Operator Nexus Azure resources prerequisites

  • Article

To get started with Operator Nexus, you need to create a Network Fabric Controller (NFC) and then a Cluster Manager (CM) in your target Azure region.

Each NFC is associated with a CM in the same Azure region and your subscription.

You need to complete the prerequisites before you can deploy the first Operator Nexus NFC and CM pair. In subsequent deployments of Operator Nexus, you'll only need to create the NFC and CM after reaching the quota of supported Operator Nexus instances.

Install CLI Extensions and sign-in to your Azure subscription

Install latest version of the necessary CLI extensions.

Azure subscription sign-in

Azure CLI 
  az login
  az account set --subscription $SUBSCRIPTION_ID
  az account show

Note

Your account must have permissions to read/write/publish in the subscription

Resource Provider registration

Ensure access to the necessary Azure Resource Providers for the Azure Subscription for Operator Nexus resources. Register the following providers:

Azure 
az provider register --namespace Microsoft.Compute
az provider register --namespace Microsoft.ContainerService
az provider register --namespace Microsoft.ExtendedLocation
az provider register --namespace Microsoft.HybridCompute
az provider register --namespace Microsoft.HybridConnectivity
az provider register --namespace Microsoft.HybridContainerService
az provider register --namespace Microsoft.HybridNetwork
az provider register --namespace Microsoft.Insights
az provider register --namespace Microsoft.Keyvault
az provider register --namespace Microsoft.Kubernetes
az provider register --namespace Microsoft.KubernetesConfiguration
az provider register --namespace Microsoft.ManagedIdentity
az provider register --namespace Microsoft.ManagedNetworkFabric
az provider register --namespace Microsoft.Network
az provider register --namespace Microsoft.NetworkCloud
az provider register --namespace Microsoft.OperationalInsights
az provider register --namespace Microsoft.OperationsManagement
az provider register --namespace Microsoft.ResourceConnector
az provider register --namespace Microsoft.Resources
az provider register --namespace Microsoft.Storage
az provider register --namespace Microsoft.NexusIdentity

EncryptionAtHost feature registration

You must enable EncryptionAtHost feature for your subscription. Use the following steps to enable the feature for your subscription:

Register the EncryptionAtHost feature:

Execute the following command to register the feature for your subscription

Azure 
az feature register --namespace Microsoft.Compute --name EncryptionAtHost

Verify the registration State:

Confirm that the registration state is Registered (registration might take a few minutes) using the following command before trying out the feature.

Azure 
az feature show --namespace Microsoft.Compute --name EncryptionAtHost

Register the Resource Provider:

Azure 
az provider register --namespace Microsoft.Compute

Ensure that the registration state is Registered.

Dependent Azure resources setup

  • Establish ExpressRoute connectivity from your on-premises network to an Azure Region:
    • ExpressRoute circuit creation and verification can be performed via the Azure portal
    • In the ExpressRoute blade, ensure Circuit status indicates the status of the circuit on the Microsoft side. Provider status indicates if the circuit is provisioned or not provisioned on the service-provider side. For an ExpressRoute circuit to be operational, Circuit status must be Enabled, and Provider status must be Provisioned
  • Set up Azure Key Vault to store encryption and security tokens, service principals, passwords, certificates, and API keys
  • Set up Log Analytics WorkSpace (LAW) to store logs and analytics data for Operator Nexus subcomponents (Network Fabric, Cluster, etc.)
  • Set up Azure Storage account to store Operator Nexus data objects:
    • Azure Storage supports blobs and files accessible from anywhere in the world over HTTP or HTTPS
    • this storage isn't for user/consumer data.
