Once upon a time people would put applications delivered baked into AMIs as a deployment approach. Using a combination of CloudFormation metadata, Cloudwatch Alarms, cfn-init, and other tools applications could be deployed end to end with a single tool immutably.

In a lot of situations infrastructure deployment and configuration management is deeply coupled in the AWS ecosystem (DB changes, Serverless technically is changing your infrastructure definition as application changes).
