An Effective Way to Handle Failover in Client-Server Architecture

Failover is the operational procedure of exchanging amongst essential and optional frameworks or framework (a server, processor, system, or database) in case of downtime. Such downtime could be brought by either planned support, or unpredicted framework or segment disappointment. In either case, the question is to make adaption to internal failure – to guarantee that mission-basic applications or frameworks are always accessible, paying little heed to the sort or degree of the blame. Because of the different reasons for Client Server Architecture failures, taking care of failover must be vital. So, various types of Failover solutions are implemented to handle failover in client-server architecture. In this, we analyse causes of failures and various solutions of failover and based on that try to handle failover with pacemaker and High Availability (HA) in centos Linux with database replication techniques
