   What is Serverless
   Serverless computing is a cloud-computing execution model in which the
   cloud provider runs the server, and dynamically manages the allocation of
   machine resources. Pricing is based on the actual amount of resources
   consumed by an application, rather than on pre-purchased units of
   capacity.

    What are Lambda Functions
    Lambda functions are simple event handlers (typically for HTTP requests)
    which are executed on serverless platform without needs of any virtual
    machine or Docker container.

    Zero Config Lambda Support
    If you want to use Lambdas on zeit put file containing function (with proper
    interface) to `api/`.
    They have native support for Node, Go, Python, and Ruby.
