  Firecracker is an open source virtual machine monitor (VMM) built by Amazon
  Web Services that uses KVM to create and manage lightweight microVMs. Designed
  for serverless computing and container workloads, it provides the security and
  isolation of traditional VMs with the speed and resource efficiency of
  containers. Firecracker exposes a RESTful management API over a Unix Domain
  Socket, specified in OpenAPI (Swagger 2.0).

      The Firecracker management API is a RESTful public-facing API accessible
      through HTTP calls over a Unix Domain Socket, carrying JSON modeled data.
      It is used to configure and control microVMs, including boot source,
      drives, network interfaces, machine configuration, snapshots, and
      lifecycle actions. Firecracker powers AWS Lambda and AWS Fargate.
