SAP-C02 Question 454
Select 2Your company has a global e-commerce platform with users primarily located in North America, Europe, and Asia. The platform experiences high latency issues due to the geographical distance between users and the origin servers hosted in a single AWS Region. You need to design a solution to reduce latency for end users while maintaining high availability and fault tolerance. Which combination of AWS services should you use to achieve this?
- A
AWS Global Accelerator to optimize routing and improve latency for global users
- B
Amazon CloudFront to cache content closer to users and reduce load on the origin servers
- C
Amazon Route 53 for DNS-based routing with geolocation policies
- D
AWS Direct Connect to establish private connections between the users and AWS
- E
Amazon S3 Transfer Acceleration to speed up uploads from users to S3 buckets
Show answer and explanation
Correct answers: A, B
Explanation
To reduce latency for global users accessing a central AWS-hosted application, AWS Global Accelerator and Amazon CloudFront are the most effective services. AWS Global Accelerator optimizes routing for user traffic, ensuring requests are directed to the nearest and healthiest endpoint. Meanwhile, CloudFront caches content at edge locations, delivering it closer to end users and reducing load on the origin servers. Together, these services provide a comprehensive solution for improving application performance and availability globally.
- A. Correct.
AWS Global Accelerator helps improve the performance and availability of your global applications by routing traffic through the AWS global network and selecting the optimal edge location, making it a suitable choice for reducing latency.
- B. Correct.
Amazon CloudFront is a globally distributed content delivery network (CDN) that caches content at edge locations close to users, significantly reducing latency and decreasing the load on the origin servers.
- C. Incorrect.
Amazon Route 53 provides DNS-based routing options, including geolocation, but it does not directly reduce latency or cache content, making it less effective in this scenario.
- D. Incorrect.
AWS Direct Connect is useful for establishing private, low-latency connections between on-premises networks and AWS, but it is not designed to address latency for global end users.
- E. Incorrect.
Amazon S3 Transfer Acceleration improves upload speeds for S3 objects over long distances, but it does not address the broader latency issues for a global e-commerce application.
