We also did some poc using Memcache and it is like a centralized caching system rather than distributing cache among the nodes. And it is released only very light weight engine and we have to implement our own way to manage it. Anyway, don't you guys have to replicate loca cache among the other node in real time ? Because in that case we have to go either centralize or some notification based local cache synchronizer mechanism. Otherwise we have to find another solution for IS. Because we have that requirement. I think we can try out the Redis also if we think about the the cluster. Anyway we can't think about a distributed cache like Hazelecast again because of it is giving lot of issues.
