Hi Guys,

Can someone please explain what is the difference between Clustering and Load Balancing.

Thanks,

It is a huge subject but in a nutshell clustering is the ability to increase computing power (throughput) by adding nodes into the cluster. Failover is the ability to detect a failure in an application component and switch to another working component without losing the application functionality.
IMHO both of them are intrinsic with each other because failover depends on a cluster environment to get the ability to choose another node to replace and existing one which has failed.

... and answering your question Load Balancing is the ability to split a load in the same destination into different nodes (servers) in a Cluster.

clustering offers loading balancing and fail over capabilities therefore achieves several service level requirements.
