AWS Identity And Access Management (IAM)

AWS IAM is the heart of AWS security because it empowers you to control access by creating users and groups, assigning specific permissions and policies to specific users, Managing Root Access Keys, setting up MFA Multi-Factor authentication, for additional security, and so much more. And the cherry on top  IAM is free to use!

AWS Identity And Access Management

IAM is preventative security control.

It can create and manage AWS users and groups and use permissions to allow and deny access to AWS resources

IAM deals with 4 terms such as users, groups, Roles, and Policies.

It controls both centralized and fine grained-API resources plus management console.

You can specify permissions to control which operations a user or role can perform on AWS resources

IAM service provides access to the AWS Management Console, AWS API, and AWS Command-Line Interface (CLI)

AWS IAM — Key Features

We should consider IAM the initial move towards making sure about all your AWS administrations and assets.

1) Confirmation:

 AWS IAM allows you to make and oversee characters, for example, clients, gatherings, and jobs, which means you can issue and empower verification for assets, individuals, administrations, and applications inside your AWS account.

2) Approval:

 Access the executives or approval in IAM is made of two essential segments: Policies and Permissions.

3) Fine-grained consents:

 Consider this — you need to give the business group in your association admittance to charging data, yet in addition need to permit the engineering group full admittance to the EC2 administration, and the promoting group admittance to chose S3 pails. Utilizing IAM, you can design and tune these consents according to the necessities of your clients.

4) Common admittance to AWS accounts:

 Most associations have more than one AWS account, and now and again need to designate access between them. IAM lets you do this without sharing your accreditations, and all the more as of late, AWS delivered ControlTower to additionally streamline multi-account designs.

5) AWS Organizations:

 For fine-grained control for various AWS accounts, you can utilize AWS Organizations to portion accounts into gatherings and allot consent limits.

6) Personality Federation

: Many occasions, your association should combine access from other character suppliers, for example, Okta, G Suite, or Active Directory. IAM empowers you to do this with an element called Identity Federation.

Blue-Green Deployment AWS Overview | All You Need To Know

In this blog post, we’ll discuss Blue-Green Deployment, which leads to Zero downtime. Being developers, we must have faced a situation where our applications’ updated version takes the customers’ heat for being slow or buggy. This leads to rolling back to the previous versions of our application, which are stable. Right? But is rollback easy?

As you must have guessed, rollback isn’t as easy as it sounds. It has several shortcomings as it is implemented by redeploying an older version from scratch. This process takes a lot of time, which can make us lose thousands of customers in realtime. Moreover, even if the bug is small, we do not get time to fix it and move to the stable version. So how to solve this problem?

Overview Here comes 

Blue-Green Deployment into

 the picture. Blue-green deployments can reduce common risks associated with deploying software, such as downtime and rollback capability. These deployments give just about a zero-downtime release and rollback capabilities.

The basic idea is to shift traffic between two identical environments, running different versions of your application. Although the colours don’t represent a particular version, the blue colour usually signifies the live version, and the green colour signifies the version that needs to be tested. These can be swapped too. After the green environment is ready and tested, production traffic is redirected from blue to green. If you face any problem, you can always roll back by reverting traffic to the blue environment.

The two environments need to be different but as identical as possible. We can use a load balancer to route traffic between them. They can be different hardware pieces or different virtual machines running on the same or different hardware. They can also be a single operating environment partitioned into separate zones with separate IP addresses for the two slices.Step-by-Step Blue Green Testing Model

In Server A, for instance, we’ll have the green version of our application which needs to be deployed to the live production environment. You want to ensure that the update won’t interrupt service and that it can easily be rolled back if any major errors are found. Here comes the Blue-Green deployment model into the picture.

Deploy the updated version of the application (Blue version) to Server B. Run any applicable tests to ensure that the update is working as expected.

Configure the router to start sending live user traffic to Server B.

Configure the router to stop sending live user traffic to Server A.

Keep sending traffic to Server B until you can be certain that there are no errors and no rollbacks will be necessary. If a rollback is necessary, configure the router to send users back to your Green version on Server A until they can be resolved.

Remove the Green version of your application from Server A, or update it to your Blue version so it can continue serving as a back-up version of your application.

Create And Connect To Amazon AWS Windows EC2 Instance

The 

EC2 is a computing service that provides scalable computing capacity and eliminates the investment in hardware up-front, so the applications can be developed and deployed faster. Virtual machines on AWS EC2, are called instances. Here in this blog, we are going to covers  how to launch a Windows-based instance. What Is Amazon EC2?

Amazon EC2

 is a web service that provides secure, resizable compute capacity in the cloud to the users. The EC2 allows us to configure the capacity, it also provides complete control on all over your computing resources. An AWS user can increase or decrease instance capacity as per need by using the Amazon EC2 web interface or an application programming interface (API). A developer can code an application to scale up and down instances automatically with AWS Auto Scaling. A user can also define an autoscaling policy and group to manage multiple instances.Why We Use Amazon EC2?

The organizations have to invest a huge amount in buying hardware components and to manage them is more hectic than buying so the Amazon EC2 eliminates the investment in hardware upfront, so you can develop and deploy applications faster. Using Amazon EC2 you can launch as many or as few virtual servers as per your need, manage storage, configure networking and security. Amazon EC2 enables you to scale up or down to handle changes in requirements or spikes in popularity, reducing your need to forecast traffic.How Amazon EC2 Works?

A User Can choose EC2 from the AWS Services dashboard and ‘launch instance’ in the EC2 console. The User can also select either an Amazon Machine Image (AMI) template or create an AMI containing an operating system, application programs, and configuration settings. The AMI is then uploaded to the Amazon S3 and registered with Amazon EC2, creating an AMI identifier, and then the user can increase or decrease the instance capacity as per need. Amazon CloudWatch allows us to monitors the EC2 Instances and Amazon cloud applications and resources, it allows users to set alarms, view graphs, and get statistics for AWS data and AWS Marketplace.Features Of Amazon EC2

Reliable: Amazon EC2 offers a highly reliable environment where the replacement of instances is rapidly possible.

Secure: Amazon Virtual Private Cloud where Amazon EC2 works and provides a secured and robust network to resources.

Flexible tools: Amazon EC2 provides the tools for developers and system administrators to build failure applications and isolate themselves from common failure situations.

Inexpensive: Amazon EC2 wants us to pay only for the resources that we use on an hourly basis. It includes multiple purchase plans such as On-Demand Instances, Reserved Instances, Spot Instances, etc. which we can choose as per our need.

Use Cases Of Amazon EC2

Hosting environments: Mostly Amazon EC2 uses for hosting a website and application on the cloud. The best part of Amazon EC2 is that it provides a Dynamic and Scalable environment that its compute capacity can grow as per the need of the application. Companies like Netflix, Reddit are the best proof of the EC2 hosting success.

Backup and disaster recovery: Companies hold Amazon EC2 as a medium for performing disaster recovery for both active and passive environments. Amazon EC2 turns quickly in case of an emergency that means businesses have access to the fastest failover with minimal downtime of their application.

High-performance computing: The Amazon EC2 provides virtualized servers that provide high-performance networking and high compute power. An organization like NASA and Pfizer employs the use of high-performance computing using the Amazon EC2 Instance.

Development and test environment: Amazon EC2 is scalable in nature, so now the organization has the ability to create and deploy large scale testing and development environment with unprecedented ease. Amazon EC2 eliminates the investments in hardware and also provides a scalable solution

Banking and financial sector: These are the sectors where they demand maximum scalability and security, both are provided by Amazon EC2. Amazon cloud builds trust by providing highly secure services. Retail and commercial banks, insurance providers, and major payment platforms rely on AWS.

AWS Database Services — Amazon RDS, Aurora, DynamoDB, ElastiCache

AWS Database Services

 are Amazon’s fully managed and scalable database solution for your applications. Amazon provides a wide range of database options such as Amazon RDS, Aurora, DynamoDB, ElasticCache, and Redshift.

AWS Database Services

AWS offers a wide range of database options that you can choose for your applications. AWS database services mainly fall into two categories: 

Relational and non-relational.

Amazon RDS — Aurora, Oracle, PostgreSQL, MySQL, MariaDB, SQL Server

DynamoDB

ElasticCache — Memcached, Redis

Redshift

Amazon Relational Database Service (Amazon RDS)

Relational databases

 store data in a table form with rows and columns and use SQL query language to query the data. In these databases, columns represent attributes and rows represent records. Each field in the table represents a data value.

Amazon Relational Database Service (Amazon RDS)

 makes it easy to spin up a database in the AWS cloud in just a few minutes. Amazon RDS is the most commonly used and a managed database service that automates all the time-consuming administration tasks such as provisioning, setup, patching, and backups.

Amazon RDS provides six different relational database options:

Amazon Aurora

Oracle Database

PostgreSQL

MySQL

MariaDB

Microsoft SQL Server

Amazon RDS Use Cases

Web and mobile applications

E-Commerce applications

Mobile and online games

Amazon DynamoDB

DynamoDB 

is Amazon’s long-running 

NoSQL database

 solution since 2012. NoSQL databases originally refer to as 

“non-SQL”

 or 

“not only SQL” 

or 

“non-relational”

 databases. NoSQL is commonly used to handle big data — large volumes of unstructured or semi-structured data.

Amazon DynamoDB is a fast, fully managed NoSQL database service that supports flexible data models such as both document and key-value data models. It is used for all applications that need consistent, single-digit millisecond performance latency at any scale.

Amazon DynamoDB Use Cases

Ad tech

Gaming

Retail

Banking and finance

Media and entertainment

Software as a service (SaaS)

Amazon ElastiCache

ElastiCache

 is AWS 

in-memory database

 solution that makes it easy to deploy, operate, and scale an in-memory cache in the cloud. It provides faster retrieval of information from fast, managed, in-memory caches instead of relying entirely on slower disk-based databases, thereby improving the performance of web applications.

Amazon ElastiCache

 offers two open-source in-memory cache database engines:

Memcached: Simple and easy solution to start with, ideal for small and static data.

Redis: It provides support for Multi-AZ, backup & restores, and persistence. It is ideal for more dense and complex data.

Let’s take a look at some basic differences between Memcached and Redis.

Amazon ElastiCache Use Cases

Session stores

Gaming

Geospatial services

Real-time analytics

Amazon Redshift

Amazon Redshift

 is a 

data warehousing solution

 used for business intelligence applications. It is a fast and powerful, fully managed, petabyte-scale data warehouse service in the cloud. This service manages all the work of setting up, operating, and scaling a data warehouse. It also manages all administrative tasks including provisioning capacity, monitoring and backing up the cluster, and applying patches and upgrades to the Amazon Redshift engine.

An Amazon Redshift 

cluster

 is a set of nodes, which has one 

leader node

 and one or more 

compute nodes

. Each cluster contains one or more databases and runs an Amazon Redshift engine. The type and number of compute nodes that you need depend on the size of your data, the number of queries you will execute, and the query execution performance that you need.Amazon Aurora

Amazon Aurora 

is the managed relational database solution of AWS. It is a MySQL and PostgreSQL-compatible relational database engine that improves the speed and high-availability of databases. Recently, AWS also launched the serverless and multi-master versions of Aurora, and any of these features can alone be the reason to choose it.

Amazon Aurora delivers up to five times the performance of MySQL and three times the performance of PostgreSQL databases at a much lower price. It also supports cross-region read replicas.

Aurora provides more reliability in terms of storage. Its database storage is separate from the instances. Aurora allows your data to be replicated in 6 storage nodes, each of 10GB chunks, distributed in 3 Availability Zones. For each Aurora database instance, you will have 6 copies of your data, two in each Availability Zone.

Amazon Aurora Use Cases

Enterprise applications

Software as a Service (SaaS) offerings

Web and mobile gaming applications

AWS Route 53 Introduction

AWS Route 53

 is one of the most popular and widely used services of Amazon Web Services. This is generally because it is highly available and reliable and flexible for customer/user to use.

Overview of Route 53 Amazon Route 53

 is a highly efficient and scalable cloud web service and is also used for health checking of resources. It provides developers with an efficient and extremely reliable way to connect users to internet applications without any downtime, it still has downtime in servers or applications but users/customers may not be aware of it. It effectively connects user requests to AWS such as Amazon EC2 instances, Elastic Load Balancing, or Amazon S3 buckets. AWS Route 53 mainly performs three functions:-

It registers the name for the website (Domain name) which needs a name. Like if you want to buy a domain name, you that domain name through Route 53.

It helps the user to connect the website or web application with the browser in the server when he/she enters the website name.

It keeps checking the health of resources before the customer notices it by sending an automated request over the internet to resources.

Benefits Of Using Route 53

Highly efficient and reliable ensures a consistent ability to route applications.

It can handle millions of millions of requests because it is highly scalable.

It can handle large queries without user interaction.

It’s very easy to use, to sign up, configure and provides fast responses.

It’s very cost-effective like pay only for the services you used.

It’s very secure, because of Identity and Access Management (IAM).

Key Features Of Route 53

DNS Failover:- It helps the user to automatically detect an outage of its website and then redirect your end users to another location where your website/application is working properly.

Traffic Flow:- It routes end users to the endpoint which provides a better user experience.

Healths Checkups:- It automatically checks and monitors the health and performance of the applications or resources as well as of resources.

Weighted balancing:- It routes traffic between several services via a round-robin algorithm. It also allows the user to set its own weight.

Root Domain Website Hosting:- It allows the user to access its website without specifying the www in the web address or the search bar.

Domain Registration:- It registers the domain name of the website (if needed), with the AWS console.

ELB Integration:- Route 53 helps the user to easily map his /her root domain because route 53 is integrated with Elastic Load Balancer (ELB). It can be implemented in very little time while maintaining a high level of reliability with customers.

Scalable − It can handles large volume queries without the user’s interaction automatically.

AWS Database Migration Service

AWS Database Migration Service (DMS) is a managed service

 that provides a quick and secure way to migrate your on-premise databases to the cloud. As a result of the migration to AWS, you can deliver up to 3x more features to the market, save on average 31% of your maintenance costs, and boost the productivity of your IT staff by 62%.

AWS DMS is a managed and automated service, however, it is not a fully-automated service. You will still need to set up a few things before starting the migration, which requires a comprehensive understanding of 

AWS Database Migration Service 

and components. In this blog, I will explain AWS DMS, its benefits, components, and finally, we will see the steps for migrating an On-Premises Oracle Database to Amazon Aurora MySQL.What is AWS Database Migration Service?

AWS Database Migration Service (DMS) is a managed and automated service

 that provides a quick and secure way to migrate database from on-premise databases, DB instance, or database running on EC2 instance to the cloud. It helps you modernize, migrate, and manage your environments in the AWS cloud. Amazon provides a wide spectrum of databases to work with such as Amazon RDS, Aurora, DynamoDB, ElasticCache, and Redshift.

DMS can be used to migrate relational databases, data warehouses, NoSQL databases, and other types of databases into the cloud. AWS DMS supports 

homogeneous (i.e. Oracle to Oracle) and  heterogeneous (i.e. Oracle to Amazon Aurora)

 database migration. During migration the source database remains operational, thereby minimizing the downtime. The entire migration process can be controlled from the AWS Management Console.AWS DMS Benefits

AWS Database Migration Service

 has various benefits over traditional migration methods such as:

Minimal downtime — DMS continuously replicates the changes to your source database during migration while keeping your source database operational. This allows you to switch over at any time without shutting down either database.

Supports Widely Used Databases — AWS Database Migration Service can migrate your data to and from most of the widely used commercial and open-source databases.

Fast & Easy Setup — A migration task can be set up within a few minutes in the AWS Management Console.

Low cost — DMS is a free migration service for migration to Aurora, Redshift, DynamoDB, or DocumentDB. For other databases, you have to pay based on the amount of log storage and computational power needed to transfer.

Reliability — DMS is a self-healing service and will automatically restart in case of an interruption occurs. DMS provides an option of setting up a Multi-AZ (availability zone) replication for disaster recovery.

Difference Between AWS CloudWatch and CloudTrail

CloudWatch vs CloudTrail

Amazon CloudWatch and CloudTrail

 can be very easy to confuse with these two services. CloudWatch mainly  monitors performance, whereas CloudTrail mainly monitors actions in your AWS environment.What is CloudWatch?

Amazon CloudWatch is basically a monitoring service for your AWS cloud resources and for the applications you run on AWS. It enables monitoring for EC2 and other cloud services so that you get an alert when there anything goes wrong. It provides insights about your applications and your AWS cloud resources from which we can run our application smoothly and efficiently. You can use CloudWatch to detect anomalous behaviour, set alarms, visualize logs, take automated actions, to get a unified view of operational health. It offers free basic monitoring services for your resources, like EC2 instances, EBS volumes, etc. CloudWatch provides two types of monitoring services:-

Basic Monitoring: — It is a free service that includes polls every 5 minutes, 10 metrics, 5GB of data ingestion, 5Gb of data storage.

Detailed Monitoring: — It is a chargeable service that includes polls every minute and is charged per instance per month.

How does CloudWatch work?

CloudWatch collects monitoring and operational data in the form of logs, metrics, and events, and visualizes automatically using dashboards so we can get a unified view of our AWS resources, your applications, and services that run in AWS. You also can set alarms based on the metric value you specify. We can also set up automated actions that will notify us when the alarm is triggered and it will start taking actions against it automatically which helps us to reduce resolution time.

Benefits of CloudWatch

Amazon CloudWatch allows us to access all our data from a single platform only. It is integrated with more than 70 AWS services.

Metrics: By using the AWS CLI or an API, our AWS consultants can publish your metrics to CloudWatch. With the AWS Management Console, you can display the statistical graphs of reported metrics. As a collection of data points, CloudWatch stores data concerning a metric. There’s an associated time stamp for each data point. You may also publish a data point aggregated set called a statistic set.

Alarms: The CloudWatch Alarms feature allows us to monitor the CloudWatch metrics and alerted when metrics fall below the configured levels (high or low thresholds). We can apply multiple warnings to each metric, and there can be multiple actions for each one.

Scalability: The scalability allows us to monitor the usage of the CPU.

Auto Recovery: This feature allows us to recover or reboot the instance if it fails a system status check.

Operational costs: CloudWatch offers perceptions in real-time so that operating costs and AWS resources can be enhanced.

Pricing of CloudWatch

We can start using Amazon CloudWatch for free but the free tier has certain limits after which we will have to pay for what we use and will be charged at the end of the month, the free tier includes: –

Metrics: –a. Basic Monitoring Metrics (at the 5-minute frequency)b. 10 Detailed Monitoring Metrics (T 1-minute frequency)c. 1 Million API requests

Dashboards: — 3 Dashboards for up to 50 metrics per month

Alarms: — 10 Alarm metrics

Logs: — 5GB Data (ingestion, archive storage, and data scanned by Logs Insights queries)

Events: — It includes all events except custom events

Contributor Insights: — 1 Contributor Insights rule per months

Synthetics: — 100 canary runs per months

What is CloudTrail?

AWS CloudTrail is a tool from AWS which provides governance, auditing, compliance monitoring, risk monitoring of your AWS account. It is called a Management and Governance tool in the AWS console. With the help of CloudTrail, we can watch the event history of our AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command-line tools, and other AWS services. We can also use CloudTrail to detect unusual activity in our AWS Account.

How does CloudTrail work?

AWS CloudTrail tracks the user activity and detects unusual API usage

It captures and records the activity as a CloudTrail event.

Now it delivers the events to the AWS CloudTrail console, S3 bucket, and optionally CloudWatch Logs.

With the use of CloudWatch Alarms and Events, it takes action when important events are detected.

Users can review recent events in the AWS CloudTrail console and can download the activity of Cloudtrail with the help of CloudTrail history.

Benefits of CloudTrail

Security Analysis: — It allows the user to discover and troubleshoot security and operational problems by recording a detailed history of changes that occurred at intervals in the AWS account.

Simplified Compliance: — Simplify your compliance audits with AWS CloudTrail by automatically capturing and storing event logs for activities performed within your AWS account.

Security Automation: — It allows the user to track and automatically reply to the account for the safety purpose of the Amazon resources.

Visibility into user and resource activity: — By capturing AWS Management Console activities and API calls, Amazon CloudTrail can improve user and resource activity visibility.

Pricing of CloudTrail

If you set up a single trail to offer a single copy of management events in every area, Amazon CloudTrail pricing is free of charge. With CloudTrail, for all management events, you can also download, filter, and access data from the last 90 days at no cost. In addition, by allowing Analytics on your trails, you can use AWS CloudTrail Insights. AWS CloudTrail Insights are charged per the number of events you used in each region. Pricing is as follows:

Management Events: $2.00 per 100,000 events

Data Events: $0.10 per 100,000 events

CloudTrail Insights: $0.35 per 100,000 write management events

Invoking One Integration From Another

In this blog, we are going to discuss, How to use Oracle Integration Cloud Service’s Call Integration Action feature to invoke an integration from another integration.

It is particularly useful when you need to have multiple small nested integrations rather than having one large integration. It is easier to diagnose errors when you have multiple small nested integrations. If you want to know more about How to Managing & Monitoring Integration Errors in Oracle Integration Cloud (OIC) check our blog.

If you are new to OIC and want to get familiarise then check our blog Oracle Integration Cloud (OIC) For Beginners Overview

Activate and Test Sample Hello World Integration

We will be using the sample Hello World integration as the integration to be invoked (Child Integration) and Hello World Invoke integration will be used as the parent integration that will invoke the child integration. Both the integrations are provided as a sample but we will simplify the Invoke integration part for easy understanding.

Click on Activate Button to activate the integration.

Click on the play button.

A new Popup will open. Click on the Test.

A new page will open that will be used to test the integration provide Details Like Name, Flowid, and Email. Then click on the Test button.
