A company wants to migrate its web applications from on premises to AWS. The company is located close to the eu-central-1 Region. Because of regulations, the company cannot launch some of its applications in eu-central-1. The company wants to achieve single-digit millisecond latency.
Which solution will meet these requirements?

A
Deploy the applications in eu-central-1. Extend the company's VPC from eu-central-1 to an edge location in Amazon CloudFront.
B
Deploy the applications in AWS Local Zones by extending the company's VPC from eu-central-1 to the chosen Local Zone.
C
Deploy the applications in eu-central-1. Extend the company's VPC from eu-central-1 to the regional edge caches in Amazon CloudFront.
D
Deploy the applications in AWS Wavelength Zones by extending the company’s VPC from eu-central-1 to the chosen Wavelength Zone.
Explanation:
Explanation
Correct Answer: B
Why Option B is correct:
-
Regulatory Compliance: The company cannot launch applications in eu-central-1 due to regulations. AWS Local Zones are separate from the parent region and can be used when specific regulatory requirements prevent deployment in the main region.
-
Single-Digit Millisecond Latency: Local Zones are designed to provide single-digit millisecond latency to end-users by placing compute, storage, and other AWS services closer to population centers.
-
VPC Extension: Local Zones allow you to extend your VPC from the parent region (eu-central-1) to the Local Zone, maintaining network connectivity and security configurations.
-
Proximity: Since the company is located close to eu-central-1, using a Local Zone in that geographic area would provide the required low latency.
Why other options are incorrect:
Option A: CloudFront edge locations are for content delivery and caching, not for deploying full applications. You cannot extend a VPC to CloudFront edge locations for application deployment.
Option C: Similar to option A, regional edge caches in CloudFront are for caching content, not for deploying applications that cannot be hosted in the main region.
Option D: AWS Wavelength Zones are designed for 5G networks and mobile edge computing, placing AWS infrastructure at the edge of 5G networks. This is not the appropriate solution for general web applications needing regulatory compliance and low latency in a specific geographic area.
Key AWS Services:
- AWS Local Zones: Extend AWS regions to metropolitan areas for low-latency applications
- VPC Extension: Allows seamless connectivity between the parent region and Local Zone
- Compliance: Local Zones can help meet data residency and regulatory requirements
