How to deploy the WAR file in AWS Elastic Beanstalk?

The Amazon Cloud platform’s “Elastic Beanstalk” function makes it simple to deploy a WAR file.

Elastic Beanstalk is a service that allows us to simply deploy and manage code in the AWS Cloud, especially without having to worry about the infrastructure where it is delivered. The idea is to just upload the bundled Web Application file (or specify its location using an S3 bucket) and Amazon would handle the rest.

Elastic Beanstalk supports apps written in Go, Java,.NET, Node.js, PHP, Python, and Ruby. When we deploy the app, Elastic Beanstalk creates the selected supported platform version and allocates one or more AWS resources, such as Amazon EC2 instances, to run the app.

Elastic Beanstalk employs a model based on versions and environments, allowing us to simply move between deployed versions or add/remote environments for the app. A setup is there which consists of several AWS entities and indicates:

• The EC2 instance hosting the Web Application
• The software used
• The rolling policy
• The auto-scale policy

The AWS console makes it simple to construct apps. We can select the platform at the environment level, where Amazon supports a wide range of technologies.

We can use the AWS console to submit source code. Once loaded, the environment will start up. That is, Amazon AWS will create all of the necessary assets so that the Web App can start.  The assets include an EC2 instance, IAM roles, and, if necessary, a load balancer.

We can include RDS DB within EBS instances, but they will terminate after the destruction of the environment, hence this is not a good option for production Web apps.

Elastic Beanstalk is free. We have to pay for only the resources we create, which is a unique feature.

When the environment boots up, AWS will give a basic health check as well as the public endpoint from which the application can be accessed. We can also track recent events from the same page.

Once the environment is up and running, we can upload a new version of the code directly from the console. AWS will save the application package to an S3 bucket and deploy the updated version to the environment (following the deployment policy specified in the environment configuration).
