The core challenge is delivering low-latency, synchronized audio and video streams to potentially hundreds of participants while handling varying network conditions, device capabilities, and geographic distribution.
Popular Examples: Zoom, Google Meet, Microsoft Teams, Webex
This system design problem tests your understanding of real-time communication protocols, media streaming architectures, and scaling strategies for latency-sensitive systems.
In this chapter, we will explore the high-level design of a video conferencing system like Zoom.
Lets start by clarifying the requirements.
