Default Route for Internet Traffic: By setting the default route of 0.0.0.0/0 for the Nutanix User VPC pointing to the external-NAT network, all internet-bound traffic from the desktops will be routed through the Azure NAT Gateway, conserving bandwidth on the ExpressRoute connection.

On-Premises Route: Setting a specific route to the on-premises subnet for the Nutanix User VPC pointing to the external-No-NAT network ensures that traffic destined for on-premises resources bypasses the NAT Gateway and utilizes the ExpressRoute connection, optimizing the use of network paths.

NAT Based Network: A NAT-based network is designed to provide inbound and outbound internet access while obscuring the internal private addresses. This setup uses Network Address Translation (NAT) to map internal IP addresses to a public IP address, ensuring that internal addresses are not exposed to the public internet.

Security and Connectivity: NAT provides a layer of security by hiding internal IP addresses and allowing controlled access to external resources. This configuration is well-suited for VMs that need to communicate with servers on the public internet while maintaining the privacy of their internal network addresses.

Flow Gateway VMs : Flow Gateway VMs are used to manage and route network traffic within an NC2 on Azure cluster, ensuring sufficient bandwidth for workloads.

Scalability : To ensure enough available bandwidth, multiple Flow Gateway VMs can be deployed.

Maximum Limit : The highest number of Flow Gateway VMs that can be deployed within an NC2 on Azure environment is 6, providing the necessary capacity to handle high traffic volumes and ensure optimal performance.

Conclusion : Deploying up to 6 Flow Gateway VMs ensures adequate bandwidth for NC2 workloads.

When the administrator notices that the VMs cannot reach resources outside the network, even by IP address, it is likely that a default route was not configured for the external subnet. The default route is essential for directing traffic from the VMs to external networks. Without it, the VMs will not know how to route traffic to external destinations, which leads to connectivity issues.

Azure Resource Providers : To prepare an Azure subscription for NC2, specific resource providers must be registered to enable necessary services and resources.

Required Providers :

Microsoft.Network : This provider is essential for networking functionalities, including virtual networks, subnets, and other network resources necessary for NC2 deployment.

Microsoft.Nutanix : This provider is specifically required for integrating and managing Nutanix resources within the Azure environment.

Other Providers :

Microsoft.HybridNetwork and Microsoft.HybridCompute : These are not specifically required for NC2 but might be relevant for other hybrid or extended network configurations.

Conclusion : Registering both "Microsoft.Network" and "Microsoft.Nutanix" ensures that all necessary network and Nutanix-specific resources are available for NC2 deployment.

Getting Started with Nutanix NC2

To verify that the NC2 specialist has access to the necessary organizations for troubleshooting the issue, the administrator should:

Confirm that the Support Authorization on the organization is set to Full Access . This ensures that the NC2 specialist has the required permissions to access the necessary resources and perform the necessary actions to resolve the issue.

Providing login credentials or adding the specialist as an admin user is not recommended due to security and privacy concerns. Ensuring the specialist is assigned the correct RBAC role is another valid approach but confirming the support authorization directly ensures they have the needed access.

In the scenario presented, the NC2 cluster was initially deployed with two Flow Gateways (FGW1 and FGW2) in HA. After adding four bare-metal nodes and additional workloads, two more Flow Gateways (FGW3 and FGW4) were added to handle the increased bandwidth for north/south traffic. Given the configuration, the existing workloads can utilize all available Flow Gateways (FGW1, FGW2, FGW3, and FGW4) for No-NAT (routed) traffic paths. This setup allows for Equal Cost Multipath (ECMP) routing, distributing traffic load across all Flow Gateways.

Scenario Analysis :

A. Connectivity between sites already provides encryption : Using VTEP in this scenario is advantageous because VTEP does not inherently provide encryption. If encryption is already provided, VTEP can be effectively used without additional security concerns.

D. Multiple remote Availability Zones exist to add to the same VTEP-based extended Layer 2 subnet : VTEP is well-suited for scenarios where multiple remote Availability Zones need to be connected to the same extended Layer 2 subnet. This allows for efficient management and seamless connectivity across different zones.

Scenarios B and C :

B. Only one remote Availability Zone exists that needs the subnet extended : This scenario does not leverage the strengths of VTEP, as it is better suited for multiple zones.

C. Connectivity between sites already does not provide encryption : Using VTEP without existing encryption is not ideal as VTEP itself does not encrypt the traffic.

Conclusion : VTEP is advantageous when encryption is already in place and when multiple remote zones need to be connected to the same extended subnet.

NC2 on Azure Deployment : Deploying Nutanix clusters in Azure involves configuring various components, each needing appropriate network isolation and configuration.

Components and vNets :

Bare-metal instance : Requires its own vNet to ensure proper network isolation and performance.

Prism Central : Needs a dedicated vNet to manage and monitor the Nutanix environment, ensuring it has the required network access and isolation.

Azure Load Balancer : Does not require its own vNet but needs to be associated with the appropriate vNet where services are deployed.

Virtual Network Gateway : Is used for VPN connections but does not necessitate a separate vNet; it operates within an existing vNet.

Network Isolation : Providing separate vNets for Bare-metal instances and Prism Central ensures optimal performance and management capabilities.

Conclusion : Both Bare-metal instances and Prism Central require their own vNets in the NC2 on Azure deployment.

To troubleshoot the error shown in the exhibit where Azure credentials are not valid and the creation of the resource group failed, the administrator should:

Verify that the Azure AD App registration has been correctly configured, especially the Client Secret.

Ensure that the Client Secret is valid, has not expired, and matches what has been entered in the configuration.

This step is crucial because an invalid or expired Client Secret would prevent the validation of Azure credentials and the creation of necessary resources.
