"a technology that lets you increase the availability of a server, service or application so it does not become a single point of failure."
This description is completely true. We find a simplified definition makes understanding clustering more comprehensible. Clustering strategies are typically used for scaling out performance, load balancing, and recovery. The way we see it, clustering is connecting at least two servers together with one acting as a standby for protection. Clustering solutions are rules based and require custom coding and scripting that define the failover and recovery policy and procedures unique to their environment.
