What is the function of Azure Virtual Network?

The function of Azure Virtual Network is to provide a secure and isolated network for Azure resources. This capability allows users to create private networks within the Azure cloud that can segment resources and control communication both internally among Azure services and externally to the internet. By offering features like subnets, network security groups, and routing, Azure Virtual Network enhances security by isolating resources from public access, thus enabling companies to manage their security requirements effectively.

In addition, Azure Virtual Network supports various configurations for connecting to on-premises networks through VPN gateways or Azure ExpressRoute, allowing for greater flexibility and security in hybrid cloud environments. This strict isolation and control over the network make it an essential feature for organizations looking to protect sensitive data and create a fully operational virtualized network infrastructure within Azure.
