AWS Lambda Operators
==================================================

`AWS Lambda <https://aws.amazon.com/lambda/>`__   is a
serverless, event-driven compute service that lets you
run code for virtually any type of application
or backend service without provisioning or managing servers.
You can trigger Lambda from over 200 AWS services and software as a service (SaaS) applications,
and only pay for what you use.

Airflow provides an operator to invoke an AWS Lambda function.
