Topic 1 Question 287
A company wants to migrate a Windows-based application from on premises to the AWS Cloud. The application has three tiers: an application tier, a business tier, and a database tier with Microsoft SQL Server. The company wants to use specific features of SQL Server such as native backups and Data Quality Services. The company also needs to share files for processing between the tiers.

How should a solutions architect design the architecture to meet these requirements?
- Host all three tiers on Amazon EC2 instances. Use Amazon FSx File Gateway for file sharing between the tiers.
- Host all three tiers on Amazon EC2 instances. Use Amazon FSx for Windows File Server for file sharing between the tiers.
- Host the application tier and the business tier on Amazon EC2 instances. Host the database tier on Amazon RDS. Use Amazon Elastic File System (Amazon EFS) for file sharing between the tiers.
- Host the application tier and the business tier on Amazon EC2 instances. Host the database tier on Amazon RDS. Use a Provisioned IOPS SSD (io2) Amazon Elastic Block Store (Amazon EBS) volume for file sharing between the tiers.

- It is B: A: Incorrect> FSx file Gateway designed for low latency and efficient access to in-cloud FSx for Windows File Server file shares from your on-premises facility.
  
  B: Correct> This solution will allow the company to host all three tiers on Amazon EC2 instances while using Amazon FSx for Windows File Server to provide Windows-based file sharing between the tiers. This will allow the company to use specific features of SQL Server, such as native backups and Data Quality Services, while sharing files for processing between the tiers.
  
  C: Incorrect> Currently, Amazon EFS supports the NFSv4.1 protocol and does not natively support the SMB protocol, and can't be used in Windows instances yet.
  
  D: Incorrect> Amazon EBS is a block-level storage solution that is typically used to store data at the operating system level, rather than for file sharing between servers.

  Data Quality Services: If this feature is critical to your workload, consider choosing Amazon RDS Custom or Amazon EC2. https://docs.aws.amazon.com/prescriptive-guidance/latest/migration-sql-server/comparison.html
