***CORRECT*** C. Use Amazon CloudFront with a custom origin pointing to the on-premises servers. Amazon CloudFront is a content delivery network (CDN) that speeds up the delivery of static and dynamic web content, such as HTML, CSS, JavaScript, images, and videos. By using CloudFront, the company can distribute the content of their website from edge locations that are closer to the users in Europe, reducing the loading times for these users. To use CloudFront, the company can set up a custom origin pointing to their on-premises servers in the United States. CloudFront will then cache the content of the website at edge locations around the world and serve the content to users from the location that is closest to them. This will allow the company to optimize the loading times for their European users without having to move the backend of the website to a different region.

C. This solution leverages the global network of CloudFront edge locations to cache and serve the website's static content from the edge locations closest to the European users. A. Hosting the website in a single region would still result in increased latency for European users accessing the site. B. Moving the website to S3 and implementing Cross-Region Replication would distribute the website's content across multiple regions, including Europe. S3 is primarily used for static content hosting, and it does not provide server-side processing capabilities necessary for dynamic website functionality. D. Using a geoproximity routing policy in Route 53 would allow you to direct traffic to the on-premises servers based on the geographic location of the users. However, this option does not optimize site loading times for European users as it still requires them to access the website from the on-premises servers in the United States. It does not leverage the benefits of content caching and edge locations for improved performance.

CloudFront is the most suitable for reducing latency here.

C for sure

Ans C... I was going for D, then I saw (CookieMr, 1yr 2mth ago) "Route 53 geoproximity routing policy in does allow you to direct traffic to the on-premises servers based on the geographic location of the users - BUT does not optimised site loading times for European users as it still requires them to access the website from the on-prem servers in the US."

C is the appropriate answer

Immediate solution is C A: Requires site migration so won't be immediate B: Dynamic site cannot work from S3 D: Geoproximity routing policy finds a server close to the user so this makes no sense C: Not ideal but best option given the "immediate" requirement as CloudFront is a CDN so it will cache whatever is possible as close to the user giving best performance in this case (i.e. when compared to other options)

C. Use Amazon CloudFront with a custom origin pointing to the on-premises servers.

The key reasons are: CloudFront can cache static content close to European users using edge locations, improving site performance. The custom origin feature allows seamlessly integrating the CloudFront CDN with existing on-premises servers. No changes are needed to the site backend or servers. CloudFront just acts as a globally distributed cache. This can be set up very quickly, meeting the launch deadline. Other options like migrating to EC2 or S3 would require more time and changes. CloudFront is an easier lift. Route 53 geoproximity routing alone would not improve performance much without a CDN.

C is best solution.

Within few days you can not do more than using CloudFront

Option C

C is correct answer

CloudFront = CDN Service

C. S3 Cross region Replication minimize latency but also copies objects across Amazon S3 buckets in different AWS Regions(data has to remain in origin thou) so B wrong. Route 53 geo, does not help reducing the latency.

C is correct
