Network Virtualization – Everything you need to know about this technology

We live in an era of digital revolution where data is the most important commodity. As our data generation increases, the demand for elements like data security, storage, processing power and energy also increases. In order to cater all these demands virtualization is employed. Virtualization is a technology that is being adopted by many companies due to its efficient, secure, flexible and cost-efficient nature.

What is Virtualization?

Virtualization is the innovative technology through which virtual resources of physical assets are created. These assets can range from servers and operating systems to desktops and networks. Reasons for adopting virtualization vary across organizations. Some want to make their traditional data centers more flexible in nature i.e. scalable architecture-wise, several companies require optimization in performance, several opt for it to enhance their data security and management while a few want an environment-friendly infrastructure by reduction of their carbon footprint. There are seven main types of virtualization i.e. server, network, application, administrative, hardware and storage. In this article, we will discuss network virtualization, its types and why it is required in the IT industry.

What is Network Virtualization?

In network virtualization, the goal is to create an automated central virtual network that has all the features, services and configurations that are crucial for a physical network. Components of such virtual networks include virtual LANs, virtual machines, network interface cards, load balancers, firewalls, servers, and routers, etc. In simple words, network virtualization creates an artificial view of the physical network and presents it to the users.

Network virtualization makes network management an easy and more productive process by performing tasks automatically. This increases the efficiency of even the most complex networks by double as compared to the human administrator based management. Try to virtualize for free you can here, or try demo.

Types of Network virtualization:

  1. External virtualization: in this type of network virtualization, one or more local area networks are either combined or separated into virtual networks to improve the overall performance of a data center or bigger network. External virtualization has two main components i.e. a network switch and a virtual local area network. System administrators can utilize this technology for either configuring a local network’s physically attached systems into separate VLANs or for combining systems of different LANs into a single virtual local network.
  2. Internal virtualization: In this type of network virtualization, software containers i.e. hypervisor programs or VNICs, are used to configure a single system in order to imitate a physical network. By isolating different applications with the help of containers, the efficiency of the system can be improved.


Why the IT industry needs network virtualization?

Implementation of collaborative technologies in data centers has created a demand for sophisticated network infrastructures. Such infrastructures cannot be created using physical networks but virtual networks have everything covered. Some of the main reasons why the IT industry is turning to this technology are listed below:

  1. These networks are cost-effective as they reduce the need for new hardware and utilize existing assets for improving performance.
  2. This technology helps in creating an energy efficient network which requires less power for its services nodes and infrastructure.
  3. Growth can be agile with virtual networks as incremental services can be delivered using the same infrastructure in a short span of time.
  4. Network security and its management can be addressed by keeping user groups with similar service needs separate from other user groups.
