AWS Certified Solutions Architect – ProfessionalDesign Solutions for Organizational ComplexityEasy

A global manufacturing company is planning to migrate its on-premises enterprise resource planning (ERP) system to AWS. The ERP system is a commercial off-the-shelf (COTS) application that requires a highly consistent, low-latency shared file system for its application servers. The company's compliance requirements mandate that all data remain within a single AWS Region. Which AWS storage service should be recommended to meet these requirements efficiently?

  1. AAmazon S3 Standard-IA
  2. BAmazon FSx for NetApp ONTAP
  3. CAmazon EBS Provisioned IOPS SSD
  4. DAmazon EFS Standard
Show answer & explanation

Correct answer: B. Amazon FSx for NetApp ONTAP

Amazon FSx for NetApp ONTAP provides fully managed, highly available, and highly durable shared file storage with support for NFS, SMB, and iSCSI protocols, making it suitable for enterprise applications like ERPs requiring consistent low-latency access and advanced data management features.

Why the other options are wrong

  • A. Amazon S3 is object storage and does not provide a file system interface required by ERP applications for shared access.
  • C. Amazon EBS is block storage, not a shared file system, and cannot be simultaneously mounted by multiple application servers in the way an ERP system would require.
  • D. Amazon EFS is a shared file system but may not always meet the strict low-latency and performance consistency demands of some COTS ERP systems, which often perform better with more specialized file systems like those offered by FSx for NetApp ONTAP.

Amazon FSx for NetApp ONTAP

A fully managed service that provides highly reliable, scalable, and high-performance file storage built on NetApp ONTAP file systems.

  • Supports NFS, SMB, and iSCSI protocols.
  • Offers advanced data management features like snapshots, replication, and data deduplication.
  • Ideal for enterprise workloads such as ERP, SAP, and media processing.

Memory trick: ERP needs ONTAP for consistent shared files.
