Uber Systems Design

This is an exploration of the technologies, architectures, and patterns behind Uber, detailing the evolution of its system from a Monolithic architecture to a Service-Oriented one. Key areas include their innovative use of the Google S2 Library for mapping, the transition to the DISCO/Dispatch optimization for enhanced performance, and the adoption of various technologies like Node.js for server operations. The module also delves into Uber's use of Redis for caching and queuing, the integration of Apache Kafka for seamless data streaming, and how Cassandra supports their ETA calculations, showcasing the complex technological ecosystem that powers Uber's global operations.
