Benefits of Clustering

Clustering provides the feature of improving system efficiency and enhancing system performance. Some of the main benefits of clustering are as follows:

• Clustering provides parallel processing, which means that more than one core can work together on a single source code. One part of the code will run on the master core, and the other part will be executed on the other cores present in the cluster.
• Clustering provides load balancing to machines and software, which means the load that should be on a single core will be divided into multiple cores, so the whole load will not be on a single core; it will be divided into multiple cores.
• Clustering provides resource utilization; it will help to utilize the other cores of the processor that are available to use, which leads to proper resource utilization.
• Clustering provides you with energy efficiency because the cores that are free or not working are being utilized, and so here we are saving energy.

In this article, we are going to learn about clustering through Node.js. Clustering is a process through which we can use multiple cores of a computer simultaneously. Like JavaScript, which is a single-threaded language, the code of JavaScript will run only on a single core if you have more than one core installed on your machine. So clustering is the process through which we can enhance the performance of our software using multiple cores of the machine at the same time.
