Correct answer: Deploy the applications in AWS Local Zones by extending the company's VPC from eu-central-1 to the chosen Local Zone..
Why this is the answer
AWS Local Zones allow you to place compute, storage, and other select AWS services closer to end users, providing single-digit millisecond latency for applications that require it. By extending the company's VPC from eu-central-1 to a Local Zone, the applications can run in a location that meets regulatory requirements while still benefiting from the AWS infrastructure and low latency. Deploying in eu-central-1 alone would violate regulations. CloudFront edge locations and regional edge caches are primarily for content delivery and caching, not for hosting entire applications with specific regulatory constraints and compute requirements. AWS Wavelength Zones are designed for ultra-low latency applications that need to be deployed at the edge of 5G networks, which is a more specific use case than simply needing single-digit millisecond latency and regulatory compliance in a general geographic area.
