Amazon API Gateway
Amazon API Gateway - is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. It allows you to create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. With API Gateway, you can create robust, secure APIs that act as a "front door" for applications to access data, business logic, or functionality from your backend services.
Key definitions for Amazon API Gateway:
-
HTTP API
A lightweight, low-latency API proxy for HTTP backends, often used for creating modern web applications.
-
REST API
A set of HTTP-based endpoints with predictable URLs to access resources, which represent server-side functionality.
-
WebSocket API
Enables real-time, two-way communication between client applications and the backend.
-
Stage
A named reference to a deployment, which represents different environments such as development, staging, and production.
-
Endpoint
A specific URL path that maps to a backend service.
-
Method
An HTTP method (GET, POST, PUT, DELETE, etc.) that is associated with an endpoint.
-
Integration
The connection between the API Gateway and the backend service that handles requests. Integrations can be HTTP, Lambda, Mock, HTTP_PROXY, or AWS_PROXY.
-
Resource
A part of the API's URL path that represents a specific function or data entity.
