There's an overlap with what BOSH does. Starts with a stemcell, compiles your packages against it, spins up whole VMs configured with those packages. It also adds monitoring for both VMs and processes. Don't underestimate what you get from a PaaS like Heroku, though. If you're able to stick to 12-factor apps, the lockin is pretty mild -- you should be able to hoist your skirts and move to Cloud Foundry or even OpenShift without too much pain. Disclosure: I work for Pivotal, we work on BOSH and Cloud Foundry. We compete with Red Hat and Heroku.
