| 12 | +# Operator Nexus Azure resources prerequisites |
| 13 | + |
| 14 | +To get started with Operator Nexus, you need to create a Network Fabric Controller (NFC) and then a Cluster Manager (CM) |
| 15 | +in your target Azure region. |
| 16 | + |
| 17 | +Each NFC is associated with a CM in the same Azure region and your subscription. |
| 18 | +The NFC/CM pair lifecycle manages up to 32 Azure Operator Nexus instances deployed in your sites connected to this Azure region. |
| 19 | + |
| 20 | +You'll need to complete the prerequisites before you can deploy the Operator Nexus first NFC and CM pair. |
| 21 | +In subsequent deployments of Operator Nexus, you can skip to creating the NFC and CM. |
| 22 | + |
| 23 | +## Resource Provider Registration |
| 24 | + |
| 25 | +- Ensure Azure Subscription for Operator Nexus resources has been permitted access to the |
| 26 | + necessary Azure Resource Providers: |
| 27 | + - Microsoft.NetworkCloud |
| 28 | + - Microsoft.ManagedNetworkFabric |
| 29 | + - Microsoft.HybridContainerService |
| 30 | + - Microsoft.HybridNetwork |
| 31 | + - Microsoft.Storage |
| 32 | + - Microsoft.Keyvault |
| 33 | + - Microsoft.Network |
| 34 | + - Microsoft.ExtendedLocation |
| 35 | + - Microsoft.HybridCompute |
| 36 | + - Microsoft.HybridConnectivity |
| 37 | + - Microsoft.HybridContainerService |
| 38 | + - Microsoft.Insights |
| 39 | + - Microsoft.Kubernetes |
| 40 | + - Microsoft.KubernetesConfiguration |
| 41 | + - Microsoft.OperationalInsights |
| 42 | + - Microsoft.OperationsManagement |
| 43 | + - Microsoft.ResourceConnector |
| 44 | + - Microsoft.Resources |
| 45 | + |
| 46 | +## Dependant Azure resources setup |
| 47 | +- Establish [ExpressRoute](/azure/azure/expressroute/expressroute-introduction) connectivity |
| 48 | + from your on-premises network to an Azure Region: |
| 49 | + - ExpressRoute circuit [creation and verification](/azure/azure/expressroute/expressroute-howto-circuit-portal-resource-manager) |
| 50 | + can be performed via the Azure portal |
| 51 | + - In the ExpressRoute blade, ensure Circuit status indicates the status |
| 52 | + of the circuit on the Microsoft side. Provider status indicates if |
| 53 | + the circuit has been provisioned or not provisioned on the |
| 54 | + service-provider side. For an ExpressRoute circuit to be operational, |
| 55 | + Circuit status must be Enabled, and Provider status must be |
| 56 | + Provisioned |
| 57 | +- Set up Azure Key Vault to store encryption and security tokens, service principals, |
| 58 | + passwords, certificates, and API keys |
| 59 | +- Set up Log Analytics WorkSpace (LAW) to store logs and analytics data for |
| 60 | + Operator Nexus subcomponents (Network Fabric, Cluster, etc.) |
| 61 | +- Set up Azure Storage account to store Operator Nexus data objects: |
| 62 | + - Azure Storage supports blobs and files accessible from anywhere in the world over HTTP or HTTPS |
| 63 | + - this storage isn't for user/consumer data. |
| 64 | + |
| 65 | +## Install CLI Extensions and sign-in to your Azure subscription |
| 66 | + |
| 67 | +Install latest version of the |
| 68 | +[necessary CLI extensions](./howto-install-cli-extensions.md). |
| 69 | + |
| 70 | +### Azure subscription sign-in |
| 71 | + |
| 72 | +```azurecli |
| 73 | + az login |
| 74 | + az account set --subscription $SUBSCRIPTION_ID |
| 75 | + az account show |
| 76 | +``` |
| 77 | + |
| 78 | +>[!NOTE] |
| 79 | +>The account must have permissions to read/write/publish in the subscription |
| 80 | +
|
| 81 | +## Create steps |
| 82 | + |
| 83 | +- Step 1: [Create Network Fabric Controller](./howto-configure-network-fabric-controller.md) |
| 84 | +- Step 2: [Create Cluster Manager](./howto-cluster-manager.md) |
| 85 | +- |
