> I just don't see the advantage to an out of JVM cache when your service is so fast that you only need more than one instance for failover I don't think anyone would advocate that you move to a remote cache. If you can fit your entire app on a single machine, that's great. It's a huge reduction of complexity, and you'll likely be able to get very fast performance like you indicate. You definitely do not need or want a remote cache. These tools are for those that have more data or traffic than a single machine can handle. Things get much more complicated when you move from one computer to two.
