Component load balancing (CLB) is a Microsoft Windows Server OS series technology that enables the efficient and even balancing of services requests in a COM/COM+ based computing architecture. CLB is designed to provide availability, reliability and scalability of components or objects that are essential for real-time application based transactions or processes.
CLB is implemented in distributed computing architectures in which an application is deployed over one or more servers. The entire CLB process works on the collaboration of a CLB configured load balancing router and application server(s).
The CLB router receives all application requests from the Web/front end server. These requests are then routed between the connected application server cluster. The CLB router is responsible for managing a routing table, which includes network paths, to implement server clustering, load processing on each server and the entire interprocess/device communication. This helps identify the current status of an application server and balance the network/request load across the cluster.
The Web or front end server also may be configured to provide CLB services and directly interact with the application server cluster.
