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. We cover message publishing, queue subscriptions, fan-out patterns, filtering, retries, DLQs, idempotency, and how to avoid duplication or message loss in distributed systems.
You’ll also see real-world architecture patterns used in ecommerce, SaaS, and large-scale applications — including async processing, background tasks, event propagation, chaining microservices, and clean architecture design for serverless.
This video is perfect for backend engineers, cloud developers, and anyone building microservices the right way. By the end, you'll have a complete blueprint for designing event-driven Node.js microservices using SNS + SQS like a professional.
