Managing Elastic Beanstalk Application Version Limits

Answer - B.

The AWS Documentation mentions the following.

Each time you upload a new version of your application with the Elastic Beanstalk console or the EB CLI, Elastic Beanstalk creates an application version.

If you don't delete versions that you no longer use, you will eventually reach the application version limit and be unable to create new versions of that application.

You can avoid hitting the limit by applying an application version lifecycle policy to your applications.

A lifecycle policy tells Elastic Beanstalk to delete application versions that are old or delete application versions when the total number of versions for an application exceeds a specified number.

Options A and C are invalid because they are not the right approaches when managing the deployment of application versions.

Option D, even though possible, is not the most effective way.

The correct answer is A. Create multiple environments and deploy the different versions to different environments.

Explanation: Elastic Beanstalk is a service that simplifies the deployment and management of applications on AWS. Elastic Beanstalk allows developers to upload their code and run the application in the cloud. Each time you upload your code, it creates a new version of your application.

However, Elastic Beanstalk has a limit on the number of application versions that can be deployed at the same time. If you reach this limit, you will not be able to deploy new versions until you delete some of the old versions. This can be a problem if you need to keep older versions of your application for testing or rollback purposes.

To manage this issue, you can create multiple environments and deploy different versions of your application to different environments. Each environment is a separate instance of your application, with its own URL, configuration, and resources. You can have multiple environments running simultaneously, each with its own version of the application.

For example, you could have a production environment, a staging environment, and a development environment. Each environment could have a different version of your application, and you could deploy new versions to each environment independently. This allows you to test new versions of your application in a controlled environment before deploying them to production.

Creating an Application Version Lifecycle policy (option B) is not the most effective way to manage this issue, as it only automates the deletion of old versions. This may help to prevent hitting the version limit, but it does not provide a solution for keeping multiple versions of your application for testing or rollback purposes.

Creating multiple applications (option C) is not necessary, as Elastic Beanstalk allows you to create multiple environments within a single application. Creating multiple applications would add unnecessary complexity to your deployment process.

Deleting application versions manually (option D) is not a sustainable solution, as it is time-consuming and prone to human error. It is also not a good practice to delete application versions without proper testing and approval.
