Elastic Beanstalk AWS 中的环境与应用程序

Question

I recently started using AWS EBS and was confused as to what environment and application is and what is the difference?

Could I use environment to have a development testing and production environment and then have several applications in each environment?

Thanks!

Quoting the docs :

• Application: 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 .

• Environment: An environment is a collection of AWS resources running an application version. Each environment runs only one application version at a time, however, you can run the same application version or different application versions in many environments simultaneously.

Back to your question:

Could I use environment to have a development testing and production environment and then have several applications in each environment?

No. Its the other way around. One application can have multiple environments .

For example. If you application is called: my-first-web-application , then you could have three independent environments in it:

• prod - environment stable serving real life requests, running stable version of my-first-web-application code base.
• dev - development environment when you develop and tests new version of your my-first-web-application code base.
• staging - final testing of a new version of your app, before it gets put into production environment.
