In this blog post, we will discuss how to deploy a new application version in Elastic Beanstalk.

How to deploy a new application version in Elastic Beanstalk:

Elastic Beanstalk automatically creates an application version whenever you deploy an application for the 1st time, create a new environment of existing application or upload source code to an existing application version in existing environment. Application version enables an application developer to undo redo changes in application. For example, suppose your latest deployment has some bug, you can quickly apply the previous working version of your application using application version. Application version also support source bundle stored in S3, where you keep your new application version ready by uploading it to an S3 bucket without deploying it. Elastic Beanstalk deletes these application versions according to the application’s lifecycle policy or when you delete the application.

Next, we are going to deploy a new application version to our PHP web application.

Prerequisite for this demo:

  • PHP web application deployed to Elastic Beanstalk (as per previous blog post)
