I'm looking for a CMS for use with Appharbor, the issue I've seen with other CMS's is that they store content in the file system which may get deleted between deployments and does not work across multiple nodes (so maybe everything would be stored in the database).
Does anyone have an experience setting up a CMS on Appharbor?
Currently I'm using Umbraco a bit so it anyone has been able to set that up those details would also be helpful.
Other cms's that might work would be Orchard or Composite C1.
Here are some guides that might help you out:
