Simply put, a cluster (cluster) is a group of computers that provide users with a set of network resources as a whole. These individual computer systems are the nodes (node) of the cluster. An ideal cluster is that the user never realizes the nodes at the bottom of the cluster system, in their view, the cluster is a system, not multiple computer systems.     And the administrators of the cluster system can add and revise the nodes of the cluster system at will. Below on the server commonly used three cluster software to do a comparative analysis of the introduction: 1 ...
