Which solution will provide the LARGEST improvement in performance?
Create an Amazon Route 53 geolocation routing policy.
Duplicate content in multiple AWS Regions by using S3 Cross Region-Replication.
Use S3 Intelligent-Tiering to move data based on access patterns.
Create an Amazon CloudFront distribution with Amazon S3 as an origin.
Explanations:
Amazon Route 53 geolocation routing helps direct traffic to specific regions but does not directly address the performance issues related to video streaming from Amazon S3, especially in terms of reducing latency or improving streaming quality.
S3 Cross Region-Replication is primarily used to create copies of data across multiple AWS Regions, which may help with data availability and redundancy, but it does not directly improve the performance or speed of video streaming.
S3 Intelligent-Tiering moves objects between storage classes based on access patterns, but it does not optimize for video streaming performance or reduce latency for large-scale requests like those for video clips.
Amazon CloudFront is a Content Delivery Network (CDN) that caches content at edge locations around the world. This dramatically improves video streaming performance by reducing latency and ensuring faster delivery of video clips to users, especially in regions far from the origin S3 bucket.
