I really like CloudFoundry, it is an amazing project with great potential. So many projects born from within a corporation end up as nothing more than neglected step-children, lagging way too much behind the commercial product they originated from. Vmware has been a lot more open, at least so far, and the OpenSource code is apparently the same code base as they use in production.
The downside of this is that, until the community grows and more developers start contributing, the choice of supported frameworks and services is mostly driven by the needs of the commercial product. A few companies have stepped up to the plate and generously donated their work to the project.
Our first contribution to the project is a CouchDB service; we have pushed it to github and sent a pull request. This is a first draft, a few features are still missing (notably backup/restore/rebalance, as well as quota enforcement); we will be working on these in the coming weeks. Despite these limitations, if you run CF on your own private cloud and your applications needs CouchDB, you can start using testing today.
The reason I'm quite confident with the code is that we are using it to run Chef on CF in staging, with a goal to get it to production in the coming weeks. CouchDB support was the major roadblock; with this service, I'm happy to report it works quite well. We are currently using an external Solr PaaS, but we will be developing a CF service for that as well.
