This paper focuses primarily on the various use cases for AWS Lambda, as well as other tightly integrated AWS services, most notably AWS API gateway and selected AWS database services such as DynamoDB.

Although AWS publicise some of the technical underpinnings of their Lambda service, and some internal implementation details have been discovered by users, many reports are speculative, and because of this, Lambda internals are outside the scope of this document.

An upfront high-level understanding of AWS platform concepts may be helpful, but short explanations or links will be given where possible.
