What is a server cluster and what is the difference between a failover cluster and a load-balancing cluster?
What will be an ideal response?
A server cluster is two or more servers configured to operate as a single unit. The most common types of server clusters are failover clusters and load-balancing clusters. A failover cluster is used to provide fault tolerance so that if one server fails, the other immediately takes over its functions with no or little downtime. A load-balancing cluster provides high-performance computing and data access by spreading the workload among multiple computers.
