AWS Lambda

aid: aws-lambda
name: AWS Lambda
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.

    name: AWS Lambda Extensions API
    description: >-
      The Lambda Extensions API enables you to create extensions that integrate
      with the Lambda execution environment lifecycle. Extensions can run as
      companion processes alongside your function, enabling use cases such as
      capturing diagnostic information, sending telemetry data, and integrating
      with monitoring and observability tools.

    description: >-
      The Lambda Telemetry API lets you collect telemetry data directly from the
      Lambda execution environment. Extensions can subscribe to telemetry streams
      for platform telemetry, function logs, and extension logs to send data to
      custom destinations for monitoring and observability.

      The Lambda Runtime API enables you to use custom runtimes to run functions in
      any programming language. The runtime API provides an HTTP API for custom
      runtimes to receive invocation events from Lambda and send response data
      back within the Lambda execution environment.
