What is the name of Amazon's serverless computing service?

Amazon's serverless computing service is AWS Lambda. It is an event-driven Function as a Service platform that runs code without requiring developers to provision or manage traditional servers.

AWS Lambda was introduced on November 13, 2014. A developer uploads a function, selects a supported runtime, and connects it to triggers such as HTTP requests, file uploads, database changes, message queues, or scheduled events. Lambda automatically supplies computing capacity as requests arrive and charges are based largely on usage.

“Serverless” does not mean that no servers exist; AWS operates and manages them behind the scenes. The other choices serve different purposes: SQS is a messaging queue, EC2 provides virtual machines, and Fargate supplies serverless compute for containers. Lambda is specifically designed for short-lived, event-triggered functions.
