A virtual network is a virtual link between two computers. A virtual network can be used to connect two or more computers, or it can be used to connect two or more networks that are on different subnets. The latter is often called a "virtual LAN."

Benefits of Virtual Networks

Virtual networks can be helpful for a variety of reasons. For example, they allow you to:

  • reduce costs by reducing the number of physical switches required and optimizing network topologies
  • improve security by segmenting traffic according to need; this is especially critical in the case of virtualization, which makes it easier than ever to hack into your server infrastructure unless you take precautions
  • increase flexibility by providing more options for management and configuration; you can choose how much control over the network you want to delegate to users or third parties

How do you get started?

Look at the virtual networks out there and decide which one best fit for your needs. Once you've found one that seems promising, it's time to go deeper:

  • find a community within that network
  • join in on some of their projects

It helps if they're working on something that interests you.

Now that you know the basics of virtual networks, it's time to start creating one. To create a virtual network in Azure e.g.:

  • go to the Azure portal and click New on the left menu. Select Networking, which will launch the Virtual Network blade
  • create a gateway in your virtual network by clicking Add on the right side of this blade

This will initiate a wizard where you can select public or private cloud regions and specify connection methods like Direct Connect and ExpressRoute (available only in specific markets). Once done with this step:

  • create a subnet within your gateway by clicking Add Azure Subnet
  • in either case—public or private—and give it an IP address range (this can be different from what you set for your VNets)

You'll also need to decide whether this will be part of Microsoft's Edge services by checking Allow Traffic From Your On-Premises Networks if applicable; otherwise, traffic will be restricted until the further configuration.

Connecting between VNets has traditionally been challenging due to its complexity but luckily there are now many ways for doing so depending on your preferences including NAT Gateway or VPN connections.


If you're curious about virtual networks, I hope this article was helpful! Virtual networks are a great way to connect with people and make new friends. They allow you to share stories and experiences with people worldwide without leaving your home. If you want to go deeper into virtual Networking, let's talk!!!
