Question

I have developed an application using AWS services that have been deployed to multiple regions. How do I achieve the best Performance and Availability when users from different locations access my application?

A. Use Route 53 latency based routing for improving performance and Availability.

B. Use a CloudFront distribution for improving performance and Availability.

C. Use Global Accelerator for improving performance and Availability.

D. Use an endpoint of the application directly for accessing it that lies within a user’s Region

Answer 1

Answer: C.

Option A is incorrect.

Route 53 latency-based routing helps select a region that may be relatively faster for the user to send traffic to based on certain factors like internet traffic and proximity to the user's location.

However, the actual route to the destination does not involve providing a fast network path for optimum performance, which is the prime requirement for the scenario.

Latency based routing does not address Availability.

Option B is incorrect.

CloudFront improves performance for both cacheable content (e.g., images, videos) and dynamic content (e.g., API, dynamic site delivery) using edge locations.

Here we are talking about application performance & Availability with a highly reliable, performant network rather than bringing content closer to the user.
