Explanation

Amazon CloudFront is AWS's Content Delivery Network (CDN) service that caches content at edge locations worldwide. When configured with EC2 instances as the origin source, CloudFront:

• Distributes content globally: CloudFront has edge locations in major cities worldwide, bringing content closer to end users
• Reduces latency: By caching content at edge locations, users get faster response times regardless of their geographic location
• Handles global traffic: Automatically routes users to the nearest edge location with cached content

Why other options are incorrect:

• Option A: EC2 instances cannot be deployed directly in edge locations - edge locations are for caching, not compute
• Option B: Using different regions still requires users to connect to specific regions, which may be far from their location
• Option D: Different AWS accounts don't address the latency issue - the physical location matters more than account structure

CloudFront is specifically designed for this use case - serving global content with minimal latency by leveraging AWS's global edge network.
