Answer 1

Amazon API Gateway acts as a proxy to the backend operations that you have configured. Amazon API Gateway will automatically scale to handle the amount of traffic your API receives. Amazon API Gateway does not arbitrarily limit or throttle invocations to your backend operations and all requests that are not intercepted by throttling and caching settings in the Amazon API Gateway console are sent to your backend operations.
