Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsMedium
A financial institution is migrating a critical, high-performance trading application to Azure. The application requires extremely low-latency access to shared storage and supports a distributed file system (DFS) namespace. The solution must provide enterprise-grade availability and performance. Which Azure storage solution should you recommend?
- AAzure Blob Storage
- BAzure Files Premium with SMB
- CAzure Disk Storage (managed disks)
- DAzure NetApp Files
Show answer & explanationAnswer & explanation
Correct answer: D. Azure NetApp Files
Azure NetApp Files provides an enterprise-grade, high-performance file storage service that is ideal for demanding workloads like high-performance computing (HPC) and critical business applications that require extremely low latency and high throughput. It natively supports NFS and SMB, and can be integrated with DFS namespaces.
Why the other options are wrong
- A. Azure Blob Storage is object storage, not a file system, and is not suitable for applications requiring traditional file system access or DFS namespaces.
- B. Azure Files Premium offers good performance but Azure NetApp Files generally provides superior performance for extremely latency-sensitive, high-throughput workloads and better fits advanced DFS requirements.
- C. Azure Disk Storage provides block-level storage for single VMs, not a shared file system solution for multiple instances or DFS namespaces.
Azure NetApp Files
An enterprise-grade, high-performance, metered file storage service for demanding workloads, built on NetApp ONTAP technology.
- Extremely low latency and high throughput.
- Supports NFSv3, NFSv4.1, and SMB3.1.x protocols.
- Ideal for HPC, SAP, and other performance-sensitive applications.
