Abstract

Network virtualization has emerged as a transformative technology for optimizing cloud infrastructure management. By abstracting physical network resources into multiple logical networks, it enables efficient utilization, isolation, and scalability. This paper explores the principles and architecture of network virtualization, its integration with Software-Defined Networking (SDN), and its role in enhancing agility, automation, and performance in cloud environments. Furthermore, it investigates challenges related to security, orchestration, and interoperability while identifying future research directions. The findings suggest that network virtualization is key to achieving flexible, scalable, and cost-effective cloud infrastructures capable of meeting the demands of next-generation digital services.
