Understanding the Problem

What is YouTube?

YouTube is a video-sharing platform that allows users to upload, view, and interact with video content. As of this writing, it is the second most visited website in the world 🤯.

Video upload and processing.
Video streaming with multiple quality options (adaptive bitrate streaming).
Video search and recommendations.
Comments and ratings.
User subscriptions and notifications.
Analytics and monetization.

Scale Requirements:

2 billion users.
1 billion hours watched daily.
500 hours of video uploaded per minute.
Global content delivery.
99.9% availability.

How would you design the video processing pipeline (encoding, transcoding)?
How would you implement a global Content Delivery Network (CDN) for low-latency streaming?
How would you generate video recommendations?
How would you handle copyright detection (e.g., Content ID)?
