Azure CLI script example: Load balance multiple websites

This Azure CLI script sample creates a virtual network with two virtual machines (VM) that are members of an availability set. A load balancer directs traffic for two separate IP addresses to the two VMs. After running the script, you could deploy web server software to the VMs and host multiple web sites, each with its own IP address.

Sample script

Clean up deployment

Run the following command to remove the resource group, VM, and all related resources.

az group delete --name myResourceGroup --yes

Script explanation

This script uses the following commands to create a resource group, virtual network, load balancer, and all related resources. Each command in the table links to command specific documentation.

Command	Notes
az group create	Creates a resource group in which all resources are stored.
az network vnet create	Creates an Azure virtual network and subnet.
az network public-ip create	Creates a public IP address with a static IP address and an associated DNS name.
az network lb create	Creates an Azure Load Balancer.
az network lb probe create	Creates a load balancer probe. A load balancer probe is used to monitor each VM in the load balancer set. If any VM becomes inaccessible, traffic is not routed to the VM.
az network lb rule create	Creates a load balancer rule. In this sample, a rule is created for port 80. As HTTP traffic arrives at the load balancer, it is routed to port 80 one of the VMs in the load balancer set.
az network lb frontend-ip create	Create a frontend IP address for the Load Balancer.
az network lb address-pool create	Creates a backend address pool.
az network nic create	Creates a virtual network card and attaches it to the virtual network, and subnet.
az vm availability-set create	Creates an availability set. Availability sets ensure application uptime by spreading the virtual machines across physical resources such that if failure occurs, the entire set is not effected.
az network nic ip-config create	Creates an IP confiuration. You must have the Microsoft.Network/AllowMultipleIpConfigurationsPerNic feature enabled for your subscription. Only one configuration may be designated as the primary IP configuration per NIC, using the --make-primary flag.
az vm create	Creates the virtual machine and connects it to the network card, virtual network, subnet, and NSG. This command also specifies the virtual machine image to be used and administrative credentials.
az group delete	Deletes a resource group including all nested resources.
