Global Video Streaming Platform Design

Design a global video-on-demand (VOD) streaming service like Netflix. The system must handle hundreds of millions of users, providing low-latency video playback across varying network conditions. Key areas to address include: 1) The end-to-end video ingestion and transcoding pipeline. 2) A scalable metadata management system for millions of titles. 3) Global content delivery strategies to minimize buffering. 4) High availability for user profiles and watch history tracking under extreme write loads. Discuss the trade-offs between storage costs and playback performance, and how the system remains resilient during regional outages.

Scalable Audio Streaming Platform Design

Design a global music streaming service similar to Spotify. The system must support a library of 100 million tracks and 500 million users. Key challenges include low-latency audio delivery (minimal buffering), efficient search across a massive catalog, and high-throughput tracking of playback events for royalty and analytics purposes. Address how you would handle global content distribution, metadata management, and the trade-offs between consistency and availability in user-generated content like playlists.

Scalable Video Sharing Platform Design

Design a high-scale video sharing platform similar to YouTube. The system must support reliable video uploads from a global user base, asynchronous processing of videos into multiple resolutions and formats (transcoding), and low-latency video streaming. Discuss how you would handle massive storage requirements (PB scale), optimize content delivery via CDNs, manage video metadata, and ensure the system remains highly available even during viral traffic spikes. Address trade-offs between upload latency and processing completeness.

Scalable Video Sharing and Streaming Platform

Design a global video platform similar to YouTube. The system must support high-volume video uploads (500 hrs/min), asynchronous transcoding into multiple resolutions, and low-latency global streaming for billions of users. Focus on the end-to-end lifecycle of a video from upload to playback, detailing the storage strategy for petabyte-scale data, the transcoding pipeline orchestration, and the content delivery architecture. Address challenges related to massive egress bandwidth, metadata scalability, and adaptive bitrate streaming.

Video Streaming Platform (Netflix-scale)

Design a globally distributed video-on-demand (VoD) streaming service. The system must support high-efficiency content ingestion and transcoding, sub-second playback start times via CDN integration, and a resilient metadata management system for millions of titles. Address the challenges of handling high-write viewing history 'heartbeats' and implementing adaptive bitrate streaming to ensure high availability and low latency across varying network conditions.

Global Video Streaming & Sharing System

Design a high-scale video sharing platform similar to YouTube. The system must support reliable video uploads from a global user base, asynchronous processing/transcoding of videos into multiple formats, and low-latency global playback for billions of users. Address how you would handle massive storage requirements, bandwidth costs, and the consistency of video metadata and view counts under high concurrency.
