The primary goal of network virtualization is to separate network functions and resources from the underlying hardware. This approach enables the creation of multiple virtual networks over a single physical infrastructure, allowing for flexible management and allocation of network resources. By abstracting network functions, organizations can enhance scalability, improve resource utilization, and simplify network management. Network virtualization also supports the deployment of virtual machines and containerized applications, promoting efficient use of resources and facilitating rapid provisioning and adaptation to changing demands within an organization's network.
