When one than one computer work together to perform a task, its known as Clustering.
There are four type of cluster
• Storage
• High availability
• Load balancing
• High performance
Above given type of clustering is basically based on objective of clustering.
Storage clusters provide a consistent file system image across servers in a cluster, allowing the
servers to simultaneously read and write to a single shared file system. A storage cluster
simplifies storage administration by limiting the installation and patching of applications to one
file system. Red Hat Cluster Suite provides storage clustering through Red Hat GFS.
High-availability clusters provide continuous availability of services by eliminating single points
of failure and by failing over services from one cluster node to another in case a node becomes
inoperative. Red Hat Cluster Suite provides high-availability clustering through its High-availability Service Management component.
Load-balancing clusters dispatch network service requests to multiple cluster nodes to balance
the request load among the cluster nodes. Node failures in a load-balancing cluster are not
visible from clients outside the cluster. Red Hat Cluster Suite provides load-balancing through
LVS (Linux Virtual Server).
High-performance clusters use cluster nodes to perform concurrent calculations. A
high-performance cluster allows applications to work in parallel, therefore enhancing the
performance of the applications. (High performance clusters are also referred to as
computational clusters or grid computing.)
