What is vNet or Virtual Network?

virtual network 

Virtual network or simply vNet represents a customer's network on Azure, providing an isolated network address field. It is essential to produce resources in the likes of VM, PaaS, and IaaS on Azure.

That being said, vNet or is very similar to VLAN that we already know for an on-prem network employing conventional switches.

In order to optimally configure transitivity and connections, vNet uses Azure Virtual Network Manager as a peer for the hub connectivity. However, the connection is established as vNet-to-vNet connectivity. AVNM was presented at the Ignite conference by Microsoft.

Additionally, at Ignite, Microsoft announced a preview of the Ebs v5 series of virtual machines with higher memory and supported up to 120.000 I/O operations per second (IOPs). The bandwidth to remote storage is up to 4.000 MBPS which is super impressive. Ignite is constantly surprising in terms of announcements, and the virtual nature of this year's event makes it feel even further.

With the guidance of Azure Virtual Network Manager, you can effortlessly manage virtual networks in Azure from a single pane of glass. It is innovative connectivity which, like peering, requires no extra hops in the traffic.

Let's suppose you have existing vNets that you import into AVNM, and they already have configured spin. In that case, you can optionally discard/delete existing AVNM connections to bring them into centralized management.

How do you create a vNet?

There are several ways to create vNet - the two most common methods are to use the Azure management portal or to use a virtual network configuration file, which is an XML file. You can also use the PowerShell commands or the Azure command-line interface (CLI).

By default, all resources within the same vNet can communicate with each other without any restrictions.

You can determine the address range as public or private, and it can only be reached within the virtual network or any interconnected networks on the premises.

vNet subnets

vNet subnets are created under vNet spaces and usually represent an IP subnet range for different zones or layers of the network.

Without deploying any virtual machines or services, you will be able to add, expand, remove, or shrink a subnet. It is performed with the usage of the NETCFG file or the PowerShell cmdlets.

Features of Azure vNet

  • Develop a hybrid infrastructure that you control.
  • Construct your IP addresses and DNS servers
  • Ensure your connections with IPSec VPN or ExpressRoute
  • Get granular traffic control between subnets
  • Create sophisticated network topologies using virtual machines.
  • Get an isolated, secure environment for your applications
  • RLI is connected

Fundamental features of Azure Virtual Network Manager

  • Global management of virtual network resources across regions and subscriptions
  • Automatically manage and extend virtual network topologies such as hub and speech and network
  • Drive high-level security rules to protect your network resources
  • Straightforward deployment of network configurations

Benefits of Azure vNet

  • Establish networks of your choice in Azure.
  • Use complex or simple topologies to meet safety compliance standards.
  • Connect by selecting external WAN connections.
  • Set networks as you would in your data center

Conclusion

Azure Virtual Networks lets you organize your virtual lab in the cloud. You can create several virtual machines in Azure and then connect these virtual machines using the Azure Virtual Network Manager.

Furthermore, Azure Virtual Networks lets you set up a virtual lab in the cloud and connect to on-site resources using VPN connections from site to location and point to the spot.
