description: AWS 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. Lambda runs your code on high-availability compute infrastructure
  and performs all of the administration of the compute resources, including server and operating system maintenance, capacity
  provisioning and automatic scaling, and logging.
