Which solution will optimize the user experience by providing the LOWEST latency for content uploads?
Upload and store content in Amazon S3. Use Amazon CloudFront for the uploads.
Upload and store content in Amazon S3. Use S3 Transfer Acceleration for the uploads.
Upload content to Amazon EC2 instances in the Region that is closest to the user. Copy the data to Amazon S3.
Upload and store content in Amazon S3 in the Region that is closest to the user. Use multiple distributions of Amazon CloudFront.
Explanations:
While using Amazon S3 and CloudFront can help with content delivery, CloudFront is primarily a content delivery network that caches content but does not optimize upload latency. Uploads through CloudFront are not typically used for uploading content, making this option less optimal for reducing upload latency.
S3 Transfer Acceleration leverages the Amazon CloudFront edge network to speed up uploads by routing them to the nearest edge location, reducing latency significantly. This is particularly beneficial for users uploading content from different geographic locations, thus providing the lowest latency for content uploads.
Uploading content to EC2 instances can introduce additional latency as it requires an extra step of copying data to S3 afterward. This option adds complexity and does not optimize for the lowest latency in uploads, especially as it does not leverage S3’s built-in capabilities.
Although this option stores content in the closest S3 Region, which reduces latency for retrieval, it does not address the upload process directly. Users may still experience latency when uploading content, as it does not utilize any acceleration mechanisms. Multiple CloudFront distributions focus on content delivery rather than optimizing uploads.
