Elastic Beanstalk allows you to create a new web application using the web application tier or worker tier, update an environment with a newer web application version, or redeploy an earlier uploaded web application version:
- Deploying a new web application is very quick. It creates an underlying required AWS resource and deploys a web application.
- While updating a newer version of a web application, you can perform in-place update. This means that the already deployed web application will be updated with a newer source bundle and may result in restarting the web container or the web application server. As a result, the web application may be unavailable for a while.
- When an environment has more than one EC2 instance, in such a situation, a newer version of a web application can be deployed in a rolling manner. It helps...
