Introduction
Explore the fundamentals of messaging systems in Node.js and understand core integration patterns such as Publish/Subscribe, task distribution, and Request/Reply. Learn how these patterns enable efficient communication across distributed architectures to build scalable and maintainable applications.
We'll cover the following...
If scalability is about distributing systems, integration is about connecting them. In the previous chapter, we learned how to distribute an application, fragmenting it across several processes and machines. For this to work properly, all those pieces have to communicate in some way and therefore, they have to be integrated.
There are two main techniques to integrate a distributed application: one is to use shared storage as a central coordinator and keeper of all the information, and the other one is ...
