Open Stack

The real data is stored in the StorageNodes. The end-user never talks to the StorageNodes directly.  

The end-user will use the CloudFiles API to talk to the Proxy Server (or Load Balancers with a Proxy pool in case you have them). The Proxy Server will perform the lookup in the ring to find where the data is located and then will fetch that data from the StorageNode and stream it back to the end-user. 

PS -> In this example above the StorageNode contains the swift account, container and object services  running on it.
