Nothing else offers so many benefits like cluster servers do. There is hardly anything that can be called a disadvantage of the cluster servers. Cluster servers are brought in to do away with the limitations of a single server. Let’s look at what cluster servers have to offer.
Reliability and availability
Cluster servers can recover immediately from any kind of failure. They provide a high level of business continuity. Typically, cluster servers help recover from the following kinds of failures:
- Hardware failure
- Software failure
- Site failure
Thus, these servers are always at your service despite problems in one of them.
Growing needs trigger the necessity for growth in the existing system. Cluster servers accommodate growth like no other. You can add more servers to the cluster anytime you need more service.
Easy server maintenance
Maintaining a single server or a bunch of isolated servers is extremely cumbersome because you have to shut down the server completely. This hampers work and may cause extreme inconvenience. Now, imagine the maintenance of cluster servers. When you bring down one server, the other servers continue to be available, providing you service.
Cluster servers are a smart and efficient way of working with servers. Another thing to note is that the servers in a cluster are not isolated but independent. It is only when a server fails, the others share its load to provide you with seamless service.
In one of the following posts, we will discuss the types and uses of cluster servers.
