The performance of a website depends very much on the reliability of the website hosting service that it uses. So, most reputed web hosts like Hostsailor have features that ensure the sites of their clients are up and running 24/7. The most important security feature needed for this is a Redundancy system. This is not only used in Web Hosting but also in all operations where data or information plays a key role in the daily options. The purpose of this article is to investigate in detail redundancy systems; read on to know more about this.

What Is A Redundancy System?

Redundancy systems are methods, tools, and techniques that ensure web hosting or similar services are available when the main infrastructure or the web Server fails. This is made possible by creating a duplicate server when the main server fails. Also, the important information will be there on this mirrored server. There are three basic types of redundancy systems: disk redundancy, redundant servers, and redundant data centers, and they are explained in detail below.

Disk Redundancy:

This is the initial layer of defense that is used as a protection against server failures; it protects against the loss of important information that is required for the functioning of websites. In most cases, this is done by mirroring the information onto a secondary hard drive that is installed on the primary server. The main advantage of doing this is that it helps to switch to the mirrored drive without shutting down the server.

RAID (Redundant Array Of Independent Disks) is a redundancy technology used by reliable web hosting services like Hostsailor hosting. It mainly works by the combination of disk mirroring and stripping techniques. Apart from the disk arrays, another important component of the RAID is the RAID controller. It is a device used for managing the disk arrays; it can either be hardware or software.

Redundant Server:

Redundant servers are the second layer of protection used by web hosts. They set up a secondary server that is configured to mirror the primary server; the secondary server is activated when the primary server fails. The main advantage of doing this is that it minimizes the downtime of websites. Also, it works as a failsafe to web hosting services when physical damages happen to the main server.

Redundant Data Centers:

This is the final layer of redundancy where all the infrastructure and functions of a web hosting data center are mirrored by another data center. Also, this secondary data center will be located at a different location.

We hope that the details shared above gave you a better understanding of redundancy systems used by web hosts.
