SAA-C03 Question 321
Single answerA company has a global user base and runs a web application hosted in a single AWS Region. The application experiences high latency for users in distant locations from the hosting Region. The company wants to improve the performance and availability of the application for all users worldwide, and ensure that user requests are routed to the closest healthy endpoint automatically. Which AWS service should the company use to achieve this?
- A
Amazon CloudFront
- B
AWS Global Accelerator
- C
AWS Direct Connect
- D
Amazon Route 53
Show answer and explanation
Correct answer: B
Explanation
AWS Global Accelerator is the best choice here because it uses the AWS global network to optimize the path between the users and the application, ensuring low latency and high availability. It also provides automatic routing to the closest healthy endpoint based on the user's location, which perfectly aligns with the company's requirements.
- A. Incorrect.
Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations to reduce latency for static and dynamic content. However, it does not provide global traffic routing to multiple endpoints.
- B. Correct.
AWS Global Accelerator is designed to improve global application performance and availability by routing user traffic to the nearest healthy endpoint using the AWS global network. This directly addresses the scenario's requirements.
- C. Incorrect.
AWS Direct Connect is a dedicated network connection service between on-premises environments and AWS. It does not help optimize global performance or route traffic to the nearest endpoint.
- D. Incorrect.
Amazon Route 53 is a DNS service that helps in routing traffic globally. However, it does not automatically route user requests to the closest endpoint or optimize performance like AWS Global Accelerator does.
