How to: API Gateway Basics

-	**API Gateway** provides a scalable, secured front-end for service APIs, and can work with Lambda, Elastic Beanstalk, or regular EC2 services.
-	It allows “serverless” deployment of applications built with Lambda.
-	🔸Switching over deployments after upgrades can be tricky. There are no built-in mechanisms to have a single domain name migrate from one API gateway to another one. So it may be necessary to build an additional layer in front (even another API Gateway) to allow smooth migration from one deployment to another.
