Azure DocumentDB is a NoSQL document database service designed from the ground up to natively support JSON and JavaScript directly inside the database engine. It’s the right solution for applications that run in the cloud when predictable throughput, low latency, and flexible query are key. Microsoft consumer applications like MSN use DocumentDB in production to support millions of users.
