Java Virtual Machine (JVM)

Java bytecode can be executed in a virtual runtime environment called the Java Virtual Machine, or JVM. Java bytecode is loaded, checked, and executed by the JVM. Every type of processor has a unique machine language that can only be used to represent a program if it is expressed in that language. Programs written in high-level languages must first be converted into the machine language of the specific processor in order to be run on a computer. Compilers are specialized computer programs that carry out this translation. As a result, the compiler receives a high-level program at the entrance and converts it into a program that can be executed by a machine. Then, this machine-language program may be run countless times. Machine language is still used to compile Java programs. However, that machine language was created by a Java Virtual Machine, a hypothetical computer (JVM). A software implementation of a real machine is a virtual machine. Java was created with the idea of WORA in mind (Write Once and Run Anywhere). The java file is first converted into a class file by the compiler. JVM receives the class file and loads and runs it. Java bytecode refers to the machine language of a Java virtual machine. As a result, the Java program is converted into a JVM machine language, which cannot be run directly on a physical computer. A Java bytecode interpreter, which is included with JVM, is required on the computer in order to run a Java program that has been converted into Java bytecode. For each type of machine, a distinct Java bytecode interpreter is required (different versions of JVM), but they all work the same. One of the key differences between Java and other languages is that the same Java program can run on several computer kinds after being translated or compiled. Also, did you know that java is both interpreted and compiled language as a compiler converts a program from one level of language to another and an interpreter converts a program at one level to another programming language at same level, in Java, the Just is Time Code generator converts the bytecode into the native machine code which are at the same programming levels. Hence, Java is both Compiled as well as Interpreted Language.

What is RAM, and how to read it.

1) what is RAM ?

RAM stands for random access memory. This is where a PC stores data before it's processed. ... RAM is a form of volatile memory, which means that it only holds onto data while the chip is powered and erases everything when you shut down the PC. RAM memory is measured in gigabytes (GB).

2)Why we use RAM ?

RAM stores the information.Your computer is actively using so that it can be accessed quickly. The more programs your system is running, the more memory you'll need.

3)Can you read RAM?

The answer is big yes. The contents of RAM can be changed at any time by overwriting it with other data and instructions. On Windows, the contents of physical memory can be accessed through the \Device\PhysicalMemory object in the Object Manager. This requires kernel-level access to the system, which means you would need to install a program, most likely a kernel-mode driver, to access this object.

Hope you get the short info about RAM guys , soon i will post the method of how to read RAM. Thank you!

 APACHE WEBSERVER CONFIGURATION IN DOCKER USING ANSIBLE ⚜

Now the question is what is docker and what is ansible ???

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications.

Ansible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs.   

SO basically our task is : 

🔰Write an Ansible PlayBook that does the following operations in the managed nodes: 🔹 Configure Docker 🔹 Start and enable Docker services 🔹 Pull the httpd server image from the Docker Hub 🔹 Run the docker container and expose it to the public 🔹 Copy the html code in /var/www/html directory and start the web server

Lets do it :)))) 

So lets know some of the concept of ansible first : 

Ansible Playbooks :

Ordered lists of tasks, saved so you can run those tasks in that order repeatedly. Playbooks can include variables as well as tasks. Playbooks are written in YAML and are easy to read, write, share and understand.

♦️ Inventory :

A list of managed nodes. An inventory file is also sometimes called a “hostfile”. Your inventory can specify information like IP address for each managed node. An inventory can also organize managed nodes.

♦️ Control Node:

Any machine with Ansible installed is known as controller node. You can run Ansible commands and playbooks by invoking the ansible or ansible-playbook command from any control node. You can use any computer that has a Python installation as a control node - laptops, shared desktops, and servers can all run Ansible. However, you cannot use a Windows machine as a control node. You can have multiple control nodes.

If you want to install ansible use below commands : 

pip3 install ansible

yum install sshpass

ansible --version >> TO check version

Lets do the project :: 

So this is my managed nodes where we will use ansible book to automate docker  using ansible : 

so In this picture you can clearly see we dont have docker , HTTPD and hostname is Managed_node so  Lets automate : 

IP : 192.168.147.139 

And this is my controller nodes from where we will automate the managed Node : 

IP : 192.168.147.138 

So Let do :: 

If this shows its means you are ready to go : 

Lets create yaml file and automate the managed Node : 

Finally created the yml file :) 

And now if we are trying to go to this url we will reach to our destination :)  : http://192.168.147.139:32771/Search/index.html  

So we come to the end of our task : 

Thanku || hope you all enjoy my task |

Great Session...organised by Linux World

Hello Guys, yesterday we had an exciting session on Industry Use cases on Automation using Ansible. This was one of the greatest session I had with LinuxWorld’s ARTH — The School Of Technologies platform. We had Arun Eapen and Sreejith Anujan (Both from RedHat) with us for almost two and a half hour. I thank LinuxWorld team for arranging such an amazing session. This is the best session till date.

We have knowledge on Ansible(RH294 Level) but Sreejith Anujan helped to get to know about the Ansible Tower(GUI Based Ansible) platform. Till the complete session, we feel good using Ansible Tower, which behind uses Ansible.

Few best things I collected from session :

To teach is to learn twice Terraform + Ansible = Terrible ….

Session Highlights : We had three demonstrations on Industry use case using Ansible. Sreejith Anujan was the one demonstarting all those activities. Demos: 1. Provisioning AWS EC-2 Instance using Ansible Tower Job Template ( Creates VPC, Subnet, Route Table, IGW, gives public IP).

Since we already created such playbook for launching EC2 Instance, I feel better when Sreejith Anujan was doing.

2. Creating Workflow which involves Approval(notified via Slack API)

This was the one, we are very excited while Sreejith was doing. Its almost like a orchestration which involves workflow(like if an event fails do this else do that). Here, when a job templates run successfully, then for running next job templates, it involves Granting permission from the persons via any Messaging API(Here Slack).

3. Launching Oracle Cloud Instance Here we already know that Ansible by defaults doesn’t support many APIs. They are many such cases where we dont have any API for a particular use. Here using pip module, we can install those API based packs to get those functionality from Ansible/Ansible Tower. Here I get to know about the Collections which are like Official Galaxy(Roles) from RedHat.

And Finally the QnA session went very good. Even though I have asked many questions for which I didnt get any reply, I am sure that Vimal Daga sir’s session would helps me to solve the same questions by myself.

Looking forward for many such sessions !!!!!!

I thank Vimal Daga Sir , Preethi Mam, Abid Matoo, Arun Eapen,

Hi people,

First time, i have created a project completely on my own from scratch

It uses docker technology + rsyslog

I made this under iiec rise community ...a video lecture series my vimal daga sir

It monitors the logs of containers of your network and provide basic firewall services.

It creates one centralized server which receives logs

and log clients which send logs to server

It can also ssh and run commands at other devices

I'm still working on pi-hole for firewall services but as you can see I'm new to both linux and docker..so it will take some time

It has Apache server running all the time by default...so you can configure your website through this....

Any other ideas to improve this would be appreciated.

This is a link to my docker image

And being a noob...i still can't put this on github yet...but you will find readme.md atleast there

And if you want to see the lecture series:

https://www.youtube.com/playlist?list=PLAi9X1uG6jZ30QGz7FZ55A27jPeY8EwkE

Take a look ...I learned a lot making such a simple project but after all every story has a beginning

Microservice Design Pattern and Principles

What are MicroServices? Microservices, also known as microservice architecture, is an architectural approach that builds an application as a set of tiny independent services based on a business domain. Each service in a Microservice Architecture is self-contained and implements a single business feature.

Microservice Design Patterns and Principles:

Design for Failure The goal of microservice architecture is to build mistake and robust software products. One microservice's memory leak, database connectivity difficulties, or other issues must not bring the entire service down. The circuit breaker pattern can be used by services in a microservices-based solution.

Discrete Boundaries Microservices are tiny, self-contained chunks of functionality that are easier to maintain and grow. Each microservice in a discrete microservice architecture is accountable for a distinct job. Cross-functional relationships between services should be avoided while creating a microservices architecture. Instead of calling your authentication and authorization service, have your profile management service call an API gateway first.

Single Responsibility Principle A single concern implies that a microservice must only accomplish one thing. This makes it easy to manage and scale the microservice. It also implies that no side activity, such as supplying updating employee data in response to an authenticated answer, should occur.

Decentralization In a microservices, each services is self-contained and offers a single business feature. An application is structured in such a way that it delivers a collection of small separate services based on a business world. For example, if one service failure occurs or falls down, the entire application remains operational.

Microservices: Observability and Monitoring In contrast to monolithic applications, each service in a microservices-based programme maintains its own copy of the data. The goal of microservice architecture is defeated when many services access or share the same database. Ideally, each microservice should have its own database. This would software shall to be have central access management while also seamlessly integrating audit monitoring and caching.

Microservices Architecture

What exactly are Microservices ?

Microservice architecture is a distinct approach to software development that focuses on creating single-function modules with well-defined interfaces and operations.The tendency has expanded in recent years as businesses strive to become more Agile, embracing DevOps and continuous testing.

Microservices provide several advantages for Agile and DevOps teams; as Martin Fowler points out, Netflix, eBay, Amazon, Twitter, PayPal, and other software titans have all transitioned from monolithic to microservices design.

### Different from Monolith Architecture:

A monolith application, as opposed to microservices, is created as a single, self-contained entity. As a result, any modifications to the program are delayed since they influence the entire system. A change to a tiny area of code may need the development and deployment of a complete new version of software. To scale a given application function, you must also scale the entire application.

### Microservices' Characteristics 

Multiple Components It may be divided into several component services. Why? So that each service may be launched, changed, and redeployed individually without jeopardizing the application's integrity. This manner, instead of redeploying complete apps, you may just need to modify one specific service.

Designed for Business Microservices architectures are often organized around business capabilities and goals. Unlike typical monolithic development approaches, where various teams specialize in, example, user interfaces, databases, technological layers, or server-side logic, microservice architecture employs cross-functional teams.

Routing Made Simple Microservices function similarly to traditional UNIX systems in that they receive requests, process them, and create a response. This is contrary to how many other products, such as ESBs (Enterprise Service Buses), operate. This is where high-tech systems for message routing, choreography, and the application of business rules come into play.

Decentralized Because microservices incorporate a diversity of technologies, traditional techniques of centralized governance are ineffective. The microservices community prefers decentralized governance so that its developers may create solutions that others can use to tackle similar challenges. Microservice design, like decentralized governance, encourages decentralized data management.

Resistant to Failure Microservices, like a well-rounded child, are built to deal with failure. Because numerous different services interact, it's very conceivable that one of them will fail (for example, if the supplier is unavailable). In these cases, the client should enable its adjacent services to continue operating while gently exiting.

Evolutionary It's an evolutionary design that's great for evolving systems where you can't predict which devices will contact your application in the future. Many systems begin with a monolithic design, but when new requirements emerge, they may be gradually updated to microservices that interface with an earlier monolithic architecture via APIs.

### Benefits Of Microservices:

Easier to implement

Deploy in chunks to avoid interfering with other services.

Easier to comprehend

Because the function is separated and less reliant, the code is easier to read.

Reusable across the company

Distribute modest services such as payment or login systems around the organization. 

Improved defect isolation

When a test fails or a service goes down, isolate it as soon as possible.

Change risk has been reduced.

Avoid committing to certain technologies or languages; instead, modify on the fly with minimum risk.
