With Provisioned Concurrency, functions can instantaneously serve a burst of traffic with consistent start-up latency for every invoke up to the specified scale. Using the AWS Management Console, API, or command line, developers can configure any new or existing function to use Provisioned Concurrency. Customers only pay for the amount of concurrency that they configure and for the period of time that it is configured. Read more about Provisioned Concurrency in the AWS Lambda documentation.
