Basically, you're thinking of building a custom PaaS. I'd just use an existing one. PaaSes require an enormous amount of work to make them featuresome and robust. That's all work you're spending that isn't user-facing value. I've worked on Cloud Foundry and so obviously I think it's the bee's knees. You might prefer OpenShift. If you're happy in the public cloud, you can host on Heroku, Pivotal Web Services (my employer's Cloud Foundry instance) or on Bluemix (IBM's Cloud Foundry instance).
