SOA vs Microservices vs Monolith | Architecture Explained Simply #04

Description

In this video, we compare Monolithic Architecture, SOA (Service-Oriented Architecture), and Microservices to help you understand how they differ and when to use each one. This is Part 02 of the Microservices Mastery series. We break down the concepts in a simple, practical way—no fluff, just real-world understanding. In this video: What a monolith is and where it works best What SOA is and how it evolved How microservices differ from SOA Key trade-offs: scalability, deployment, and complexity Which architecture you should choose and why Ideal for developers, architects, and anyone preparing for system design interviews. 🔥 What You’ll Learn in This Course ✅ Microservices vs Monolith vs SOA ✅ Service decomposition & DDD fundamentals ✅ API Gateway & Service Discovery ✅ Event-Driven Architecture & Messaging ✅ Saga Pattern, CQRS & Event Sourcing ✅ Resilience, Security & Observability ✅ Docker, Kubernetes & CI/CD basics ✅ Production best practices & 12-Factor App All concepts are explained with practical Node.js examples and real-world use cases. 👨‍💻 Who This Course Is For * Node.js developers (Beginner → Intermediate) * Backend engineers moving to microservices * Developers preparing for system design interviews * Engineers building scalable distributed systems 🧠 Prerequisites * Basic Node.js & JavaScript * REST API fundamentals * Basic database knowledge * Command line basics 📦 Course Structure Overview ``` 01.
