What is the primary use case for Node Clustering in Node.js?

It is primarily used to build scalable, non-blocking backend architectures where I/O operations are offloaded to the event loop.

How does this integrate with Express or other web frameworks?

It integrates seamlessly as middleware or a core utility within the route handlers, allowing for high-performance request processing.

What are the common pitfalls when implementing Node Clustering?

Developers often forget to handle asynchronous errors or improperly manage memory, leading to memory leaks and blocked event loops.

1The limits of Clustering

Clustering is 'Vertical Scaling' (using all cores on one machine). Eventually, one machine isn't enough. At that point, you switch to 'Horizontal Scaling', deploying multiple identical servers and placing an AWS Application Load Balancer in front of them.
