We use AWS elastic beanstalk. It's simple to setup a high availability environment. And if needed, you can always access the underlying ec2 instances or elastic load balancer. Jenkins has a plugin that integrates with elastic beanstalk. This makes ci/cd straightforward. There's no extra cost for elastic beanstalk, other than what you'd pay for ec2, s3 and elastic load balancer. We've a starter template with a bunch of .ebextensions scripts that simplify common installation tasks. If your application is a run-of-the-mill web app speaking to a database - elastic beanstalk is pretty much all you need.
