To be honest, we don't 100% cover what you're looking for in an ideal world, as we have our own deployment engine.
That being said, our deployment engine is pretty powerful (in terms of supported AWS infra resources), and it's based on AWS CloudFormation (with a fallback to making native AWS SDK calls to speed up the deployment, when doing the whole CF deployment procedure is not needed). And we do that in a way so that you don't have to worry about CloudFormation drift, or any unexpected surprises.
