Hi,

There is a technical requirement to scale a new system easily. This new system consists of three tiered applications (as a batch processors). Each tier will contains at least 2 servers with the same application resides on each server.

So, when one of the tier reaches peak performance, we could extend the scalability easily by adding a new server and the same application to off-load some of the processing loads.

The problem is that one or two of the three tiers require heavy caching (about 3 million records and increasing).

I'm thinking of using distributed caching system to overcome this problem but the new distributed caching system will means an additional point of failure as applications now need to interact with additional caching systems for processing.

I'm currently looking at ncache but just wondering if there is an alternatives to this problem? or is there any other comparable distributed caching system that maybe similar or better than ncache and provide enterprise supports too?

Thanks,

Chen
