  title: AWS Lambda Aliases API
  description: The AWS Lambda API enables you to create, configure, and manage Lambda functions, layers, event source mappings, aliases, versions, and function URLs programmatically. Lambda runs your code on high-availability compute infrastructure without provisioning or managing servers, performing all administration of compute resources including capacity provisioning, automatic scaling, and logging. The API version used is 2015-03-31.
