The customer wants to deploy storage in the public cloud. The goal is to leverage native cloud infrastructure as well as NetApp's enterprise-grade…

Cloud Volumes ONTAP is NetApp's software-defined storage (SDS) solution that runs the ONTAP data management software natively in public clouds like AWS, Azure, and Google Cloud. It integrates directly with native cloud infrastructure, using cloud block storage for performance tiers and object storage for capacity tiers. This architecture provides the requested enterprise-grade NetApp features, including high availability (HA) configurations for resilience, robust security features, and storage efficiencies like deduplication and compression for cost-effective performance. It is the only solution listed that meets all the customer's requirements for a NetApp-powered storage deployment within a public cloud environment.

A. StorageGRID: This is a software-defined object storage solution. While it can be deployed in the cloud, it does not provide the multi-protocol (file and block) capabilities inherent to ONTAP.

B. BlueXP observability: BlueXP is the unified management control plane for NetApp's hybrid cloud data fabric. It is used to deploy and manage services like Cloud Volumes ONTAP, but it is not the storage solution itself.

D. AFF: All-Flash FAS (AFF) is a series of physical, on-premises hardware appliances. It is designed for data centers and cannot be deployed as a native service in the public cloud.

1. NetApp Documentation, "What Cloud Volumes ONTAP is": "Cloud Volumes ONTAP is a software-only storage appliance that runs the NetApp ONTAP storage software in AWS, Azure, or Google Cloud... It provides enterprise-class data management features for your cloud storage... High-availability for business continuity... Storage efficiencies like data compression, deduplication, and thin provisioning reduce your storage footprint." (docs.netapp.com/us-en/bluexp-cloud-volumes-ontap/concept-what-it-is.html)

2. NetApp Product Data Sheet, "Cloud Volumes ONTAP": "NetApp® Cloud Volumes ONTAP® is a software-only storage service that brings the #1 enterprise data storage operating system to the big three public clouds: Amazon Web Services (AWS), Microsoft Azure, and Google Cloud... It leverages the underlying cloud provider’s block storage and object storage..." (netapp.com/pdf.html?item=/media/7238-ds-3750.pdf, Page 1, "Overview" section)

3. NetApp Product Page, "NetApp AFF All-Flash Storage": This page describes AFF systems as physical hardware appliances ("all-flash systems") for on-premises deployment, confirming they are not a public cloud solution. (netapp.com/data-storage/all-flash-storage/aff-a-series/)

4. NetApp Product Page, "NetApp BlueXP": This page defines BlueXP as a "unified control plane" used to "Deploy, manage, and automate your hybrid multicloud," confirming it is a management tool, not the storage service itself. (netapp.com/bluexp/)
