The emergence of cluster technology and the rapid development of IA architecture servers provide new choices for social needs. It is cost-effective, easy to use and maintain, and cluster technology can be used to construct a supercomputer. Its super processing capability can replace the expensive large-scale computer, it has opened up a new direction for high-end applications in the industry.

Cluster technology is a relatively new technology. With cluster technology, you can obtain relatively high performance, reliability, and flexibility at a low cost.

Currently, many of the running supercomputers around the world are implemented using cluster technology.

A cluster is a parallel or distributed system composed of computers connected to each other. These computers work together and run a series of common applications while providing a single system ing for users and applications. From the external perspective, they are just a system that provides unified external services. Computers in the cluster are physically connected by cables, and programs are connected by cluster software. These connections allow computers to use the fault emergency response and load balancing functions, which are not possible on a single machine.

In general, the server cluster system connects multiple servers through a fast communication link. From the outside, these servers are like a server working, but internally, external loads are dynamically distributed to these node servers through a certain mechanism to achieve high performance and high availability of super servers.

Advantages of clusters

High scalability: Server clusters are highly scalable. As demand and load increase, you can add more servers to the cluster system. In such a configuration, multiple servers can perform the same application and database operations.

High Availability: High Availability refers to the ability to prevent system faults or automatically recover from faults without operator intervention. By transferring applications on the faulty server to the backup server, the cluster system can increase the normal running time to more than 99.9%, greatly reducing the server and application downtime.

High manageability: the system administrator can remotely manage one or even one group of clusters, just like in a single-host system.
