Deploy Cluster Nodes Manually - NLB-based Deployment

Deploy the cluster nodes so they form a cluster.

Procedure

1

Create a Virtual Machine Scale Set from the Marketplace image with 0 instance count using the az vmss create CLI.

az vmss create --resource-group <ResourceGroupName> --name <VMSSName> --vm-sku <InstanceSize> --image <FTDvImage> --instance-count 0 --admin-username <AdminUserName> --admin-password <AdminPassword> --plan-name <ftdv-azure-byol/ftdv-azure-payg> --plan-publisher cisco --plan-product cisco-ftdv --plan-promotion-code <ftdv-azure-byol/ftdv-azure-payg> --vnet-name <VirtualNetworkName> --subnet <MgmtSubnetName>

2

Attach 4 interfaces—Diagnostic, Inside, Outside, and Cluster Control Link.
3

Go to the virtual machine scale set you have created and perform the following:

  1. Under the Operating system section, add the day0 configuration in the customData field.

  2. Click Save.

  3. Under the Scaling section, update the instance count with the required cluster node. You can set the instance count range of minimum 1 and maximum 16.

Add the control node to the Management Center. See Add the Cluster to the Management Center (Manual Deployment).
