What is Cluster Computing?

Cluster computing, in its simplest definition, is taking two or more computers and linking them together to work as one. By combining the power of each computer, the result is a much more powerful computer that can keep up with the demands of changing technology.

The reasons for cluster computing are many, including cost reduction. For businesses and companies that have less money to put towards soaring IT costs, having a cluster network of computers can be a much better way of spending resources. In order to afford the processing power provided by the network of computers working together in one powerful unit, businesses would have to spend much more of their budget than combining the power of the computers together.

In addition to the costs, these cluster computers provide a great deal of power when put together. Because single computers have a more difficult time keeping up with the changing needs of hardware, a cluster is better able to handle more complex applications.

Another reason for cluster computing is the need for a system that is more reliable and will not fail. A common use for these clusters would be website hosting. A cluster will spread visitors over all the computers in the cluster in order to spread the load between them. This will prevent an overload, causing a crash that could bring the system down. The computer cluster ensures that the system is always available, which is not possible with a single computer system.

With the advances in technology, cluster computing is allowing businesses to harness the most power from their computers, without having to spend a lot of money on expensive systems. As systems and applications evolve, a single computer just cannot keep up with the changes, which is what makes these clusters so desirable for businesses and companies who are keeping an eye on their budgets.
