Your company's user base is globally distributed. They are deploying a web application with a need to minimize latency for end-users in different countries and also want to maintain high availability and disaster recovery. Which of the following setups would best meet these requirements?
You selected this option
Establishing one AWS Direct Connect connection for each user location worldwide
You selected this option
Deploying the application across multiple Availability Zones within a single Region
You selected this option
Utilizing Amazon Route 53 and Amazon CloudFront for a multi-Region, latency-reducing presence
You selected this option
Using AWS DataSync to synchronize data across multiple Regions
Creating a multi-Region architecture with Amazon Route 53 and Amazon CloudFront will address their requirements effectively. Amazon Route 53 can help route the users to the nearest deployment to reduce latency and improve disaster recovery by rerouting traffic in case of a region failure, while Amazon CloudFront can cache the content close to the users around the world. This ensures lower latency for a globally dispersed user base. Utilizing multiple Regions alone does not address latency to the same extent, as there is no mention of a content delivery network (CDN). Creating additional Availability Zones within a single Region will improve high availability but does not consider global latency or disaster recovery across regions or countries. AWS Direct Connect increases the data transfer rate between on-premises systems and AWS but doesn't directly address global latency for end-users.
