Amazon API Gateway Explained: REST, HTTP, WebSockets and Access Control

Understand Amazon API Gateway on AWS through a learning application's public course catalog, private student progress and live classroom updates. Compare REST, HTTP and WebSocket APIs. Separate API keys from authentication, distinguish private backends from private APIs, and verify caching, browser access, deployment and recovery behavior.
