What is an application version in Elastic Beanstalk associated with?

An application version in Elastic Beanstalk is indeed associated with an S3 object containing deployable code. When you deploy an application to Elastic Beanstalk, the application’s source bundle, which includes the code and any associated configuration files, is stored as an object in an Amazon S3 bucket. This object represents a specific version of the application.

This allows Elastic Beanstalk to track changes to your application over time, enabling you to roll back to previous versions if needed. Each time you deploy a new version of your application, Elastic Beanstalk creates a new application version linked to a specific S3 object containing the updated code.

The S3 storage mechanism serves as a reliable way to store and retrieve the application versions while ensuring that the deployment process remains consistent and manageable. Thus, the identification and management of application versions through S3 objects is a fundamental concept in the Elastic Beanstalk service.
