DEFINITIONS
|
Cluster
computing
A group of servers and other resources that act like a single system and enable high availability
and, in some cases, load balancing and parallel processing.
Failover clustering
A backup operational mode in which the functions of a system component (such as a processor,
server, network, or database, for example) are assumed by secondary system components when the
primary component becomes unavailable through either failure or scheduled down time.
Load
balancing
Dividing the amount of work that a computer has to do between two or more computers so that more
work gets done in the same amount of time and, in general, all users get served faster.
