QUESTION 13 OF 30

What are the benefits of clustering?

Clustering involves connecting computer resources that perform similar functions and use similar data with each other. The key benefits of clustering include availability and performance. Interviewers at Amazon will ask you about this technology to determine if you have used it before and know how to cluster IT resources. This also indicates that they employ clustering in their environment. When discussing the benefits of clustering, you may also want to bring up its vulnerabilities.

"I have used clustering quite a bit in my previous roles. I especially like this technology when I need to achieve high availability for the resources in a cluster. If one of the systems in a cluster were to fail, the other one would immediately take over, and the processes will continue without interruption. The key to making clustering effective is to ensure that the failover is seamless and that there is no single source of failure on all the systems. This may require locating clustered systems in different locations or providing independent or duplicate power and networking to the systems."
