You can switch to Pivotal Web Services[0] (disclosure: I work for Pivotal on Cloud Foundry) and get the best of both worlds. PWS is based on Cloud Foundry, which allows routing by path. So as an intermediate step towards decomposing your app into services, you can deploy different copies and have them respond to particular routes. Cloud Foundry uses Heroku's buildpack code, with very minor changes, with additional testing. Your app will stage and run identically. If you decide to switch to docker images, Cloud Foundry can run those too. Cloud Foundry is a complete platform, rather than a collection of components. Test-driven, pair programmed, all that jazz. More mature and production-tested than any alternative that I'm aware of. I think it's awesome, but I'm biased. Feel free to email me. [0] https://run.pivotal.io/ https://run.pivotal.io/
