System Design at Scale

Master distributed systems architecture. Learn scalability, sharding, caching strategies, and the CAP theorem to design high-traffic applications.

System Design is the gatekeeper for Senior and Staff engineering roles. This course teaches you to architect systems that handle millions of users. You will master core concepts like Load Balancing, Database Sharding, Caching patterns (Write-through vs Write-back), and Asynchronous Messaging. We dissect real-world architectures of companies like Netflix, Uber, and Twitter to understand trade-offs in Consistency, Availability, and Partition Tolerance (CAP Theorem).
