AWS Elastic Beanstalk

As technology advances, we're on the lookout for software and services that can assist us in quickly and easily putting together new solutions. As long as we're talking about new services, Amazon always has something new to offer, and the latest one is Amazon web service elastic Beanstalk. Keeping track of the web servers that power our SaaS projects. Internal innovation is fueled by these two dynamic web-based platforms. Simply upload your code, and Elastic Beanstalk will take care of everything else, including upgrading existing, load balancing, auto-scaling, and software health monitoring. At about the same time, you retain complete control over the AWS resources that power your application and, therefore, can access them at any time. According to reports, many large corporations are using AWS elastic beanstalk to help them grow their businesses to new heights.

Amazon Elastic Beanstalk

Elastic Beanstalk is an Amazon Web Services (AWS) service for deploying infrastructure that consists of multiple AWS services. AWS S3, EC2, auto-scaling, cloud watch, Elastic load balancer, and simple notification service are among these services. Elastic Beanstalk also handles all updates and patches and security updates for the resources it has provided for free.

In the cloud computing space, there are numerous PaaS solutions. AWS Elastic Beanstalk, on the other hand, remains one of the most popular PaaS options among app developers. You are indeed charged for the resources designed to support your application when you use Elastic Beanstalk to deploy your applications. The hosting platform, coding language interpreter, operating system, safety, HTTPS service, and application layer are all handled by Elastic Beanstalk. All that remains is for you to write your code.

How does Elastic Beanstalk in AWS work?

You must first create a local application on any platform before using the Amazon elastic beanstalk service. Python, PHP, Node.js, and other programming languages are examples. Then you must create an Elastic Beanstalk application with only surroundings in which you can upload your local application. After which, you deploy it and launch it using the URL provided.

There are no additional charges for Elastic Beanstalk in AWS; you only pay for the resources you use to run your application, such as Amazon S3 for storage. Also, the cost is not fixed; it varies depending on the number of EC2 instances, the size of the S3 bucket, and the database instance configuration.

AWS Elastic Beanstalk benefits

Let's take a look at each of the AWS Elastic Beanstalk advantages one by one:

Versatile and Simple to Get Started

The application was simple to deploy on AWS. To upload your application, you could use AWS Management Console, Visual Studio, or Eclipse. AWS EBS automates capacity provisioning, auto-scaling, and application health monitoring deployment details.

Your application would be ready to use in a matter of seconds, with no resource configuration or infrastructure work required on the coder's part.

Autoscaling Options

Once scaling up or down as required, Beanstalk takes good care of it. Beanstalk automatically scales your application based on the amount of traffic it receives. Adjustable Elastic Beanstalk uses auto-scaling settings to automatically scale the application. Your application will be able to handle spikes in workload or traffic while keeping costs low.

CPU Utilisation Metrics, for example, can be used to trigger Auto Scaling actions. It also assists you in lowering costs while maintaining the application's performance.

Productivity of developer

Developers don't have to worry about uploading their app to the internet; all they have to do is focus on making it safer and consumer-friendly. AWS EBS assists you with security, server management and configuration, database management, load balancers, firewalls, and network management.

This has a lot of advantages because it allows you to concentrate solely on writing code instead of performing other tasks. EBS manages the application and is responsible for supervising and operating the infrastructure. It saves time and money in terms of development and expertise.

Customization

You can choose the configuration of your AWS services that you've used with your application with AWS Elastic Beanstalk. Consider Amazon EC2, from which you can select the instance type that is best for your application. You also could change it back to take control of some service's manual process if you want to.

Cost-Effective

The cost of setting up a Beanstalk environment is zero. When it becomes necessary to incorporate it into the application's production, you can expand your application. AWS Elastic Beanstalk has a low-cost structure where you only pay for what you are using because there are no extra charges.

Management and updates

You won't have to worry about keeping your application up to date as the platform evolves. AWS professionals are in charge of software patches, platform updates, and infrastructure management. The AWS management console can be accessed in less than an hour, thanks to the fast access.

AWS Elastic Beanstalk Feature

Application

When you create an application, you usually put all of the related assets in a folder, including code, resource configuration templates, code versions, and required files. Once you implement your application, such as through Elastic Beanstalk, an Elastic Beanstalk application is an entity that holds all of the related files, platform resources, and configuration information to support the application. In the Elastic Beanstalk environment, the file is the application.

Application Environment

The web application that you should have uploaded and it will upload its next improved version is referred to as the Application Version. For instance, suppose you first uploaded your application to AWS Beanstalk and then updated the source code of one's application. Rather than rewriting your prior version of the application, you could really give it a new name that you can compare the two versions with.

Environment Health

If you use elastic Beanstalk to deploy your application, an environment can be created to shelter the version of the application you're deploying. The environment contains the necessary EC2 instances, storage, load balancer, autoscaling groups, and other components for this version of the application.

Scalability

You could indeed start small and work your way up. Elastic Beanstalk allows you to create up to 75 applications, each with 1,000 versions. Allows users to run up to 200 environments in total throughout their applications by default. If your organisation requires additional resources, you can always submit a request form.

Provisioning

Elastic Beanstalk's capacity to provide the required instances, load balancers, as well as other resources which your application requires is one of its strongest features. You don't even have to give any details about the size or type of these resources.

Notifications

When advancement events and activities occur, Elastic Beanstalk can send you notifications. When new servers are launched, new deployments are made, or your defined threshold is exceeded, for example.

Language support

Web applications written in Java,.NET, PHP, Node.js, Python, Ruby, Go, and Docker are supported by AWS Elastic Beanstalk.

Cloudwatch

Elastic Beanstalk also gives you access to CloudWatch. This fine management solution keeps track of your environment using predefined metrics like request count, CPU usage, and inbound and outbound network traffic, giving you a clear picture of your application's health.

What is an Elastic Beanstalk Environment? 

The application's heart is the environment. The environment is depicted in the diagram by the top-level solid line. Elastic Beanstalk provides the resources needed to run your application when you create an environment. AWS resources created include an elastic load balancer (ELB in the diagram), an Auto Scaling group, and one or more Amazon Elastic Compute Cloud (Amazon EC2) instances. 

Web server environment:
The web server environment of elastic Beanstalk has following architecture structure

Elastic Beanstalk Environment

Elastic Load Balancer

Auto Scaling Group

EC2 Instances

Host Manager

Security Groups

Elastic load balancer:
The elastic load balancer routes HTTP requests to the Amazon EC2 instances that have been set up in the environment.

Autoscaling group:
Based on traffic load, the Auto Scaling Group would then scale in and out the number of EC2 instances in the environment. Inside the elastic beanstalk environment's settings, you could indeed clearly state how many EC2 instances you would like to start with and how many you would like the auto scaler to create.

Host manager:
On each of your EC2 instances, the host manager is in charge of tracking and reporting the results of your application, as well as reporting on resource instance-level events and sending logs to your cloudwatch dashboard.

Security group:
For such an elastic beanstalk application environment, a new security group will just be created that will enable HTTP access to your application utilising port 80. You can assign extra security groups or an existing VPC to your web server environment using the make modifications settings elastic beanstalk dashboard.

Worker environment:
A work environment is created to handle specific background tasks, but it will also help your web server application when it is overloaded.

If a second user makes a request while a web application has been processing a time-intensive task in response to a user request, the second user will have to wait, and the request may time out. When tasks on the webserver take too long to complete, elastic Beanstalk would then transfer the user requests to the background worker environment, which also will queue and process the requests in a timely manner. As the requests are passed to the worker for processing, the webserver can recognise multiple requests without scheduling them out.

AWS Elastic Beanstalk is just a calculated service that allows developers to quickly deploy and run applications on the AWS cloud.

Amazon's EC2 service allows users to create a server (what AWS refers to as an instance) in the cloud. You only pay per hour for what you use. You have complete control over this instance and can launch an unlimited number of instances.

Elastic Beanstalk seems to be a layer of the abstract idea above the EC2 layer.

AWS Elastic Beanstalk is a simple service for deploying and scaling web apps and services written in Java,.NET, PHP, Node.js, Python, Ruby, Go, and Docker on well-known servers like Apache, Nginx, Passenger, and IIS.

AWS Elastic Beanstalk is a good example of PaaS.

Elastic Beanstalk's choice - 

It is a poor choice if you require worker processes.

It is not suitable for "mission critical" applications.

It is not ideal if you require a large number of environment variables.
