DynamoDB

A serverless, key-value NoSQL database delivering single-digit millisecond latency for internet-scale applications.

DynamoDB handles the heavy lifting for high-traffic platforms like Lyft and Airbnb: providing a fully managed NoSQL environment that scales horizontally without downtime. It processes over 10 trillion requests per day (hitting peaks of 126 million per second during Amazon Prime Day) across a distributed key-value architecture. Developers use Global Tables for multi-region replication and built-in encryption for data at rest. It maintains sub-10ms response times for petabyte-scale workloads while offering flexible billing models like on-demand capacity to optimize costs.
