The Selection and Study of HA Cluster Software Design

With the rapid spread of network communication technology, the demand of reliability of the network service system is higher and higher for various industries. Any service failure will bring huge loss to the enterprise or individuals. So HA cluster system is increasingly favored by people as an important means of disaster. In this context, this paper analyzed the characteristics and role of HA cluster and the existing HA cluster software. Finally, in terms of optimization of the cluster mode scheme, disk filter way and the monitoring mode program, the corresponding software design scheme selection was put forward.
