Question 72 of 100 | ← Chapter 11

Q772. 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?

Correct Answer: B. Deploy the applications in AWS Local Zones by extending the company's VPC from eu-central-1 to the chosen Local Zone.

Explanation

To meet the requirements of migrating web applications from on-premises to AWS, achieving single-digit millisecond latency, and complying with regulations that prevent launching applications in the eu-central-1 Region, the most suitable solution is:B. Deploy the applications in AWS Local Zones by extending the company's VPC from eu-central-1 to the chosen Local Zone.AWS Local Zones are an extension of a specific AWS Region and are located in geographic proximity to select metropolitan areas. They enable you to deploy resources, such as EC2 instances, in locations closer to end users, resulting in lower latency. By deploying the applications in AWS Local Zones, you can achieve single-digit millisecond latency while complying with the regulations that prevent launching applications in the eu-central-1 Region.Here's why the other options are not the most suitable choices:A. Deploy the applications in eu-central-1. Extend the company VPC from eu-central-1 to an edge location in Amazon CloudFront:While deploying the applications in eu-central-1 and using Amazon CloudFront edge locations can help improve latency, it may not achieve the single-digit millisecond latency target. Also, it does not address the requirement of not being able to launch some applications in eu-central-1.C. Deploy the applications in eu-central-1. Extend the company VPC from eu-central-1 to the regional edge caches in Amazon CloudFront:Similar to option A, deploying in eu-central-1 and using regional edge caches in Amazon CloudFront can help improve latency but may not meet the single-digit millisecond latency requirement. Additionally, it does not address the regulation that prevents launching applications in eu-central-1.D. Deploy the applications in AWS Wavelength Zones by extending the company VPC from eu-central-1 to the chosen Wavelength Zone:AWS Wavelength Zones are designed to provide ultra-low latency for mobile and 5G applications. While they offer low latency, they are specifically optimized for mobile edge computing scenarios and may not be the optimal solution for general web applications.Therefore, the most appropriate solution to achieve single-digit millisecond latency while complying with the regulations is:B. Deploy the applications in AWS Local Zones by extending the company's VPC from eu-central-1 to the chosen Local Zone.
