The system configuration is shown below:Scalable operation
In scalable operation, apache is operated on all nodes. A client can use the HTML data on the shared disk by connecting to either node.
Standby operation (cold-standby)
In standby operation, a cluster system consists of an operational node and standby nodes. On the operational node, apache, a logical IP address and shared disks are active. On the standby nodes, these resources are inactive. In the event of a failure, production operation is switched to one of the standby nodes, and the resources in this standby node are activated. The client can connect to the running node using the logical IP address without configuration changes.
