CF8 Instance Clustering: for performance or failover?

[swood]

In CF8 multi-server you can duplicate an instance (multiple times if you desire) and link them all together as a cluster. Is this purely for fail-over or is there also a performance increase? If it is for fail-over, how would you know if one of your cluster members has failed in some way?

Thanks for any help!

It is for both fail-over and scalability. All cluster nodes can actively participate in sharing the traffic load.
