AWS Certified Cloud Practitioner (CLF-C01)- Amazon API Gateway

The video provides an overview of Amazon API Gateway, a service that helps developers create, publish, maintain, monitor, and secure APIs. It acts as a front door for applications to access backend services like EC2, Lambda, and S3. The video uses a hotel comparison website example to illustrate how API Gateway facilitates API calls and data retrieval. It also covers features like traffic management, authorization, caching, and monitoring. The benefits of API Gateway, including integration with AWS services, security features, and performance enhancements, are discussed.
