An active-active high availability cluster is one of the two most frequently used high availability (HA) cluster configurations. They normally consist of a minimum of two nodes that are running identical services or workloads at the same time. An active-active high availability cluster distributes workloads evenly across a set of nodes to provide load balancing. This way, no single node will get overloaded, and response times are improved. Different types of load balancing algorithms, such as “round robin,” can be used to assign clients to active nodes.
