Load Sharing for Increased Performance & Outage Redundancy
Clustering is a process of creating platform resilience by logically and physically connecting disparate devices together in such a way as to transfer processes and transactions from one unit to another in the event that a device fails or is utilized beyond its capacity.
Clustering is generally pursued as a vehicle for either load balancing across multiple systems or as a means of preventing a single system outage from disrupting end-user productivity.
