To add to that, Redis is a TCP server so you can speak to it from multiple processes on multiple machines (and Redis will easily support huge loads)
Its data structure cover a good part of what you'd need with generic data structures, which makes Redis an easy way to do the logic of, say, List intersection of friends common between multiple people, sorted set of goods ranked by their amount, all of this shared with other processes.
Redis also offers pubsub capabilities in two forms:
- A standard PUB/SUB couple which does what you think it does
- Blocking pop on a list for a client, and a push for another client, which will "wake up" the first one with the value.

It's a very versatile swiss knife.
