System Design 201: Real-World Architectures#

Welcome to System Design 201. In this course, we move from theory to practice. We will take the building blocks you learned in System Design 101 and use them to architect complete, production-ready systems.

What You Will Build#

  1. High-Throughput Systems: A URL Shortener and a Rate Limiter.
  2. Real-Time Systems: A Chat Application like WhatsApp.
  3. Data-Intensive Systems: A Video Streaming Service like YouTube.
  4. Distributed Consistency: A Distributed Counter.

Prerequisites#

  • Completion of System Design 101 (or equivalent knowledge).
  • Understanding of basic components: Load Balancers, Databases, Caching, Queues.
