System Design

Learn to design large-scale, reliable distributed systems. This visual, diagram-driven course covers fundamentals and estimation, networking, scaling and load balancing, caching and CDNs, databases and storage, consistency and replication, messaging and event-driven design, reliability and resilience, architecture patterns, and real-world case studies (URL shortener, news feed, chat, video platform and more).

Networking & Communication

How distributed components talk to each other: DNS, HTTP/HTTPS, TCP vs UDP, REST, RPC and WebSockets.
3

Scaling & Load Balancing

Vertical vs horizontal scaling, load balancers and their algorithms, and designing stateless services that scale out.
4

Caching & CDNs

Why and where to cache, cache strategies and eviction, the hard problem of invalidation, CDNs and in-memory stores.
5

Databases & Storage

Choosing storage: SQL vs NoSQL, indexing, replication, sharding and partitioning for scale.
6
