The git object data itself goes into a blob-store (like S3); it can be stored without strong consistency. It turns out you only need to keep track of a very small amount of metadata consistently (the refs). Riak, etcd, DynamoDB or the Google Cloud DataStore would all be good choices, I think. I was working on an open-source implementation of Raft as part of this (called barge), but it isn't as reliable as the alternatives above - yet!
