API Gateway

Create interfaces for your existing AWS apps and backend services

Essentials

• Fully managed service to create and manage your own APIs for your apps

• API Gateways act as a "front door" for your applications, allowing access to data/logic/functionality from your back-end services

Main Features

• Build RESTful APIs with:

  • Resources

  • Methods (i.e. GET, POST, PUT)

  • Settings

• Deploy APIs to a "Stage" (different envs: i.e. dev, beta, production)

  • Each stage can have it's own throttling, caching, metereing, and logging

• Create a new API version by cloning an existing one.

  • You can create and work on multiple versions of an API (API version control)

• Roll back to previous API deployments

  • History of API deployments are kept

• Custom domain names

  • Custom domain names can point to an API or Stage

• Create and manage API keys for access AND meter usage of the API keys through Amazon CloudWatch Logs

• Set throttling rules based on the number of requests per second (for each HTTP method)

  • Request over the limit throttled (HTTP 429 response)

• Security using Signature v.4 to sign and authorize API calls

  • Temporary credentials generated through Amazon Cognito and Security Token Service (STS)

  • Workflows related to controlling billing through AWS!

Benefits

• Ability to cache API responses

• DDoS protection via CloudFront

• SDK generation for iOS, Android, and JavaScript

• Supports Swagger (popular framework of API dev tools)

• Request/response data transformation (i.e. JSON IN to XML OUT)
