Should You Go For Server Clustering?

Server clustering promises to bring forth the benefits of a united group of servers. It promises to help in areas where single servers cannot. Definitely, there are many benefits of the clustering, with a few limitations. Let’s look at what clustering offers and where it creates problems.

The biggest benefit of server clustering is high availability. With server clustering, one server takes over in case there is a problem with another server. This ensures high availability of applications. Scalability is also a major advantage with clustering. Your growing needs can be accommodated conveniently.

Clustering makes maintenance and management of servers easy. With a group of functional servers, you can choose to shut down one for maintenance while others handle its load. And you can manage and configure cluster servers without a hassle.

Now, let’s look at the problems. The problems are essentially limitations in implementing clustering than problems of the cluster.

You cannot cluster all types of servers, a major limitation of clustering. Also, several applications are not supported by clustering design. So, the clustering may not help every organization.

Another problem with clustering is the cost of setting up a cluster. Some cluster designs are extremely expensive. This does not go well with smaller organizations.

Infrastructure increases manifold with clustering. You have an increased number of server and more hardware to manage and monitor. This adds a management overhead, something not everyone is prepared to handle.

If you want to reap the benefits of the server cluster, you should make sure that your needs will be met adequately before you go for it.
