AWS Serverless Microservices with Patterns and Best Practices - What Is Amazon API Gateway?

Amazon API Gateway is a managed service that simplifies the creation, publication, maintenance, monitoring, and security of APIs at any scale. It acts as a front door for applications to access backend services, supporting both Restful and Websocket APIs. API Gateway is serverless, allowing developers to create APIs that access AWS services or other web services. The video covers the two types of APIs: Restful APIs, which are used in the course, and Websocket APIs, which enable real-time communication. The focus is on using Restful APIs to expose microservice APIs to client applications.
