Step-by-Step Solution
Solution:
Step 1: Identify API Gateway features for scalability and security
API Gateway offers throttling to limit request rates, authentication to secure access, and monitoring to track usage and errors.Step 2: Compare with direct backend exposure
Directly exposing backend services lacks these managed features, making scaling and security harder.Step 3: Evaluate incorrect options
Direct backend exposure is faster and more secure than API Gateway. is false because direct exposure is less secure. API Gateway automatically writes backend code for you. is false; API Gateway does not write backend code. Backend services cannot handle API requests without API Gateway. is false; backend can handle requests but less efficiently.Final Answer:
API Gateway provides throttling, authentication, and detailed monitoring out of the box. -> Option AQuick Check:
API Gateway = security + scaling + monitoring [OK]
Quick Trick: API Gateway adds security and scaling features easily [OK]
Common Mistakes:
- Assuming direct backend is more secure
- Thinking API Gateway writes backend code
- Believing backend cannot handle requests alone
