I use it for caching, temporary content, pubsub, and distributed locking. It's been particularly useful in load balancers / proxies for authorization, managing csrf, and tracking session activity to auto-log out users. I do this with OpenResty. In async job or internal rpc systems, I use pubsub and streams for distributing work, ensuring exactly once processing, and getting results back to the caller.
