Node.js clustering allows you to create multiple instances of your application to take advantage of multi-core systems. It helps improve performance by distributing the load across multiple processes.

What are the benefits of using clustering in Node.js?

The main benefits include improved performance, better resource utilization, and increased fault tolerance. It allows your application to handle more requests simultaneously.

How do I implement clustering in my Node.js application?

You can implement clustering by using the built-in 'cluster' module. You create a master process that forks worker processes to handle incoming requests.

Are there any downsides to using clustering?

Yes, some downsides include increased complexity in your application and potential issues with shared memory between processes.
