Question #804
Which AWS service is optimized to reduce latency by caching and delivering content through a global network of edge locations?
Amazon CloudFront
AWS Elastic Load Balancing
Amazon API Gateway
AWS Direct Connect
Explanation
Amazon CloudFront is the correct answer because it is specifically optimized as a CDN to cache static and dynamic content at AWS edge locations worldwide. This reduces latency by serving content from the nearest edge location to end-users.
Other options are incorrect because:
- B. AWS Elastic Load Balancing (ELB) distributes traffic across targets within a region but does not cache content globally.
- C. Amazon API Gateway manages API traffic and supports regional caching, but lacks global edge caching capabilities.
- D. AWS Direct Connect establishes private network connections to AWS, unrelated to content delivery or caching.
Key Points:
1. CloudFront uses edge locations to cache content closer to users.
2. CDNs like CloudFront are designed to reduce latency for global audiences.
3. Other services focus on load balancing, API management, or network connectivity, not global content delivery.
