Answer: Amazon CloudFront
## Explanation **Amazon CloudFront** is the correct choice because: 1. **For real-time streaming**: CloudFront supports live streaming using RTMP protocol and can cache live streaming content at edge locations, reducing latency for global viewers. 2. **For on-demand streaming**: CloudFront is a Content Delivery Network (CDN) that caches video content at edge locations worldwide, providing low-latency access to on-demand videos. 3. **Global audience**: CloudFront has a global network of edge locations that deliver content with low latency to users worldwide. 4. **Comparison with other options**: - **AWS Global Accelerator** (B): Optimizes network paths for TCP/UDP traffic but is not specifically designed for streaming content delivery. - **Amazon Route 53** (C): A DNS service that routes users but doesn't cache or accelerate content delivery. - **Amazon S3 Transfer Acceleration** (D): Accelerates uploads to S3 but doesn't optimize streaming delivery to end users. CloudFront is specifically designed for content delivery including streaming media, making it the best choice for improving performance of both real-time and on-demand streaming to a global audience.
