Azure Virtual Network

A Virtual Network (VNet) is a fundamental building block for your private network in Azure. It provides an isolated and secure environment for running your Azure resources such as VMs, Azure App Service Environments, and databases. VNets enable many types of Azure resources to securely communicate with each other, the internet, and on-premises networks. Isolation and Segmentation : VNets provide isolation from other VNets and on-premises networks. Communication : VNets allow Azure resources to communicate with each other and with the internet. Customization : You can define subnets, assign custom private IP address ranges, configure route tables, and network security groups (NSGs) for VNets. Integration : VNets can integrate with on-premises IT environments through VPNs or ExpressRoute. Azure Virtual Network Azure Virtual Network (VNet) is a foundational network service that allows you to securely connect Azure resources to each other, to the internet, and to on-premises networks.
