Question

A company is building a new web application that serves static and dynamic content from an API. Users will access the application from around the world. The company wants to minimize latency in the most cost- effective way. Which solution will meet these requirements MOST cost-effectively?

Accepted Answer

**Option A** satisfies every requirement:

1. **Static content → S3 + CloudFront**: S3 stores static assets (HTML, CSS, JS, images). CloudFront caches these at 400+ edge locations worldwide, dramatically reducing latency for global users.

2. **Dynamic content → API Gateway HTTP API + CloudFront**: API Gateway HTTP API is the most cost-effective API Gateway type (up to 71% cheaper than REST API). By placing it as a CloudFront origin, dynamic API responses benefit from CloudFront's global edge network — even uncached requests are routed over AWS's optimized backbone network, reducing latency.

3. **Single CloudFront distribution with multiple origins**: CloudFront uses **origin routing via cache behaviors** (e.g., `/api/*` → API Gateway, `/*` → S3). This is a clean, unified architecture und
