AWS Service for Global Website Latency Reduction
A company hosts its website on Amazon EC2 instances. The company needs to ensure that the website reaches a global audience and provides minimum latency to users. Which AWS service should the company use to meet these requirements?

Community Insight
The question tests knowledge of Content Delivery Networks (CDNs) versus routing or load balancing, with the common trap being confusion between DNS-based global routing and actual content caching for latency reduction.
Amazon CloudFront is the optimal AWS service to reduce latency for a global audience by caching content at edge locations. This page explains why CloudFront outperforms Route 53 and ELB for static/dynamic web delivery.
Many users choose Amazon Route 53 because it offers global routing, but they fail to realize that Route 53 only directs traffic; it does not cache content or physically bring data closer to the user to reduce latency.

Expert Analysis
Why the Answer Is Correct
Amazon CloudFront is a Content Delivery Network (CDN) that integrates with AWS origin servers like EC2. By distributing content to a network of edge locations globally, CloudFront serves cached assets from the location nearest to the user, which significantly minimizes network latency and improves performance for a global audience.Why the Other Options Are Wrong
Amazon Route 53 is a scalable DNS web service; while it can route users to different regions using latency-based routing policies, it does not cache content, so the request still travels back to the origin. Elastic Load Balancing distributes incoming traffic across multiple targets within a single region or VPC, which does not solve global latency issues. AWS Lambda is a compute service for running code without servers and is not a dedicated solution for delivering website content to end-users.Community Comment Notes
The community consensus strongly supports CloudFront, noting its role as a CDN that caches content at edge locations. One commenter clarified that while Route 53 handles routing, CloudFront is specifically designed to reduce latency by serving content from the nearest point of presence. Another comment emphasized that CloudFront efficiently delivers both static and dynamic content to users worldwide.Exam Strategy
When a question mentions 'global audience' and 'minimum latency' for web content, immediately consider CloudFront. Distinguish between services that route traffic (Route 53) and those that deliver/cache content (CloudFront).
Frequently Asked Questions
Why isn't Route 53 used to reduce latency?
Route 53 routes DNS queries but doesn't cache content. It directs traffic to origins, which may still be far away, whereas CloudFront brings content closer.
Can CloudFront work with EC2?
Yes, you can configure EC2 instances as origins for CloudFront distributions to serve web content via the CDN.
