virtual Apps Services updated Start Menu screenshot below.

Summary

• Citrix Virtual Apps servers are organised into sites

• Citrix Virtual Apps sites can be partitioned using zones, with each zone requiring a data collector

• Web based access to a Citrix Virtual Apps site is provided by the StoreFront

• XML Broker is an intermediary for the StoreFront to find authorised applications

Relation Questions

What is the difference between Citrix Virtual Apps and Citrix Virtual Desktops? Whilst Citrix Virtual Apps is server based, that is you have multiple users connected to a Virtual Server (Microsoft Windows Server), Citrix Virtual Desktops is a single use Virtual PC, running a PC operating system like Windows 7, Windows 10. A single user connects to each Virtual PC with Citrix Virtual Desktops responsible for creating and managing the Virtual PC's.

How does Citrix Virtual Desktops work? Citrix Virtual Desktops uses special provisioning tools to create Virtual PC's on servers running virtualization software (VMWare, Citrix Hypervisor formerly XenServer, Microsoft Hyper-V). These are then managed by Citrix Virtual Desktops so different groups of Virtual PC's can be assigned to users to use.

What is the difference between Citrix Receiver and Citrix Virtual Apps? Citrix Receiver is software installed on a PC, Tablet or Smartphone allowing connection to Citrix Virtual Apps and Citrix Virtual Desktops. Citrix Receiver provides the technology to interact and display the information send from Citrix Virtuals Apps and Citrix Virtual Desktops on the user's device.

What is Citrix and why is it on my computer? Citrix allows you access desktops and applications remotely with the look and feel the same as if they applications were installed on your computer. The Citrix on your computer is a small piece of software called WorkSpace (Receiver older name) that allows the magic of connecting to application and desktops on Citrix servers to be displayed on your computer.
