Question #1426

A company is using Amazon CloudFront to deliver static content but experiences high latency for dynamic content served through Application Load Balancers. They want to reduce latency without modifying their existing infrastructure. Which AWS service should they use?

A

AWS Global Accelerator

B

Amazon ElastiCache

C

Amazon Route 53

D

AWS Direct Connect

Explanation

AWS Global Accelerator (Option A) is the correct answer because it improves performance for dynamic content by leveraging AWS's global network backbone. It uses static anycast IP addresses to route user requests to the nearest AWS edge location, which then directs traffic to the optimal ALB over the AWS network, reducing latency.

Other options are incorrect because:
- B. Amazon ElastiCache: Primarily caches data (e.g., databases), which is not suitable for dynamic content that cannot be cached.
- C. Amazon Route 53: While it supports latency-based routing via DNS, DNS caching and lack of real-time path optimization make it less effective than Global Accelerator.
- D. AWS Direct Connect: Establishes private network connections but does not optimize public internet routing to ALBs.

Key Takeaway: Global Accelerator optimizes network paths for dynamic workloads using AWS's backbone, while CloudFront focuses on caching static content at edge locations.

Answer

The correct answer is: A
