A company runs a content management application on a single Windows Amazon EC2 instance in a development environment.The application reads and writes static content to a 2 TB Amazon Elastic Block Store (Amazon EBS) volume that is attached to the instance as the root device.The company plans to deploy this application in production as a highly available and fault-tolerant solution that runs on at least three EC2 instances across multiple Availability Zones.A solutions architect must design a solution that joins all the instances that run the application to an Active Directory domain.The solution also must implement Windows ACLs to control access to file contents.The application always must maintain exactly the same content on all running instances at any given point in time.

Which solution will meet these requirements with the LEAST management overhead?

Create an Amazon Elastic File System (Amazon EFS) file share. Create an Auto Scaling group that extends across three Availability Zones and maintains a minimum size of three instances. Implement a user data script to install the application, join the instance to the AD domain, and mount the EFS file share.

Create a new AMI from the current EC2 Instance that is running. Create an Amazon FSx for Lustre file system. Create an Auto Scaling group that extends across three Availability Zones and maintains a minimum size of three instances. Implement a user data script to join the instance to the AD domain and mount the FSx for Lustre file system.

Create an Amazon FSx for Windows File Server file system. Create an Auto Scaling group that extends across three Availability Zones and maintains a minimum size of three instances. Implement a user data script to install the application and mount the FSx for Windows File Server file system. Perform a seamless domain join to join the instance to the AD domain.

Create a new AMI from the current EC2 instance that is running. Create an Amazon Elastic File System (Amazon EFS) file system. Create an Auto Scaling group that extends across three Availability Zones and maintains a minimum size of three Instances. Perform a seamless domain join to join the instance to the AD domain.

Explanations:

Amazon EFS is a good choice for shared file storage across instances, but it does not provide full support for Windows ACLs, which are required for controlling access to the file contents.

Amazon FSx for Lustre is designed for high-performance workloads, typically used with compute-intensive applications. It is not suitable for the use case described, which requires Windows ACLs and file consistency across instances.

Amazon FSx for Windows File Server supports Windows ACLs, is fully integrated with Active Directory for domain joining, and provides shared storage that can be easily mounted across multiple EC2 instances. This is the optimal choice for high availability and fault tolerance.

Amazon EFS does not support Windows ACLs, which are required in this scenario. Additionally, Amazon EFS is not as tightly integrated with Active Directory for seamless domain joining as FSx for Windows File Server.
