 # About Nutanix Cloud Clusters on Azure
 
-The articles in this section are intended for professionals interested in using Nutanix Cloud Clusters (NC2) on Azure.
+In this article, we'll give an overview of the features BareMetal Infrastructure offers for Nutanix workloads.
 
-Email [NC2-on-Azure Docs](mailto:[email protected]) to provide input.
+Nutanix Cloud Clusters (NC2) on Microsoft Azure provides a hybrid cloud solution that operates as a single cloud, allowing you to manage applications and infrastructure in your private cloud and Azure. With NC2 running on Azure, you can seamlessly move your applications between on-premises and Azure using a single management console. With NC2 on Azure, you can use your existing Azure accounts and networking setup (VPN, VNets, and Subnets), eliminating the need to manage any complex network overlays. With this hybrid offering, you use the same Nutanix software and licenses across your on-premises cluster and Azure to optimize your IT investment efficiently.
+
+You use the NC2 console to create a cluster, update the cluster capacity (the number of nodes), and delete a Nutanix cluster. After you create a Nutanix cluster in Azure using NC2, you can operate the cluster in the same manner as you operate your on-premises Nutanix cluster with minor changes in the Nutanix command-line interface (nCLI), Prism Element and Prism Central web consoles, and APIs.

+## Operating system and hypervisor
+
+NC2 runs Nutanix Acropolis Operating System (AOS) and Nutanix Acropolis Hypervisor (AHV).
+
+- AHV hypervisor is based upon open source Kernel-based Virtual Machine (KVM).
+- AHV will determine the lowest processor generation in the cluster and constrain all Quick Emulator (QEMU) domains to that level.
+
+This functionality allows mixing of processor generations within an AHV cluster and ensures the ability to live-migrate between hosts.
+
+AOS abstracts kvm, virsh, qemu, libvirt, and iSCSI from the end-user and handles all backend configuration. Thus users can use Prism to manage everything they would want to manage, while not needing to be concerned with low-level management.
+
+## SKUs
+
+We offer two SKUs: AN36 and AN36P. The following table presents component options for each available SKU.
+
+| Component |Ready Node for Nutanix AN36|Ready Node for Nutanix AN36P|
+| :------------------- | -------------------: |:---------------:|
+|Core|Intel 6140, 36 Core, 2.3 GHz|Intel 6240, 36 Core, 2.6 GHz|
+|vCPUs|72|72|
+|RAM|576 GB|768 GB|
+|Storage|18.56 TB (8 x 1.92 TB SATA SSD, 2x1.6TB NVMe)|20.7 TB (2x750 GB Optane, 6x3.2-TB NVMe)|
+|Network (available bandwidth between nodes)|25 Gbps|25 Gbps|
+
+## Licensing
+
+You can bring your own on-premises capacity-based Nutanix licenses (CBLs). 
+Alternatively, you can purchase licenses from Nutanix or from Azure Marketplace.
+
+## Supported protocols
+
+The following protocols are used for different mount points within BareMetal servers for Nutanix workload.
+
+- OS mount – internet small computer systems interface (iSCSI)
+- Data/log – [Network File System version 3 (NFSv3)](/windows-server/storage/nfs/nfs-overview#nfs-version-3-continuous-availability)
+- Backup/archive – [Network File System version 4 (NFSv4)](/windows-server/storage/nfs/nfs-overview#nfs-version-41)

 ## Responsibility matrix
 
-On-premises Nutanix environments require the Nutanix customer to support all the hardware and software for running the platform.
-For NC2 on Azure, Microsoft maintains the hardware for the customer.
-For more information, see [NC2 on Azure responsibility matrix](nc2-on-azure-responsibility-matrix.md).
+NC2 on Azure implements a shared responsibility model that defines distinct roles and responsibilities of the three parties involved in the offering: the Customer, Microsoft and Nutanix.
+
+On-premises Nutanix environments require the Nutanix customer to support all the hardware and software for running the platform. For NC2 on Azure, Microsoft maintains the hardware for the customer.
