CouchBase + Cloud
We are implementing a social shopping site (using Rails 3.2+) similar to Pinterest. We are looking at various NoSQL database options and very much like CouchBase. However, it doesn't seem that CouchBase works on Heroku. Does this mean that if want to use CouchBase, we'd need to migrate to AWS? We don't want to manage servers (even with RightScale), is there another cloud-based hosting service similar to Heroku (that works with CouchBase) that you'd recommend?
