## **An Overview of AWS API Gateway**
AWS API Gateway is a potent and sophisticated service within Amazon Web Services (AWS); acting as a fully managed gateway, it empowers developers to build, release, manage, monitor, and secure Application Programming Interface (APIs) at any scale. This service provides a robust, scalable platform for creating APIs that serve as the 'front door' for applications to access data, business logic, or other functionality from backend services.

The service provides capabilities like proxy integration for linking APIs with diverse protocols and formats, as well as robust authorization and authentication features, ensuring secure and seamless access to APIs.
