Clusters may be configured for various purposes such as web‐based services or computational‐intensive workloads. Based on their purpose, the clusters may be classified into two major types:

 High availability

 Load balancing

When the availability of the system is of high importance in case of failure of the nodes, high‐availability clusters are used. When the computational workload has to be shared among the cluster nodes, load‐balancing clusters are used to improvise the overall performance. Thus, computer clusters are configured based on the business purpose needs.
