Why Failover Hosting is Important
If you run an online business or any other website that needs to have a high degree of reliability and stability, you know how disastrous having significant downtime or having to roll back your data can be. It can lead to everything from lost sales to maintenance costs to loss of important records, and the best way to prevent system failure of this kind is to make sure the hosting company you sign up with provides failover hosting. Here, we’ll take a quick look at how failover works, and why it is important to any website that needs to keep its data stable and intact at all times.
Failover hosting essentially consists of two separate servers that have a “heartbeat” cable running between them. The main server, which normally hosts the website and stores data, sends electronic signals to the secondary server. Should the main server fail, these signals will cease, thus causing the secondary server to immediately take over the task of hosting the website. Each server is updated simultaneously, so that they always have the same type of data. This is called redundancy, and it is used to keep one server from getting ahead of the other and thus losing track of data.
Failover hosting can have a number of other benefits and features. Occasionally, there is a third server called a “spare parts” server, which is used to decrease downtime while failback is being performed. Failback refers to the process of restoring the original server to its normal capacity after it has failed. The second server may also be able to send a page to a technician or support center in order to get someone on the scene quickly to failback the original machine. Using failover in your hosting service is an excellent way to cut down on the amount of time your site is down during maintenance or technical problems, and will ensure that you don’t lose any important information in the case of any technical problems.
There are a lot of things that you will want to avoid losing, particularly if you run a business online, and failover hosting is simply the best way to prevent that. There are several ways to use failover, as it might be automated or be initiated by a human technician, but in the end it serves as the only way to not only back up data but increase overall downtime.
