Client accessing the website will be redirected to anyone of the node depending upon configuration of NLB (By default it works on round robin methods) Microsoft Cluster Service (MSCS) Unlike NLB , in MSCS, resource will be online at only one of the nodes at a time . Microsoft Cluster Service is based on the shared-nothing clustering model.
