Microsoft Windows Cluster Services & Network Load Balancing
A collection of software, the Cluster Services provides automatic recovery from failure and an ability to move workloads for planned maintenance without downtime. It controls all aspects of cluster operations on a cluster system and has closely related, cooperating components: •Node Manager handles cluster membership and watches the health of the other cluster systems.
•Configuration Database Manager maintains the cluster configuration database.
•Resource Manager/Failover Manager makes all resource/group management decisions and initiates appropriate actions, such as startup, restart and failover.
•Event Processor connects the components of the Cluster Service, handles common operations and controls Cluster Service initialization.
•Communications Manager manages communications with all other nodes of the cluster.
•Global Update manager provides a global update service used by other components within the Cluster Service.
•Resource Monitor, while not a part of the Cluster Service, communicates with the Cluster Service via Remote Procedure Calls (RPC). It monitors the health of each resource through callbacks to the resources.
•Time Service maintains consistent time within the cluster.
