Network virtualization (NV) is the act of combining a network's physical hardware into a single virtual network. This is often accomplished by running several virtual guest computers in software containers on a single physical host system.
Network virtualization is the gold standard for networking, and it is being adopted by enterprises of all kinds globally. By integrating their existing network gear into a single virtual network, enterprises can save operating expenses, automate network and security processes, and set the stage for future growth.
Businesses can use virtualization to imitate many types of traditional hardware, including servers, storage devices, and network resources.
Three Forces Driving Network Virtualization
Demand for enterprise networks keeps rising, driven by higher end-user demands and the proliferation of devices and business software. Through network virtualization, IT businesses are gaining the ability to respond to evolving needs and match their networking capabilities with their virtualized storage and computing resources.
According to a recent SDxCentral survey, 88% of respondents believe that adopting a network virtualization solution is "mission critical" and that it is necessary to assist IT in addressing the immediate requirements of flexibility, scalability, and cost savings (both OpEx and CapEx) in the
data center.
Today, consider any business as an example. Everything depends on IT's capacity to assist business operations. When a company wants to 'surprise' its clients with a new app, launch a competitive offer, or pursue a fresh route to market, it requires immediate IT assistance. That implies IT must move considerably more swiftly, and networks must evolve at the rapid speed of a digitally enabled organization.
According to a PricewaterhouseCoopers survey, the average organization experiences two successful cyberattacks every week. Perimeter security is just insufficient to stem the flood, and network experts are called upon to provide a better solution.
The new data center security approach will:
-
Be software-based
-
Use the micro-segmentation principle
-
Adopt a Zero Trust (ZT) paradigm
In an ideal world, there would be no difference between trustworthy and untrusted networks or sectors, but a ZT model necessitates a network
virtualization technology that allows micro-segmentation.
Thanks to the emergence of server virtualization, applications are no longer linked to a specific physical server in a single location. Applications can now be replicated to eliminate a data center for disaster recovery, moved through one corporate data center to another, or slipped into a
hybrid cloud environment.
The problem is that network setup is hardware-dependent, and hardwired networking connections restrict them. Because networking services vary significantly from one data center to the next, as an in-house data center differs from a cloud, you must perform extensive personalization to make your applications work in different network environments—a significant barrier to app mobility and another compelling reason to utilize network virtualization.
Closing Lines
Network virtualization is indeed the future technology. These network virtualization platform characteristics benefit more companies as CIOs get more involved in organizational processes. As consumer demand for real-time solutions develops, businesses will be forced to explore network virtualization as the best way to take their networks to another level.
