How to Read This Post Each scenario shows a diagram first, then a short note on why that system fits best. Complexity increases as you scroll. System Strength RabbitMQ Smart broker, routing flexibility, push-based delivery Kafka Immutable log, high throughput, replay from any offset JetStream NATS Lightweight persistence, built-in dedup, low operational cost Level 1 — Foundations 1.

Push-based delivery with acknowledgments. Consumer confirms completion before the broker removes the message. No polling, no offset tracking — just send and ack. ...

In the world of modern software development, the question isn’t whether you’ll need to scale-it’s when. If you’ve ever watched a monolithic application groan under increasing load, fought to deploy a single feature without breaking everything else, or felt trapped by technology choices made years ago, you’re not alone. Let’s explore how event-driven microservices in Go can solve these challenges and build systems that scale gracefully with your ambitions. The Pain of the Monolith Picture this: Your application has grown from a simple CRUD app to a complex beast handling users, notes, notifications, analytics, and more. Every deployment is a nail-biting experience because changing one module might break three others. Your database has become a bottleneck, and adding more servers doesn’t help because everything shares the same database connection pool. Different teams step on each other’s toes, and that cool new technology? Sorry, the entire stack is locked into decisions made in 2015. ...

Backend Communication Current: NATS & JetStream WebRTC All Posts Apache Kafka What is NATS? NATS is a high-performance, cloud-native messaging system designed for microservices, IoT, and edge computing. It provides a simple yet powerful pub/sub model with subject-based addressing, making it ideal for building distributed systems that require fast, reliable communication. ...

Building a real-time note-sharing application is a perfect use case for exploring event-driven architecture. In this comprehensive guide, we’ll build a production-ready system with two microservices (User and Note services) that communicate through NATS, delivering instant updates to a Vue.js frontend. Why Event-Driven Architecture? Traditional request-response patterns create tight coupling between services. When your Note service needs to notify users about changes, you don’t want to make synchronous HTTP calls to every service that cares about notes. Event-driven architecture solves this with loose coupling: ...
