"Cluster" in the first step of network center and data center"

In today's IT world, we often hear the word "cluster", especially in the field that is widely used in servers and minicomputers. It seems that the concept of cluster has penetrated into all aspects of the IT world. So what is a cluster? Generally speaking, a cluster is a technology that includes connecting at least two systems so that two servers can work as one machine or seem to be one machine. For example, a Web server cluster system generated by two servers is transparent to each end user and looks exactly like a web server. Cluster systems are usually used to improve system stability and data processing capabilities and service capabilities of the Network Center. Various cluster technologies have emerged since the beginning of 1980s, these technologies all come from digital's VAX platform. Because clusters provide high availability and scalability, they quickly become the backbone of enterprise and ISP computing.
The informatization requirements of schools are getting bigger and bigger. Behind a system network and server hardware organization, to build a network center and a data center, we must first cluster the core platform. At present, it should mainly be the library and educational administration system. The server that was just shelved yesterday has become more and more like a data center. We must build a super-good center-Scale Network Data Service Center.
