Amazon API Gateway is a new fully managed service that makes it easy for AWS customers to create, publish, maintain, monitor, and secure Application Programming Interfaces (APIs) at any scale.

With a few clicks in the AWS Management Console, customers can create an API that acts as a “front door” for applications to access data, business logic, or functionality from their back-end services, such as workloads running on Amazon Elastic Compute Cloud (Amazon EC2), or code running on AWS Lambda.

Amazon API Gateway handles all of the tasks associated with accepting and processing billions of daily API calls, including traffic management, authorization and access control, monitoring, and API version management. Amazon API Gateway has no minimum fees or startup costs, and developers pay only for the API calls they receive and the amount of data transferred out.
