The ultimate disaster tolerant system is classed as a high availability (HA) system. This configuration is designed to eliminate application downtime by using redundant hardware and networking components and specialized application and operating system software. HA systems can seamlessly route around failures in the computing infrastructure without affecting end-user access to data.
Clustering uses redundancy to minimize the impact of an outage to end users. In a clustering environment, multiple application servers are configured to operate as a single computing unit. Each server is referred to as a cluster node. If an application or node fails, the impacted processing automatically fails over to a surviving node. Clustering is configured for either local failover, using mirroring technologies over a LAN or MAN, or for global outage protection, using replication techniques across a wide-area network (WAN).
Clustering provides continuous 24x7 monitoring with comprehensive fault detection and automated failover to secondary nodes in the cluster. This will ensure service continuity in the event of a failure and eliminate the need for immediate on-site manual intervention.
