What are the roles of network virtualization in resource optimization?

Network virtualization optimizes the allocation of resources across different applications and services by decoupling network resources from physical infrastructure. This allows for more efficient resource utilization, as virtual networks can be dynamically adjusted and scaled based on the needs of specific applications or services. Additionally, network virtualization enables isolation and segmentation of network environments, enhancing security and performance for individual applications. Overall, this approach increases flexibility, scalability, and efficiency in managing network resources.
