Monolith vs Microservices Explained !! | System Design Tutorial #11

Description

re Microservices always better than a Monolith? Not unless you know how to design them correctly. 🚀 In this System Design Masterclass, we tear down a traditional Monolith and rebuild it using a modern Microservices Architecture. But breaking up your code is only half the battle. How do microservices talk to each other? What is the difference in how they spin up in the terminal? And how do you handle a transaction that spans three different databases? Welcome back to Code Goat! Today, we are using custom interactive animations to visualize the core rules and the 3 most important Microservice Design Patterns used by top-tier tech companies. 📌 What You Will Learn (Timestamps): • 0:00 - Introduction • 2:07 - The Monolith Breaking Point (Visual Crash Demo) • 5:30 - Process Initiation: Monolith (main.py) vs Microservices (Docker) • 7:26 - The Golden Rule: Database Per Service (Avoiding the Anti-Pattern) • 10:57 - Pattern 1: The API Gateway (Routing & Centralized Auth) • 14:25 - Pattern 2: The Strangler Fig (Zero-Downtime Migration) • 16:01 - Pattern 3: The Saga Pattern (Distributed Transactions Visualized) • 20:02 - Top System Design Interview Questions & Answers 💡 Interview Pro-Tip: Never build a microservice architecture with a single, shared database. If you do, you haven't built microservices; you've built a "Distributed Monolith," which gives you all the deployment complexity with none of the isolation benefits! 👇 Binge the FastAPI & Backend Series here: https://www.youtube.com/playlist?list=PL0BwLgm6AcFZhJehdlez2NZtQ9Kn13OsP 💬 Question of the Day: If you are launching a brand new startup tomorrow, are you starting with a Monolith or Microservices?
