AWS Lambda is an advance compute service that lets users run code without managing or provisioning servers. Users can also build here serverless applications which are composed of functions and triggered by events and automatically deployed using AWS CodeBuild and CodePipeline. The AWS Lambda is used to:

  • Build on-demand and smaller applications which are responsive to events and new information.
  • Support native Linux executables operate securely by calling them out from a supported runtime.
  • Execute code in response to triggers.
  • Real time file and stream processing.
  • Perform data sorting, filtering, validation and other changes for data in a DynamoDB table and then load them to another data store.
