Azure Virtual Network Manager (In Preview), is a central management service for your virtual network resources, significantly reducing your operational overhead. Easily manage your virtual network infrastructure while scaling your cloud-based workloads. Use the centralized solution to create and manage complex network topologies and network security rules globally across subscriptions.

The brief tutorial explains how to deploy three networks and how Azure Virtual Network Manager can create a single mesh topology. Then we’ll look at the networking configuration got applied correctly (hub and spoke config)

More details here: What is Azure Virtual Network Manager (Preview)? | Microsoft Docs

Let’s get started.

  1. Go to resources and select Network Manager to create a new:

2. I already have 3 vNET and a Hub vNET created – I will use network manager to deploy the Hub and Spoke topology.

3. Next step is to create a group, and all spoke vNETs to it:

4. After creating a group, the next step is to add the configuration.

5. I will choose Hub and Spoke here and also select Hub vNET. Additionally, choose the vNET group that I created above.

6. Wait for a successful message.

7. The config would look like this:

8. The next step is to deploy the configuration – ie. create a hub and spoke topology.

So click on Deploy and push the configuration as shown:

9. Deploy the configuration, which should ideally take 1-2 minutes and Hub-Spoke topology will be created for the select vNETs

10. Checking at the Hub vNET – peering is created with all the vNET’s

What are common use cases for using Azure Virtual Network Manager?

  • As an IT security manager, you can create different network groups to meet the requirements of your environment and its functions. For example, you can create network groups for Production and Test network environments, Dev teams, Finance departments, etc. to manage their connectivity and security rules at scale.
  • You can apply connectivity configurations to create a mesh or a hub-and-spoke network topology for a large number of virtual networks across your organization’s subscriptions.
  • You can deny high-risk traffic: As an administrator of an enterprise, you can block specific protocols or sources that will override any NSG rules that would normally allow the traffic.  
  • Always allow traffic: You want to permit a specific security scanner always to have inbound connectivity to all your resources, even if there are NSG rules configured to deny the traffic.

Q: How can I manage network resources across subscriptions using Azure Virtual Network Manager?

A: Azure Virtual Network Manager enables you to manage network resources, such as virtual networks, subnets, and network security groups, across multiple subscriptions. You can use the unified management interface to view and manage all your network resources in one place.

Q: What is an Azure Virtual Network?

A: An Azure Virtual Network is a representation of your own network in the cloud. It is a logical isolation of the Azure cloud dedicated to your subscription. It allows you to securely connect Azure resources, such as virtual machines, to each other and to on-premises networks.

Q: How can I learn more about Azure Virtual Network?

A: You can learn more about Azure Virtual Network by visiting the official Azure blog or by referring to the documentation on the Azure website. Additionally, you can explore online resources and tutorials for in-depth learning.

Q: What is network peering in Azure?

Q: How do I create a virtual network peering?

A: To create a virtual network peering, you need to have the required permissions as a network administrator or a user with the necessary network group membership. Then, you can use the Azure portal or the Azure CLI to configure the peering between the virtual networks.

Q: What are security admin rules in Azure Virtual Network?

A: Security admin rules in Azure Virtual Network are a set of rules that define the network connectivity and security between resources. They are used to manage and control the traffic flow within the virtual network, ensuring secure communication between resources.

Q: How can I use security admin rules?

Q: What is the purpose of a single virtual network in Azure?

A: A single virtual network in Azure allows organizations to define a private, isolated, and highly-secure environment to run their services. Since a virtual network provides dedicated, non-overlapping IP address space, resources can communicate with each other securely and efficiently.

Q: How can you effectively handle traffic from multiple network sources?

A: Administrators can use security admin rules to manage and control traffic. These rules aim to handle traffic differently as needed, allowing teams to flexibly pinpoint security as needed through NSG (Network Security Group) rules. Security admin rules can be set to allow certain traffic, block specific traffic, or protect network resources.

Q: How does one set up a security admin configuration in Azure?

A: To set up a security admin configuration, one would first define a network group using the Azure VNET (Virtual Network) management tools. Once the network group is defined, you can create a security admin rule specific to that group. These security admin rules are evaluated based on their priority, and they dictate the connectivity and security admin policies for the VNets in the network group. The benefits of security admin rules include the ability to protect VNets at scale with security admin configurations and to flexibly adjust security as needed through NSG rules.
