Application Management for AWS

Currently, the following application management frameworks are available for AWS (excludes third party solutions):

1. AWS Elastic Beanstalk
2. AWS OpsWorks
3. AWS CloudFormation

Details can be found here: https://aws.amazon.com/application-management/

Something they didn't mention in the above web-page is that OpsWorks is a technology acquired in an acquisition, and does not integrate into all of AWS's services yet, the most important being ELB (OpsWorks uses HAProxy). Leaving CloudFormation as the framework of choice if this is an issue.

On the other hand, the downside of CloudFormation is the lack of automated failover.
