Reverse Proxy vs Load Balancer vs API Gateway: Everything you need to know

Confused about the difference between a Reverse Proxy, Load Balancer, and API Gateway? In this video, you'll learn exactly how modern backend systems handle traffic, scale applications, route requests, protect servers, and power microservices architectures used by companies like Netflix, Amazon, and other large-scale platforms. Most developers can define these terms individually, but very few truly understand when to use a Reverse Proxy, when to use a Load Balancer, and when an API Gateway becomes necessary. By the end of this video, you'll be able to read system design diagrams with confidence and understand how real-world cloud architectures are built. 🚀 In this video you'll learn: ✔ What a Load Balancer actually does ✔ How traffic is distributed across servers ✔ Reverse Proxy explained with real examples ✔ SSL Termination, Caching, Security & Rate Limiting ✔ API Gateway explained simply ✔ API Gateway vs Reverse Proxy ✔ Reverse Proxy vs Load Balancer ✔ Load Balancer vs API Gateway ✔ Microservices Architecture Fundamentals ✔ Backend Scaling & High Availability ✔ System Design Concepts for Developers ✔ Modern Cloud Architecture Explained Whether you're preparing for frontend interviews, backend interviews, system design interviews, software engineering roles, or simply trying to understand how scalable applications work, this video will help you build a strong mental model of modern infrastructure. 📚 Topics Covered: Reverse Proxy Tutorial API Gateway Tutorial Load Balancer Tutorial NGINX Explained HAProxy Explained Envoy Proxy Explained Kong API Gateway Backend Architecture Distributed Systems System Design Basics Microservices Architecture High Availability Scalability Traffic Routing Request Forwarding Cloud Computing AWS Architecture Concepts Software Engineering Fundamentals If you've ever looked at an architecture diagram and wondered: "Why is there a Reverse Proxy here?"
