Cache misses and database failure can be detected by the non-database layers and either reported to the user or worked around using replication.

While this architecture works pretty well in general, it isn't as successful in a chat application due to the high volume of long-lived requests, the non-relational nature of the data involved, and the statefulness of each request.

Despite those advantages, using Erlang for a component of Facebook Chat had a downside: that component needed to communicate with the other parts of the system.One of the things I like most about working at Facebook is the ability to launch products that are (almost) immediately used by millions of people.Unlike a three-guys-in-a-garage startup, we don't have the luxury of scaling out infrastructure to keep pace with user growth; when your feature's userbase will go from 0 to 70 million practically overnight, scalability has to be baked in from the start.Glueing together PHP, Javascript, Erlang, and C is not a trivial matter. Thrift translates a service description into the RPC glue code necessary for making cross-language calls (marshalling arguments and responses over the wire) and has templates for servers and clients.Since going open source a year ago (we had the gall to release it on April Fool's Day, 2007), the Thrift project has steadily grown and improved (with multiple iterations on the Erlang binding).
