Amazon Web Services (AWS)
Jackrabbit should run without problems on Amazon Web Services.
Google App Engine (GAE)
Jackrabbit does currently not run on the Google App Engine for Java. Problems are:
- GAE doesn't support threads.
- Only one instance of Jackrabbit can run against a repository, this is not the way GAE works.
- There is currently no persistence manager, file system, and data store that runs with GAE (GAE doesn't support writing to files).
If you want to contribute in this area, you may want to have a look at related projects, such as the virtual file system for GAE: http://code.google.com/p/gaevfs
