Elastic Beanstalk Components

The components that comprise Elastic Beanstalk work together to enable you to easily deploy and manage your application in the cloud. This section discusses those components.


An Elastic Beanstalk application is a logical collection of Elastic Beanstalk components, including environments, versions, and environment configurations. In Elastic Beanstalk an application is conceptually similar to a folder.

Application Version

In Elastic Beanstalk, an application version refers to a specific, labeled iteration of deployable code for a web application. An application version points to an Amazon Simple Storage Service (Amazon S3) object that contains the deployable code such as a Java WAR file. An application version is part of an application. Applications can have many versions and each application version is unique. In a running environment, you can deploy any application version you already uploaded to the application or you can upload and immediately deploy a new application version. You might upload multiple application versions to test differences between one version of your web application and another.


An environment is a version that is deployed onto AWS resources. Each environment runs only a single application version at a time, however you can run the same version or different versions in many environments at the same time. When you create an environment, Elastic Beanstalk provisions the resources needed to run the application version you specified. For more information about the environment and the resources that are created, see Architectural Overview.

Environment Configuration

An environment configuration identifies a collection of parameters and settings that define how an environment and its associated resources behave. When you update an environment’s configuration settings, Elastic Beanstalk automatically applies the changes to existing resources or deletes and deploys new resources (depending on the type of change).

Configuration Template

A configuration template is a starting point for creating unique environment configurations. Configuration templates can be created or modified by using the Elastic Beanstalk command line utilities or API.
