Network virtualization software allows companies to virtually discover and view network conditions, reconstruct network conditions, and improve network performance.

Physical networks that are manually set up by companies can be managed and configured through network virtualization software. The technology is being embraced by companies, with 92% of them using network virtualization as of 2020.

Network Virtualization Market

According to market data forecasts, the network virtualization market is worth $18 billion in 2021 and is expected to grow to $51 billion by 2027, representing a compound annual growth rate (CAGR) of 23%.

Several industries are driving the growth of the network virtualization market: banking, financial services and insurance (BFSI), manufacturing, retail, healthcare, education, and transportation.

Relatedly, 45% of enterprises are planning or considering migrating their servers to a network virtualization architecture, and 25% are considering migrating their storage to network virtualization, according to SpiceWorks.

There are a variety of other operational and cost drivers in the network virtualization space:

• CAPEX and OPEX savings for businesses
• Growing Demand for Mobility
• Growing demand for data center and server virtualization
• Invest in 5G technology
• Lower telecom operator costs

Network Virtualization Features

There are two key types of network virtualization:

• External Network Virtualization: Pull multiple local networks into a single network for greater efficiency.
• Internal Network Virtualization: A network that simulates a physical network.

feature:

• toggle
• routing
• load balancing
• distribution firewall
• scene-aware micro-segmentation
• Automation and cloud management

Benefits of Network Virtualization

• Energy costs: According to VMware, energy is saved by an average of 80% due to limited servers. "Virtualization enables the reuse and retirement of some existing servers. According to UptimeInstitute, decommissioning a single 1U rack server can save $500 per year in energy, $500 in operating system licensing, and $1,500 in hardware maintenance costs," EnergyStar said.
• Lower hardware costs: Reduce the number of servers in the network.
• Disaster Recovery: Virtualized hardware resources and data support disaster recovery (DR) planning, testing, and execution
• Lower hardware costs: Reduce the number of servers in the network.
• Agility and Speed: Team members can access IT resources faster to improve the network
• Improve security: Capture and eliminate cyber threats such as malware, making the network and associated applications more secure and less likely to cause problems.

Network Virtualization Use Cases

Hepta Technologiae Informática has 300 virtual machines, they want better security, they feel like they are using VMware NSX.

"VMware NSX is a network virtualization platform that follows the same model already used for server virtualization," said Jorge Filho, virtualization analyst at Hepta Technologiae Informática.

The software has "tools that help with troubleshooting, such as traffic monitoring, packet capture, and trace flows in a graphical interface," Filho said.

Cisco's Application Centric Infrastructure (ACI) for Software Defined Networking (SDN) is implemented in the data center to "manage internal user traffic on the applications used to separate external users from tenants", a telecom Engineers say TrustRadius for the industry.

"The platform is very scalable, which makes network migration easier for implementers," they said.

According to a FierceTelecom article, Verizon CEO Lowell McAdam believes that virtualization will save the company nearly $10 billion by 2021.

Verizon executive vice president and president of global operations John Stratton also called network virtualization a "very powerful" opportunity, FierceTelecom reported.

"We have a very, very strong technology team that's been working on finding ways to leverage the investments we've made there, with network virtualization as the direction," Stratton said.

Stratton said Verizon's customers "still want a very intuitive, simple, effortless online experience," and he believes network virtualization can help deliver that experience.
