Ever wondered what Azure Virtual Network Manager is all about? This network management service is designed to enable you to group, manage, deploy, and configure virtual networks globally across subscriptions. The system allows users to define network groups for logically segmenting their virtual networks for optimized management. Once network groups are defined, users can then determine the connectivity and security configurations they desire and apply these configurations across the selected virtual networks in the network groups.
Azure Virtual Network Manager is currently in General Availability for Virtual Network Manager and hub and spoke connectivity configurations while the mesh connectivity configurations and security admin rules remain in Public preview. It's crucial to be aware that the preview version is provided without a service level agreement and isn't recommended for production workloads as certain features might not be supported or may have constrained capabilities.
One may wonder, "how does the Network Manager function?" During the creation process, the scope for what your Virtual Network Manager manages is defined. This scope limits the delegated access to apply configurations within this scope boundary. While defining a scope can be done directly on a list of subscriptions, it is advisable to use management groups to define your scope as these groups offer a hierarchical organization to your subscriptions. After defining the scope, you will deploy configuration types including Connectivity and SecurityAdmin rules for your Virtual Network Manager.
Once the Network Manager has been deployed and a network group has been created, the next step involves selecting individual virtual networks to be added to your network group, a process known as static membership. Alternatively, Azure Policy can be utilized to define the conditions governing group membership dynamically or dynamic membership. Further details on Azure Policy initiatives can be found at Azure Virtual Network Manager and Azure Policy.
The creation of connectivity and/or security configuration(s) to be applied to the network groups based on your topology and security needs comes up next. These configurations allow you to create a mesh or a hub-and-spoke network topology and define a collection of rules that can be applied globally to one or more network groups. Once your desired network groups and configurations have been created, you can deploy the configurations to any region of your choice.
The Azure Virtual Network Manager comes with a host of benefits. These include: the ability to centrally manage connectivity and security policies globally across regions and subscriptions; enabling direct connectivity between spokes in a hub-and-spoke configuration without the complexity of managing a mesh network; high scalability and availability; redundancy and replication across the globe; creating network security rules that override network security group rules; low latency and high bandwidth between resources in different virtual networks using virtual network peering; and, lastly, the ability to rollout network changes through a specific region sequence and frequency of choice.

The Azure Virtual Network Manager is a feature of the vast Microsoft Azure platform, known for its capability to enable the creation, deployment, and management of virtual networks across subscriptions on a global scale. azure. It lets users define network groups, a concept that assists in segmenting and identifying distinct virtual networks, allowing them to apply their chosen connectivity and security settings to all the relevant virtual networks at one go.
Note:
As of now, the Azure Virtual Network Manager is in General Availability for its hub and spoke connectivity options. However, the mesh connectivity options and security admin rules are still made available only in Public Preview, which doesn't offer any service level agreement and is not suitable for production workloads. Many features may still be under development or may have limited capabilities. This availability status is as per Microsoft Azure's Supplemental Terms of Use.
Let's delve into the way the Azure Virtual Network Manager functions. When you initiate the creation process, you begin by setting the scope boundary within which your Virtual Network Manager can apply configurations. The scope can be defined directly on a subscription list, but it's suggested to employ management groups for this purpose as they offer a hierarchical organization to your subscriptions. Afterwards, you may proceed to deploy configuration types inclusive of Connectivity and SecurityAdmin rules.
After configuring the network groups to your satisfaction, you get the option to deploy to any regional location of your choice.
This management tool comes with a handsome bunch of merits:
