Server Clustering FAQs

What is a server cluster?


How does the cluster of servers work together?
It uses a concept called load balancing where the load of work is distributed (balanced) across servers. In a clustered arrangement, multiple servers act as one unit to accomplish a task.

What are the benefits of server clustering?
Here are the major benefits of server clustering:

  • It is highly scalable. Cluster servers accommodate increasing needs conveniently.
  • It makes maintenance easy. With a group of functional servers, you can choose to shut down one for maintenance while others handle its load.
  • It makes it easier to manage the servers. You can manage and configure cluster servers without a hassle.

What are the limitations of server clustering?
The limitations of server clustering are listed here:

  • It increases the infrastructure. Thus, you have more servers and more hardware to manage and monitor.
  • It is not flexible. Not all types of servers can be clustered. Also, several applications are not supported by clustering design.
  • It is not cost-effective. Server clustering is not only about investing in a few servers but about holding them together with a good server design. Some designs can be very expensive.
