Stuck in a System Design interview on when to use an API Gateway, Load Balancer, or Reverse Proxy? You're not alone. Knowing the difference—and more importantly, WHEN to use each—is a critical skill that separates senior engineers from junior developers. Every major app from Zomato to Netflix uses this trio to scale and stay reliable. Understanding this architecture isn't just theory; it's a requirement for top DevOps, backend, and system design roles. This is the knowledge that gets you past tough interview questions and proves you can build for the real world. In this video, I demystify these concepts with: ✈️A simple Airport Analogy to make the roles of each component crystal clear. 📈 3 Evolving Scenarios showing how a start up's architecture grows into an enterprise system. ✅ A Clear Comparison of when and why to choose each tool.
