Amazon DynamoDB on-demand is a flexible new billing option for DynamoDB capable of serving thousands of requests per second without capacity planning. DynamoDB on-demand offers simple pay-per-request pricing for read and write requests so that you only pay for what you use, making it easy to balance costs and performance.

When you choose on-demand mode, DynamoDB instantly accommodates your workloads as they ramp up or down to any previously reached traffic level. If a workload’s traffic level hits a new peak, DynamoDB adapts rapidly to accommodate the workload. Tables using on-demand mode deliver the same single-digit millisecond latency, SLA commitment, and security that DynamoDB already offers. You can use on-demand mode for both new and existing tables, and you can continue using the existing DynamoDB APIs without changing code. You do not have to manage any capacity settings for servers, storage, or throughput.
