AWS managed services are known to support 3 application deployment methods-
a. Immutable-
In this method, applications are directly burnt into AMI. They deploy a freshly new infrastructure every time there is a new release.
b. Manual-
In this method, you have the freedom to deploy your own infrastructure and make other modifications by getting administrative access.
c. Deployment Automation-
With this method, your applications will be automatically installed and configured on your current infrastructure.
