Introduction

Video conferencing platforms like Zoom have become essential tools for remote work, education, and communication. Developing the architecture for a scalable video conferencing service requires careful system design and planning.

In this comprehensive guide, we will walk through the architectural considerations and system design components needed to build a platform like Zoom. We will outline both functional and non-functional requirements, explore the high-level system architecture, dive deep into the core microservices and data models, and discuss how to optimize for scalability and reliability at scale.

The goal is to provide a blueprint for a robust, low-latency video conferencing system that can handle huge volumes of simultaneous calls. By the end, you will understand how all the pieces fit together into a service like Zoom.
