A solutions architect is optimizing a website for a global musical event. Performances will be streamed live and then offered on demand. Which service will improve performance for both real-time and on-demand streaming?

Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations worldwide. This significantly improves performance for both live and on-demand streaming by delivering content closer to users, reducing latency and increasing transfer speeds. For live streams, CloudFront can ingest the stream and distribute it globally, while for on-demand content, it caches video files for faster access. AWS Global Accelerator improves application availability and performance by directing user traffic to optimal endpoints over the AWS global network, but it doesn't cache content like a CDN. Amazon Route 53 is a highly available and scalable DNS web service; while it can direct traffic, it doesn't handle content delivery or caching. Amazon S3 Transfer Acceleration speeds up large file uploads to S3 buckets, not content delivery to end-users.
