 - Azure ExpressRoute: Provides high-speed private connections between Azure data centers and on-premises or colocation infrastructure.
 - Azure Virtual WAN (vWAN): Aggregates networking, security, and routing functions together into a single unified Wide Area Network (WAN).
 
+## Use cases and supported scenarios
+
+Learn about use cases and supported scenarios for NC2 on Azure, including cluster management, disaster recovery, on-demand elasticity, and lift-and-shift.
+
+### Unified management experience - cluster management
+
+That operations and cluster management be nearly identical to on-premises is critical to customers.
+Customers can update capacity, monitor alerts, replace hosts, monitor usage, and more by combining the respective strengths of Microsoft and Nutanix.
+
+### Disaster recovery
+
+Disaster recovery is critical to cloud functionality.
+A disaster can be any of the following:
+
+- Cyber attack
+- Data breach
+- Equipment failure
+- Natural disaster
+- Data loss
+- Human error
+- Malware and viruses
+- Network and internet blips
+- Hardware and/or software failure
+- Weather catastrophes
+- Flooding
+- Office vandalism
+
+When a disaster strikes, the goal of any DR plan is to ensure operations run as normally as possible.
+While the business will be aware of the crisis, ideally, its customers and end-users shouldn't be affected.
+
+### On-demand elasticity
+
+Scale up and scale out as you like.
+We provide the flexibility that means you don't have to procure hardware yourself - with just a click of a button you can get additional nodes in the cloud nearly instantly.
+
+### Lift and shift
+
+Move applications to the cloud and modernize your infrastructure.
+Applications move with no changes, allowing for flexible operations and minimum downtime.
+
+## Supported SKUs and instances
+
+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|
+
+Nutanix Clusters on Azure supports:
+
+* Minimum of three bare metal nodes per cluster.
+* Maximum of 28 bare metal nodes per cluster.
+* Only the Nutanix AHV hypervisor on Nutanix clusters running in Azure.
+* Prism Central instance deployed on Nutanix Clusters on Azure to manage the Nutanix clusters in Azure.
+
+## Supported regions
+
+When planning your NC2 on Azure design, use the following table to understand what SKUs are available in each Azure region.
+
+| Azure region | SKU   |
+| :---         | :---: |
+| Australia East | AN36P |
+| East US | AN36 |
+| East US 2 | AN36P |
+| Germany West Central | AN36P |
+| Japan East | AN36P |
+| North Central US | AN36P |
+| Southeast Asia | AN36P |
+| UK South | AN36P |
+| West Europe | AN36P |
