Unlike in a shared server hosting service, in failover hosting, your web site and all the files associated with it are available on a number of servers. Since identical copies of your account are maintained across multiple enterprise class servers, you can be sure that your outage time will be minimal. The moment there is a problem with your primary Web server, the secondary or tertiary server in the failover cluster will take over. The technology in the failover system will detect the problem and rectify it while the traffic to your web site is immediately is rerouted to the next server in the cluster. Each of these servers is a high end server.
Failover servers are highly recommended in the case of high end, resource hungry web sites. This technology races the reliability factor of your web site to levels that have not been witnessed before. Additionally, this technology also improves the performance of your web site since all the resources of a single server are not shared between websites. With the failover technology, any queries to a database are routed to a dedicated database. This maximizes the resources on the main web server. The resulting improvement in performance and speed is quite apparent in large websites.
If your data is time sensitive and if continual access to your web site is crucial to business, then a failover hosting system can provide you with the security, speed and performance you want. Obviously, the complicated system that is used in a failover hosting comes at a price. Because of the presence of multiple servers, failover hosting is slightly more expensive than traditional hosting services. But for people who are very serious about real-time performance and reliability, the advantage of a failover system is much more important than the cost factor involved.
Failover or failsafe hosting, as the name implies, is a cutting edge hosting technology that ensures minimal to zero downtime for web sites that are hosted on the system. This hosting plan is different from traditional shared server hosting plans.
The failover hosting system is most useful in cases of websites that need to ensure minimal outages.
