Hi,
I am not getting the exact difference between Fail-overclustering and Load-balancing clustering. Some web sites they are
Fail-over: When one node in your cluster fails, the other takes over. Usually there is a heartbeat program which monitors the other node periodically and the failover happens when something abnormal happens (like say, the node not responding).
Load balancing: You have too much computing to do and would like to share it between the nodes on your cluster. Example: A round-robin DNS server. Each times it receives a request, it gives the next IP in the machine pool so that the other machine handles the request. Though this is not of much use in case of a caching DNS setup, hope you get the idea of load balancing.
giving both are same. I want to know the exact difference between the load balancing,failover & high performance clustering with supported
High performance: Just what it says. Lot of computing power by mixing many machines and using it for computing. Usually for resource intensive operations like those of computational fluid dyanmics, simulations etc. where you havin many parallel operations would benifit. PVM libraries etc. etc. are made use.
One or more of these could be combined together in a cluster.
It would've been good if you searched over the net for these defintions. They don't have much to do with Linux per-se, so technically speaking, these are way too OT here. A question on Beuwolf ... yes! a right topic for discussion on these lists.

Search over the net please.

Software evolves. It isn't designed. The only question is how strictly you _control_ the evolution, and how open you are to external sources of mutations. And too much control of the evolution will kill you. Inevitably, and without fail. Always. In biology, and in software. - Linus
