DynamoDB Failed 5 Times. Then It Hit 89M req/sec.

DynamoDB handles 89 million requests per second at single-digit millisecond latency. But it took 5 generations of engineering to get there — each one fixing a failure the last one couldn't handle. From consistent hashing to Paxos replication, from split-for-heat to global admission control — this is the full animated story of how DynamoDB evolved into a system that processes 89M req/sec.
