Business Reasons for Clustered Systems

Businesses build clusters of computers to improve performance or availability. Some products and technologies can improve both. However, much clustering activity driving the computer industry today is focused on improving service availability.

Downtime is a critical problem for an increasing number of computer users. Computers have not become less reliable, but users now insist on greater degrees of availability. As more businesses depend on computing as the backbone of their operation, around-the-clock availability of services becomes more critical.
