A company is planning to deploy a web application that will serve a global user base. The application needs to deliver low latency content to users and accommodate regional data sovereignty requirements. Which AWS infrastructure deployment approach facilitates the company's needs by capitalizing on the relationship among AWS Regions, Availability Zones, and edge locations?
Using a single Region to host the application and database instances, without leveraging edge locations for content delivery
Setting up an S3 bucket in one Region to serve static content globally, without distributing copies through a content delivery network (CDN)
Utilizing edge locations to host the main database and compute resources, while using Regional data centers for backup purposes only
Deploying web servers in multiple Availability Zones within a single Region, configuring a CDN to cache content at edge locations, and replicating data across Regions to meet sovereignty requirements
Hosting the entire application on a single EC2 instance in one Availability Zone for all global users, relying on that one instance for low latency delivery
The most appropriate infrastructure deployment approach for the described scenario involves the use of AWS Regions to adhere to data sovereignty requirements as Regions are physical locations around the world where AWS clusters data centers. The company should also utilize Availability Zones within these regions to ensure application resilience and high availability since they are designed to be isolated from failures. Additionally, edge locations should be used to cache content closer to end-users to reduce latency, achieved through services like Amazon CloudFront.
