Dedicated Server Cluster

Why Dedicated Server Cluster Hosting?

In a nutshell, dedicated server cluster hosting involves building and deploying multiple servers in a customized clustering environment for high-availability, mission critical applications.

Load Balancing of Dedicated Server Hosting

With a load-balancing, dedicated server cluster, all of the servers act as one unit. A software or computer service acts as the manager, distributing jobs evenly across all of the dedicated servers, sometimes with more than one hosting server handling the same task. If something should happen to one of the dedicated servers in the cluster, the manager will simply hand that server’s assigned tasks off to another dedicated server.

Benefits of Dedicated Server Cluster


When a dedicated server cluster is in use, more than one dedicated server handles all of the tasks. If your needs grow beyond what you currently have available, another dedicated server is simply added to the cluster. There are no service interruptions and down time because the dedicated servers in the cluster will continue running tasks. The new server is simply added into the route configuration on the primary dedicated server.


Server clusters allow for application failover. With failover, when an application component stops working, for whatever reason, a copy of the component takes over and finishes the task. In the case of a server cluster, there are copies of the application components on more than one server in the cluster. If one stops working, the manager simply hands the application off to the next available copy.

Easier Maintenance

Server clusters allow for easier maintenance of the servers. If there is a problem with a server, it can be disconnected from the cluster by either disconnecting the network cable or turning off the power. Once disconnected, the server can be repaired or replaced. Meanwhile, the other servers in the cluster continue to run processes as long as at least one server from the cluster remains online.

Rolling Upgrades

Server clusters make it easier to upgrade servers or install patches. As with any other maintenance, the servers in the cluster will continue the necessary processes, even if only one server from the cluster remains. Upgrading does not require downtime with a server cluster setup.

Easier Administration

Server clusters typically are set up with a primary server that handles routing and security functions, while the other servers handle the actual operations. This separates web service administration from security and routing administration. Security and routing administration, which is the most frequent, only involves the primary server, simplifying the process and reducing overhead.


Server cluster hosting can also improve functionality of applications if they are too much for one server to handle effectively. For example, an Exchange system with several thousand users would create a mail load that is too big for one server. With a server cluster, the load can be split up so that the Exchange functions as well as one that is much smaller.

Regardless of the type of web presence you are building, whether e-commerce or a static, informational site, using dedicated server cluster hosting can be beneficial. Dedicated server cluster hosting helps prevent unwanted downtime and ensures that your site is accessible to your customers. In the long run, faster performance and greater accessibility will translate to more traffic and higher sales.  Check out our most Frequently Asked Questions on Dedicated Server Hosting.
