To efficiently terminate a Nutanix cloud cluster, the NC2 (Nutanix Cloud Clusters) Console should be used. The NC2 Console provides the necessary tools and interface specifically designed for managing and terminating Nutanix clusters within cloud environments, ensuring a seamless and efficient process.References

Valid CIDR Range:When deploying an NC2 cloud cluster in Azure, a valid CIDR range is necessary to define the IP address space for the cluster and its associated networks. This range ensures that there are no conflicts with existing network configurations and provides sufficient addresses for the cluster resources.

My Nutanix Account:A my.nutanix.com account is required to access Nutanix services and manage NC2 deployments. This account allows administrators to log in, configure settings, and manage their Nutanix environment on Azure.

DNS Server Options:

Cloudflare: A public DNS service that operates over the internet.

Azure: Azure DNS operates within the Azure cloud and does not require VPN or ExpressRoute for connectivity within Azure.

On-premises: Requires a secure connection, such as VPN or ExpressRoute, to be accessible from Azure, as it resides outside the Azure cloud.

Google: Another public DNS service accessible over the internet.

Connectivity Requirements:

On-premises DNS: To integrate on-premises DNS with Azure, secure connectivity (VPN or ExpressRoute) is necessary to ensure seamless and secure communication between the on-premises infrastructure and Azure resources.

Conclusion: An on-premises DNS server would require VPN or ExpressRoute connectivity to be accessible and integrated with the Azure environment.

Account Administrator Role:This role grants the necessary permissions for managing the Azure account, including the ability to open, close, or extend a support tunnel. These capabilities are crucial for the Nutanix Support team to perform diagnostics and troubleshooting efficiently.

Permissions Included:The Account Administrator role encompasses broader account management rights, ensuring that the user can interact with various support and operational aspects of the NC2 environment within Azure.

Jump Host Deployment:A Jump Host provides a secure method to access the NC2 environment when direct connectivity is unavailable. Deploying it in an external VNet allows flexibility in managing network access and security.

VNet Peering:By peering the external VNet (where the Jump Host is deployed) with the VNet containing Prism Central, the administrator can establish a communication pathway. This setup enables secure and controlled access to Prism Central from the Jump Host.

Allowlisting the Azure Subscription:This step ensures that the Azure subscription is recognized and permitted by Nutanix Cloud Clusters (NC2). Without allowlisting, the necessary resources and permissions within the Azure subscription may not be available for NC2, potentially blocking the creation and management of clusters.

Creating an App Registration:This involves setting up an application within Azure Active Directory (AAD) to enable secure communication between NC2 andAzure. The app registration process includes assigning permissions and obtaining necessary authentication credentials, facilitating the interaction and management of Azure resources by NC2.

Flow Gateway Network Security Group (NSG):NSGs control the traffic flow to and from network interfaces associated with VMs and other resources. Configuring the NSG correctly is crucial for ensuring that required traffic is allowed.

Internal NIC Configuration:To allow Native Azure instances in the Prism Central VNet (10.20.0.0/24) to access the web servers in the Tier1 subnet, the internal NIC of the Flow Gateway must be configured to allow traffic from 10.20.0.0/24. This ensures that inbound traffic from these instances is permitted and properly routed to the web servers.

For configuring connectivity between an on-premises datacenter and Azure, the two supported options are:

VPN (Virtual Private Network):Site-to-Site VPN allows you to create a secure connection from your on-premises network to Azure over the public internet using IPsec/IKE protocols.

ExpressRoute:Provides a private connection between your on-premises infrastructure and Azure, ensuring traffic does not traverse the public internet.

Both options provide secure and reliable connectivity, with ExpressRoute offering enhanced performance and security due to its private connection.References

Initial Access: To gain access to the NC2 console, users need to create an account on the Nutanix platform.

My Nutanix Account: Creating a My Nutanix account provides access to the Nutanix console, support, and other resources.

Free Trial and Billing Portal: Starting a free trial or accessing the billing portal can be subsequent steps but require an initial account.

Support Case: Opening a support case is not necessary for initial access but might be needed for specific issues later.

Conclusion: Creating a My Nutanix account is the first step to accessing the NC2 console and other Nutanix services.

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.
