The document describes a load balancer distributing requests across multiple lighttpd web servers running fastcgi applications. It also shows databases for user profiles and messages with memcached caching. Messages are enqueued into a message queue processed by worker processes and inserted into a replicated message database with a slave for high availability. Cached messages from previous lookups are stored in memcached for improved performance.
