Distributed Systems Masterclass | CAP, Raft, Quorum, Consistent Hashing, Sagas with Animation

Har bada system distributed hota hai. Is video mein animation ke saath distributed systems ki poori foundation: vertical vs horizontal scaling, network failures aur partitions, CAP theorem (CP vs AP) + PACELC, consistency models (linearizable, causal, read-your-writes, eventual), replication (leader-follower, multi-leader, leaderless), quorums (N, W, R), partitioning + consistent hashing, Raft consensus (leader election + log replication), clocks (Lamport, vector clocks, TrueTime), failure detection + gossip (phi accrual), distributed transactions (2PC, sagas, outbox), delivery semantics + idempotency, aur resilience patterns (timeouts, backoff + jitter, circuit breakers, bulkheads). Perfect for system design interviews and backend engineers.
