Design YouTube/Netflix System Design Interview

Design a global video streaming platform supporting millions of concurrent users.

Mock Interview with AI

1. Problem Statement

Let's design a video streaming platform like YouTube or Netflix. Walk me through the high-level architecture.

2. Target Architecture (Mermaid)

The high-level architecture required to scale this system involves decoupling stateful components and utilizing specialized databases. Below is the reference architecture:

    A[Uploader] --> B(Video Ingestion)
    B --> C[Transcoding Queue]
    C --> D[Worker Nodes : H.264/H.265]
    D --> E[(Blob Storage)]
    E --> F[CDN Edge Nodes]
    G[Viewer] -->|Adaptive Bitrate| F

3. Key Focus Areas

1
CDN Edge Strategy (Caching hot content)
2
Adaptive Bitrate Streaming (HLS/DASH)
3
Storage Efficiency (Blob storage + Erasure Coding)
4
Upload Pipeline (Chunking & Parallel Encoding)
5
Latentcy vs Throughput trade-offs

Want interactive feedback?

Reading architectures is not enough. Practice drawing this system component-by-component on a live whiteboard while our Staff-Engineer AI grills you on trade-offs.
