API Gateway Throttling

• Account Limit
  • By default throttles at 10000 request/second across all API
  • Soft limit can be increased upon request
  • Will throw 429 too many request
    • Solution:
      • Exponential Backoff (any AWS service)
  • Time limit: 29 seconds
• Can set Stage Limit & Method Limits for each stage so that if 1 stage is under attack. It doesn't affect the other state
• Or define Usage Plans to throttle per customer

Note: Similar to Lambda Concurrency and Throttling, for API Gateway, if 1 API is overloaded, will cause other API to be throttled
