dynomite is an open-source Erlang implementation of Amazon’s Dynamo, a distributed key-data storage that strives for high availability. At Amazon, this system is used from everything from shopping carts to product catalogs, and handles millions of requests along with hundreds of thousands of transactions.

The project has some great resources including a guide to get started talking to the system through Ruby on their wiki. Fork away and read up on how it works if you’re interested.
