Every technologically-savvy business today makes use of all possible gadgets and applications. The sheer volume of applications used by a business can overwhelm the server that’s playing the host to them. A single server fails to manage the applications efficiently, leading to downtimes or unavailability of certain applications. Now, common sense says that if there was another server available to take over the load, things would be better. It was this common sense that introduced the concept of cluster servers.
A cluster server, therefore, is a group of independent servers brought together to function as one unit in order to ensure higher availability and reliability.
How do cluster servers help your business?
In one of our earlier posts, we discussed the business benefits of cluster servers. Here are the highlights:
- They improve network performance.
- They offer business continuity.
- They provide increased scalability.
- They are easy to maintain.
- They are easy to configure and manage.
Are there any limitations of cluster servers?
With higher availability, better reliability, and increased scalability, you would think that cluster servers have no limitations. However, there are certain things that require you to put some effort from your end.
- Data security: Cluster servers are not equipped to protect your data against threats like viruses. You have to take additional steps to protect your data.
- Server selection: Not all servers can be clustered. You have to be aware of the types of servers you are using.
- Application selection: Not all applications are compatible with cluster servers. However, there are ways to integrate them with these servers.
- Resource sharing: Earlier, the clustered servers used to share resources. If there was a problem in the shared resources, all the servers were affected. However, now, the cluster servers do not share anything, keeping them isolated and unaffected in case of a problem somewhere.
Cluster servers are extremely beneficial to any business that is looking for business continuity. The limitations mentioned above are not limitations in the truest sense; they just require some additional work from the business.
