Microsoft Azure Consumption Commitment (MACC):To ensure that the Nutanix licensing costs apply to the MACC, the company needs to make purchases that are recognized by Azure's billing system.

Azure Marketplace Purchases:By purchasing Nutanix licenses through the Azure Marketplace, the costs will be included in the Azure billing and count towards the MACC, thereby leveraging the committed spend.

Azure AD App Registration: When setting up an application registration in Azure AD, specific permissions are required to delegate access.

User Access Administrator Role: This role has the necessary permissions to manage user access to Azure resources, including delegating permissions for app registrations.

Comparison of Roles:

Azure Reader Role: Grants read-only access, insufficient for managing app registrations.

Azure Contributor Role: Allows creation and management of resources but does not include permissions to manage access.

Azure Custom Role: While it can be defined to meet specific needs, the User Access Administrator role is predefined to handle access delegation.

Conclusion: The Azure User Access Administrator role is required to delegate minimum permissions for Azure AD App registration.

Azure Private Endpoint:A Private Endpoint provides secure connectivity to Azure resources by enabling private access through the Azure backbone network. This ensures that the traffic does not traverse the internet, providing enhanced security and performance.

Delegated Subnet:By creating an Azure Private Endpoint for VMs in a delegated subnet, the administrator ensures that the VMs can access Azure resources directly and securely without using the public internet.

Outbound Rule Necessity: For successful cluster deployment, certain outbound connections must be allowed to ensure proper download and configuration of resources.

Critical Destination: "Https://downloads.cloud.nutanix.com/*" is a critical endpoint from which the Nutanix software and updates are downloaded during the cluster deployment process.

Functionality: Ensuring an outbound rule for this destination allows the deployment to fetch necessary files and updates, enabling smooth cluster setup and operation.

Other Destinations:

Https://portal.nutanix.com/: Used for accessing the Nutanix portal, not directly related to deployment downloads.

Https://support.nutanix.com/: Used for support-related tasks, not for deployment-specific downloads.

https://nutanix.dev/ : Related to development and API documentation, not necessary for initial deployment.

Conclusion: Outbound connectivity to "Https://downloads.cloud.nutanix.com/*" is essential for downloading deployment resources.

Purpose of an Organization in NC2:In the NC2 console, an organization serves to manage and segregate clusters based on specific requirements such as departmental needs, project goals, or security policies.

Cluster Management:This segregation allows administrators to apply unique configurations, permissions, and policies to different clusters within the same environment, providing flexibility and control over resource allocation and management.

Equal-Cost Multi-Path (ECMP) Routing:ECMP allows multiple gateways to be used simultaneously for load balancing traffic across multiple paths. In this scenario, ECMP is configured to point to the external subnets in the Nutanix Transit VPC.

Traffic Distribution:All four Flow Gateway instances will be used to distribute the outgoing traffic from the application server based on the ECMP default route configuration. This ensures efficient load balancing and utilization of all available gateway resources.

Bidirectional Traffic:Both sending and receiving traffic will utilize all four Flow Gateway instances, ensuring high availability and performance for network-intensive applications.

No-NAT Path Requirement:For a No-NAT path to function, the external networks must be able to route traffic directly to the Nutanix User VPC without translation.

Externally Routable IP Address:The externally routable IP address ensures that traffic from outside networks can reach the Nutanix User VPC.

Address Space Compatibility:Sharing the same address space as the Nutanix User VPC allows for seamless integration and communication between the external network and the User VPC.

Nutanix NC2 Configuration Guide on No-NAT Networking

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.

Jump Host Deployment:A Jump Host is a secure server used to access other systems in a network. In the context of an NC2 cluster on Azure, it serves as an intermediary for accessing Prism Element and Prism Central.

Flexible Deployment Options:The Jump Host can be deployed in either the Prism Central VNet or an external VNet, providing flexibility in network design and access strategies. This allows the organization to choose the most suitable network for deploying the Jump Host based on their security and connectivity requirements.

IP Forwarding in Azure:Enabling IP forwarding allows the VM to forward network traffic that is not specifically addressed to itself. This is necessary for network devices like the Flow Gateway VM to route traffic correctly.

Network Interface Configuration:Both the Azure portal settings and the VM's operating system must have IP forwarding enabled to ensure proper traffic handling and routing capabilities.
