Nutanix Cloud Clusters (NC2) is the offering specifically designed to extend on-premises private cloud environments into public clouds like AWS and Azure. It allows customers to run the full Nutanix HCI software stack, including AOS, AHV, and other services, on bare-metal instances within the public cloud. This creates a seamless hybrid cloud fabric, enabling application mobility, on-demand capacity bursting, and disaster recovery between the on-prem datacenter and the public cloud without needing to refactor applications. This model unifies management and operations across both environments through a single interface.

A. Nutanix Cloud Security: This refers to security features like Flow Network Security for microsegmentation and threat protection, which secure workloads but do not provide the infrastructure extension itself.

C. Nutanix Kubernetes Engine: This is a service for deploying, managing, and scaling Kubernetes clusters. While it can operate in a hybrid cloud, it is an application platform, not the underlying datacenter extension fabric.

D. Nutanix Data Services: This is a portfolio of storage solutions, including Nutanix Files, Objects, and Volumes. These are components that run on the Nutanix platform, not the solution for extending the platform to the public cloud.
