AWS Certified Solutions Architect Associate SAA-C03 Practice Question
Your client wishes to build a system where their web and mobile platforms can securely request information from a variety of upstream services. This system must support managing developer access, accommodate changes in the structure of requests, and offer mechanisms to limit the number of incoming requests per user. Which Amazon service should they implement to meet these requirements?
The correct answer is Amazon API Gateway because it securely manages API requests, supports developer access control, handles request transformations, and enforces rate limiting. It integrates with AWS services like Lambda and Cognito, making it ideal for managing web and mobile API traffic. The incorrect options lack full API management capabilities - AWS Direct Connect is for private networking, S3 is for storage, and Cognito only handles authentication. Step Functions is for workflow automation, and Lambda executes backend logic but lacks API request management. While some of these services complement API Gateway, none provide a complete solution on their own.
