Windows Clustering

Windows clustering is a strategy that uses Microsoft Windows and the synergy of independent multiple computers linked as a unified resource - often through a local area network (LAN). Clustering is more cost-effective than a single computer and provides improved system availability, scalability and reliability. Windows clustering also provides a single client name, a single administrative interface and data consistency across all nodes.

Windows clustering is also known as Microsoft clustering technology or Microsoft cluster server.

Windows clustering includes three primary components:
  • Server clustering: Maintains data integrity and provides failover support.
  • Network load balancing (NLB): Addresses bottlenecks resulting from front-end Web services.
  • Component load balancing (CLB): Addresses the unique scalability and availability needs of middle-tier applications.
Windows clustering guards against three types of failure: Application/service, system/hardware and site failures, which may result from power outages, connection failures or disasters.
