A comprehensive system design course covering core infrastructure concepts from single-server setups to production-scale architectures. Topics include SQL vs NoSQL database selection, vertical vs horizontal scaling, seven load balancing algorithms (round robin, least connections, IP hash, consistent hashing, etc.), API styles (REST, GraphQL, gRPC), application protocols (HTTP/HTTPS, WebSockets, AMQP, gRPC), and transport layer protocols (TCP/UDP). Aimed at engineers preparing for system design interviews or seeking to understand how large-scale systems are architected.
