What is Network Virtualization?
Network virtualization represents the administration and monitoring of an entire computer network as a single administrative entity from a single software-based administrator’s console.
Network virtualization can include storage virtualization, which contains managing all storage as an individual resource. Network virtualization is created to enable network optimization of data transfer rates, flexibility, scalability, reliability, and security. It automates many network management functions, which disguise a network's true complexity. All network servers and services are considered as one pool of resources, which can be used independently of the physical elements.
Virtualization can be defined as making a computer that runs within another computer. The virtual computer, or guest device, is a fully functional computer that can manage the same processes your physical device can. The processes performed by the guest device are separated from the basic processes of your host device. You can run several guest devices on your host device and each one will identify the others as an independent computer.
Advantages of Network Virtualization
The advantages of network virtualization are as follows −
Lower hardware costs − With network virtualization, entire hardware costs are reduced, while providing a bandwidth that is more efficient.
Dynamic network control − Network virtualization provides centralized control over network resources, and allows for dynamic provisions and reconfiguration. Also, computer resources and applications can connect with virtual network resources precisely. This also enables for optimization of application support and resource utilization.
Rapid scalability − Network virtualization generated an ability to scale the network rapidly either up or down to handle and make new networks on-demand. This is a valuable device as enterprises transform their IT resources to the cloud and shift their model to an ‘as a service’.
Types of Network Virtualization
The types of network virtualization are as follows −
Network Virtualization − Network virtualization is a technique of combining the available resources in a network by splitting up the available bandwidth into different channels, each being separate and distinguished.
Server Virtualization − This technique is the masking of server resources. It simulates physical servers by transforming their identity, numbers, processors, and operating frameworks. This spares the user from continuously managing complex server resources. It also makes a lot of resources available for sharing and utilizing, while maintaining the capacity to expand them when needed.
Data Virtualization − This type of cloud computing virtualization technique is abstracting the technical details generally used in data management, including location, performance, or format, in favor of broader access and more resiliency that are directly related to business required.
Application Virtualization − Software virtualization in cloud computing abstracts the application layer, separating it from the operating framework.
