Virtual networks (VNets, in Azure), maintain the same characteristics as physical networks. The processes of physical networks enable data from one computer to be transported over Transmission Control Protocol, Internet Protocol (TCP/IP) to another computer. The information, or data, is transformed so that TCP/IP packets can transport it efficiently; it is sent to another computer through hardware network interface cards (NICs) via physical network switches. To send the data to and from other buildings and other datacenters, network engineers use hardware devices referred to as gateways. Additionally, in datacenters today, the hardware provides network architects with the ability to virtualize physical networks or subnetworks () into a virtual network subnet called a . How would your budget be improved if Azure VNets reduced the need for a considerable amount of physical networking equipment?
