Running a CouchDB cluster on Amazon EC2

CouchDB is a nearly zero-configuration multi-master document oriented database. It is a awsome product build by an awsome team.
So far I have been using CouchDB like we would have used any other modern Document Datastore: in a centraized fashion. One Server at our premises. For backup purposes we replicated on a second couchdb instance running on our backup server.
Hosting about 300 GB of data a small 2.6 GHz Server with consumer-grade disks we started seeing preformance issues. Also we see latency issues since we are hosting some application at Amazon EC2 “in the cloud” which results an an addiotional 40 ms delay for all queries to our locally hosted server.
