System Design Fundamentals helps software engineers learn the core ideas behind designing large, complex systems. You’ll cover essential building blocks—caching, load balancing, data partitioning/sharding, proxies, and more—and learn how these pieces fit together to meet real-world requirements like scalability, reliability, and performance.

By the end of the course, you’ll have a clear framework for approaching system design problems and the practical tools to reason about trade-offs and bottlenecks. Whether you’re preparing for system design interviews or strengthening your day-to-day architecture skills, this course gives you the fundamentals you can build on for more advanced topics.
