NodeJS Microservices with SNS & SQS: A Complete Guide

Building reliable, scalable, and fully event-driven microservices requires more than just writing Node.js functions — you need a strong communication layer. In this complete guide, we walk through how to build production-ready Node.js microservices using AWS SNS & SQS, the most powerful messaging combo in the serverless ecosystem.

You’ll learn how SNS handles pub/sub broadcasting, how SQS ensures message durability, and how to connect both with Lambda-backed microservices.
