What is network virtualization?

Network virtualization is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity called a virtual network. This technology allows multiple virtual networks to run on top of a single physical network infrastructure, enabling more flexible, scalable, and efficient network management. Network virtualization is commonly used in data centers to improve resource utilization, simplify network management, and support cloud computing environments. It also enhances network agility, security, and reduces operational costs by streamlining network provisioning and configuration.
