In the modern information system, the server has the most functions,
especially the functions of centralized management and resource sharing. While the
client-side’s functions are relatively simple. It is easy for a Cluster Server to focus on a
small number of high-performance servers, thus the shortcomings due to the lack of
resource sharing and an un-balanced load that exists in the distribution system can be
solved. This ensures resource sharing and a centralized management system, therefore
simplifies the client-side’s functions, ultimately reduces cost.
