Systems Design of Netflix

Introduction

Netflix. It’s more than just a streaming service; it’s a cultural phenomenon. But have you ever paused (pun intended) to think about the colossal tech machinery running behind those binge-watching sessions? From starting as a DVD-by-mail service to becoming the world's leading streaming service, Netflix has seen exponential growth. This didn't just happen with catchy shows alone. Netflix’s journey is a masterclass in evolving architecture to handle massive growth. In this section, we'll dive into how Netflix evolved its systems to ensure a seamless experience for millions, all while ensuring scalability, availability, and top-notch performance.

Netflix's prime challenge wasn’t just streaming a movie; it was about streaming thousands of movies and shows to millions of users globally, each with their own preferences, device specifications, and network capabilities. While you cozy up with popcorn, Netflix is working in overdrive, ensuring your stream doesn't buffer, the quality is top-notch, and oh, suggesting that next binge-worthy show. Let's explore the architectural magic behind this.

When you think about Netflix, it's not just about streaming "Stranger Things" or "The Crown." It's about ensuring that every episode, every scene, and every frame is available at your fingertips. This requires a robust backend, capable of handling millions of requests, delivering content tailored to your preferences and doing all of this without a hiccup. And as Netflix grew from a niche service to a global powerhouse, its systems had to evolve. The goals? Scalability to accommodate its ever-growing user base, availability to ensure you can watch your favorite shows anytime, and performance to make sure the experience is smooth.
