System Design Concepts

System Design Concepts

TCP/UDP, DNS, HTTP, reverse proxy, load balancing, CDN, WebSockets, and API protocols

Storage & Databases

Indexes, RDBMS internals, SQL vs NoSQL, Redis, Cassandra, S3, caching, and full-text search

Database sharding — hash, range, directory strategies and cross-shard operations

Leader-based replication, read replicas, replication lag, and consistency models

Distributed Systems

CAP, PACELC, consistency models, idempotency, distributed locking, leader election, gossip, and quorum

Consensus & Coordination

Two-Phase Commit, Raft consensus, log replication, and safety guarantees
