Definition - What does Application Clustering mean?
Application clustering typically refers to a strategy of using software to control multiple servers. Clustered servers can help to provide fault-tolerant systems and provide quicker responses and more capable data management for large networks.
Techopedia explains Application Clustering
In application or software clustering, some of the protocols and administrative duties that would have been handled on each individual machine are handled by the joint software program. In other words, the software application is the control unit for the cluster. This is contrasted with a system called hardware clustering, where one individual machine runs the cluster through its operating system.
One of the advantages of application clustering is the scalability of these kinds of systems. With available specialized software, companies can easily set up multiple pieces of hardware that obey the same instructions, and refer to the same sets of information. IT pros refer to a cluster-aware application as an application that can assess systems to assign failover duties or handle delegation for transaction processing. These are kinds of principles supported by application clustering.
