Azure Virtual Network

Azure Virtual Networks (VNets) is the core unit Azure networking component, from which administrators can have full control over IP address assignments, name resolution, security settings, and routing rules.

Azure Virtual Networks (VNet) provide the infrastructure for deploying workloads that require an advanced network configuration. VNets provide support for hybrid network connectivity from Azure to either your on-premises network or to other VNets within Azure regions. The use of VMs in Azure is entirely dependent upon the VNets where deployed. These can be internet-facing applications that are deployed behind either the Azure load balancer for Layer 4 workloads, or the Azure Application Gateway, which can deploy more complex Layer 7 implementations. Azure VNets also provide support for deploying intranet or n-tier workloads using the internal load balancer. Workloads, such as Active Directory, are also enabled in the cloud using features only supported in VNets (such as subnets and static IP addresses).
