Lab scenario

Your organization is migrating hub and spoke network topologies to Azure. As the Azure Administrator you need to:

  • Replicate the on-premises functionality in Azure.
  • Configure virtual network peering and traffic routing.
  • Implement load balancer and application gateway functionality.
  • Test to ensure traffic management is flowing as intended.

Objectives

  • Task 1: Provision the lab environment. In this task, you deploy four virtual machines into the same Azure region. The first two reside in a hub virtual network, while the remaining two reside in a separate spoke virtual network.
    • Review an Azure Resource Manager template.
    • This template includes the virtual machines and virtual networks in the underlying architecture.
    • Use Azure PowerShell to install the Network Watcher extension on the Azure virtual machines.
  • Task 2: Configure the hub and spoke network topology. In this task, you configure local peering between the virtual networks you deployed in the previous tasks in order to create a hub and spoke network topology.
    • Configure virtual network peering between the virtual networks.
    • Ensure forwarded traffic is allowed to facilitate routing between spoke virtual networks.
  • Task 3: Test transitivity of virtual network peering. In this task, you test transitivity of virtual network peering by using Network Watcher.
    • Use Network Watcher to verify peered networks are reachable.
    • Use Network Watcher to verify unpeered networks are unreachable.
  • Task 4: Configure routing in the hub and spoke topology. In this task, you configure and test routing between the two spoke virtual networks.
    • Enable IP forwarding on a virtual machine.
    • Install the remote access Windows feature with associated tools.
    • Create routing tables and associate them with the appropriate subnets.
    • Use Network Watcher to verify traffic routed through the virtual machine.
  • Task 5: Implement Azure Load Balancer. In this task, you implement an Azure load balancer in front of the two Azure virtual machines in the hub virtual network.
    • Create a load balancer with a public IP address.
    • Create a back-end pool that includes the virtual machines.
    • Add a load balancing rule to alternate between virtual machines in the back-end pool.
    • Test to confirm that the load balancer is working correctly.
  • Task 6: Implement Azure Application Gateway. In this task, you implement an Azure application gateway in front of the two Azure virtual machines in the spoke virtual networks.
    • Create a dedicated subnet for the application gateway.
    • Create an application gateway with a public IP address.
    • Configure the application gateway back-end pool to include the virtual machines.
    • Test to ensure traffic is balanced across the back-end virtual machines.
