  A manufacturing company has a critical application that runs at a remote site that has a slow internet connection. The company wants to migrate the workload to AWS. The application is sensitive to latency and interruptions in connectivity. The company wants a solution that can host this application with minimum latency. Which AWS service or feature should the company use to meet these requirements?

  A. Availability Zones

  B. AWS Local Zones

  C. AWS Wavelength

  D. AWS Outposts

  Correct Answer: D

  AWS Outposts is designed for workloads that need to remain on-premises due to latency requirements, where customers want that workload to run seamlessly with the rest of their other workloads in AWS.

  AWS Local Zones are a new type of AWS infrastructure designed to run workloads that require single-digit millisecond latency, like video rendering and graphics intensive, virtual desktop applications. Not every customer wants to operate their own on-premises data center, while others may be interested in getting rid of their local data center entirely. Local Zones allow customers to gain all the benefits of having compute and storage resources closer to end-users, without the need to own and operate their own data center infrastructure.

  (D) AWS Outposts would be the best fit here. Since the client is migrating only the workloads on AWS while (B) AWS Local Zone wants to get rid of hosting its on-prem data center.
