Content

• System Design Questions — 10 common interview questions (URL shortener, Twitter feed, YouTube, Uber, WhatsApp, web crawler, Dropbox, notifications, rate limiter, distributed cache) with architecture diagrams, clarifying questions, deep dives, and trade-offs
• Cloud Architecture — Compute, storage, networking, databases, messaging, load balancing, caching, security, observability, resilience patterns, multi-region design
• Databases — SQL vs NoSQL, indexing, replication, sharding, ACID, CAP/PACELC, consistency models, CQRS, event sourcing
• Networking & Protocols — OSI model, TCP/UDP, HTTP versions, TLS, DNS, CDNs, WebSockets, gRPC vs REST vs GraphQL

All content is bundled into the binary — nothing is downloaded at runtime.
