The server cluster is the system where you can use 2 or more servers to give a solution in a shorter time. The great first advantages of using this kind of technology is that having two servers working on the same problem defines more efficiency and cutting the solving time.
Many companies are increasing the amount of resource-heavy applications and requiring increasingly massive processing power to manage their systems... yet still rely on obsolete, single computers to do all the work.
For problems of malfunction on some of the computers in the cluster, automatically the work is distributed to the other computers in the cluster. This is more efficiency on problems caused by hardware or any other component problem.
Technology-savvy companies know that a server cluster actually saves them money. So instead of spending their IT budget on many single mainframe systems to process their information separately, they decide to invest in a single powerful central unit to handle all of it at the same time, with more precision and speed.
This is the great solution, because this is more efficient process to solve the speed and management problems of elements and information stored in single servers, processes where need more processing that the one that provides a single and powerful server.
