We run Memcached behind mcrouter, so multiple cache servers sit behind a single endpoint with high availability built in. It's the exact pattern Radibase itself uses for user sessions across multiple servers — battle-tested on our own platform.

Memcached with mcrouter is tuned for latency-sensitive, in-region session storage. Where you need cross-region cache replication instead, Redis with Dynomite is the better fit — and we'll point you to the right one.
