Cluster Management
Cluster management is to monitor and administrate all the computers in a computer cluster. It covers a wide range of functionality, such as resource monitoring, cluster membership management, reliable group communication, and full-featured administration interfaces.
One of the advantages of a cluster system is that it has hardware and software redundancy, because the cluster system consists of a number of independent nodes, and each node runs a copy of operating system and application software. Cluster Management can help achieve high availability by detecting node or daemon failures and reconfiguring the system appropriately, so that the workload can be taken over by the remaining nodes in the cluster.
LVS Cluster Management
Since LVS Cluster is load balancing cluster, the requirement of LVS cluster management is simple, cluster monitoring and administration interface are two major parts.
Cluster Monitoring
The major work of cluster monitoring in LVS is to monitor the availability of real servers and load balancers, and reconfigure the system if any partial failure happens, so that the whole cluster system can still serve requests. Note that monitoring the availability of database, network file system or distributed file system is not addressed here.
Administration Interface
Cluster Management Software
There are many cluster management software in conjuction with LVS to provide high availability and management of the whole system.
