Cluster (Servers)

Advanced IT Terms | Noun

the computing equivalent of a congregation of alligators, a cauldron of bats or a murder of crows. A cluster of servers is a group of servers working together as one system to provide users with high availability through a high degree of redundancy. That is, if one server fails, another node in the system can take its place. In a cluster, only one node will be working at a time, with the others being in stand-by mode, ready to replace it. Replacement is possible because all nodes in a cluster are attached to a shared storage system.


“And here you can observe a cluster of servers humming peacefully in the remote cable jungle.” 

“Nice David Attenborough impression.”
