Description

A Cluster is a group of server machines that host a collection of GIS services. Grouping server machines into a cluster allows you to treat them as a single unit to which you can publish GIS services.

A cluster with more than one server machine provides a level of fault tolerance to the services. At the same time, having more than one machine increases the computing power of your cluster, hence increasing the overall throughput.

A cluster is dynamic with respect to the list of server machines. New server machines can be added to increase computing power without affecting the already running GIS services. You can also remove machines from a cluster and re-assign them to another cluster.
