What is the Azure Virtual Network?

Networking is an essential concept for computing workloads and data centers in the cloud. Your resources must communicate with one another and be resilient against cyber threats or other outside events. Virtual networking allows for communication between multiple computers, virtual servers, machines, or devices from different offices and data centers. Virtual networks use traditional tools like switches and network adapters to make routing and configuration seamless.
Virtual networking allows network administrators to modify the network without having to buy new hardware. It also gives them flexibility in network provisioning and the ability to move data between networks without worrying about security. It is the foundation for cloud architectures and applications because it allows users to access, modify, modify, and secure cloud resources.
Why use an Azure Virtual Network instead of a physical network?
The main reason to choose the Azure virtual network is because it allows Azure resources to communicate.
A VNet can also be used to accomplish key scenarios, such as:
Communication of Azure resources to the internet
Filtering network traffic
Communication between Azure resources
Integration with Azure services
Communication with on-premises resources
Routing network traffic
You can also modify the communication settings to only allow inbound communication via the internet, apart from these network options. This allows you to set up rules to add a Load Balancingr or a public Internet Protocol.
Virtual Network Limits and Availability
Azure Virtual Network has limits on Azure resources that can be deployed to the cloud. The default networking limits for most Azure Virtual Networks are set at maximum. However, you can increase them if necessary. You can refer to the VNet limits pages for more information about increasing networking limits.
All availability zones within a region are included in the Azure Virtual Networks and subnets that span them. You don’t need to divide zonal resources by availability zones if you have the need to.
Azure provides many tools and services to manage the cloud infrastructure. Azure Resource Manager is one key service that Azure Administrators use to effectively manage cloud resources. Learn more about Azure Resource Manager in our blog.
Elements of Azure Virtual Networks
Azure VNets offer many functionalities and services when you connect to Azure resources. These services are combined to ensure that organizations have all the tools they need for smooth cloud deployment.
Address Space
This is the first step in creating a VNet. It involves assigning an IP address space private in the range RFC 1918. This IP address space will also contain other familiar IP addresses such as and You may also notice that there are multiple IP address ranges within a virtual network, which can be used to create additional subnets.
Subnets are the smaller segments of the virtual network. These Subnets are used to target specific resources and VNet portions.
Network Security Groups
Network Security Groups (NSGs) are used to protect subnets of the Virtual Network and filter out traffic from that network. To filter the traffic, you must first define the source and destination. Next, you will need to choose the port and protocol to identify the traffic.
Routing and peering
Azure is designed to automatically determine the best routes between subnets and on-premises networks as well as virtual networks. You can however create route tables to help control traffic for each subnet.
You must be a Microsoft Azure Administrator to create an Azure Virtual Network.
Microsoft Azure Administrators are certified by Microsoft and can create virtual networks or support cloud team members with their activities. Learn more about their roles and the training they need by visiting our Azure Administrator guide blog.
