Azure Virtual Network
Azure Virtual Network (VNet) is a networking service in Microsoft Azure that enables you to create isolated, private networks in the cloud. It allows you to securely connect Azure resources like virtual machines, app services, and databases, and optionally extend your on-premises network to Azure using VPN or ExpressRoute. VNets provide features such as subnetting, custom DNS, network security groups, and routing control.
Developers should learn Azure Virtual Network when building cloud-native applications on Azure that require secure, isolated networking, such as multi-tier architectures, hybrid cloud setups, or compliance-driven environments. It's essential for scenarios like connecting VMs in different subnets, implementing network segmentation for security, or integrating with on-premises infrastructure for hybrid operations.
