There are a variety of redundant solutions that can range from “hot sites” used to protect geographic failures to clustered servers that offer failover protection as well as enhanced system performance. Some failover options require intervention to switch production between systems, but most can be fully automated as a true “High Availability” solution.

As with anything else, there are pros and cons that come with each configuration… Selecting the right solution is a balance of the company requirements, associated cost, and manpower.

The concept to span services among multiple servers was originally designed for high capacity services such as mail, However large networks and remote access increased the demand to include all types of application servers including support for legacy programs.

KNS has proven experience in all availability solutions and we have worked with networks of all sizes with just about all the availability techniques in use today. We also offer hosting services in our secure collocation facilities for redundant servers or cold storage backups.

When Combined with other solutions such as data storage and a backup system, High Availability can provide complete disaster protection.
