A VNet is a virtual network in Azure, very similar to a VPC in AWS. It can contain subnets (both private and public) and is usually the top-level network component in Azure architectures within a Region, separating network artifacts belonging to one organization from others.

An Azure Virtual Network (VNet) is a network or environment that can be used to run VMs and applications in the cloud. Concrete Tampa

An Azure Virtual Network (VNet) is a representation of your own network in the cloud. It is a logical isolation of the Azure cloud dedicated to your subscription. You can use VNets to provision and manage virtual private networks (VPNs) in Azure and, optionally, link the VNets with other VNets in Azure, or with your on-premises IT infrastructure to create hybrid or cross-premises solutions. Each VNet you create has its own CIDR block and can be linked to other VNets and on-premises networks as long as the CIDR blocks do not overlap. You also have control of DNS server settings for VNets, and segmentation of the VNet into subnets.

Virtual Network is a private network in your network to secure connectivity and traffic of your workload and restrict it only within your organization’s private environment. Azure provides multiple connectivity methods to connect from VNET to public cloud Azure services
