Network Virtualization – A Useful Option for Managing Networks and to Make Networks Scalable
There are several benefits of network virtualization
ranging from reduction in expenditure for managing networks (and their associated resources as well as devices) to making a network more scalable and agile. This way you are able to lower the downtime for critical applications and provide better user experience to your customers. In the following sections let us go through few of the main benefits of network virtualization.
Top 6 Benefits of Network Virtualization
- Easy Management
- Quick Provisioning
- Granular Security
- Simpler Troubleshooting
- Development of Cloud Environment
- Less Need for Training and Skills
Network virtualization is one type of overlay based approach which can be helpful in programming as well as provisioning network as per demand, without the need to physically access routers or switches.Moreover, it becomes possible to provide a network within a few seconds instead of few weeks or days as it used to take before network virtualization become popular. Let us now look at few of the other benefits.
Easy Management: Virtualization makes it possible to utilize a management console for managing all the network devices. Moreover, it is not necessary to physically access switches or have skills for managing different types of routers and switches.
Quick Provisioning: Due to the easy programmability of networks, it becomes possible to provision networks within a short period of time. Thus, applications can be deployed quickly.
Granular Security: Using network virtualization it becomes possible to implement access policies and granular security which adhere to compliance requirements. Additionally, you also get the freedom to implement compliance and security on an on-demand basis.
Simpler Troubleshooting: Network troubleshooting can result in significant downtime for critical business applications.
But now with virtualization, you get access to analytics engine which constantly monitors all the networks to provide real-time as well as historical data. Thus, by analyzing this data you can improve accessibility and scalability of applications so that downtime can be reduced.
Development of Cloud Environment:
Cloud environment becomes fully functional when there is a programmable and completely automated infrastructure behind it. Network virtualization
makes it possible to completely automate a network infrastructure by letting you provision and program the network according to security/network policies.
Additionally, it also becomes possible to provision workloads (both physical and virtual) within a few seconds when you are using network virtualization. As such, it becomes possible to build a completely automated hybrid or private cloud environment.
Training and Skills: Another benefit of virtualization is that it reduces the need to train workers to work on different models and brands of hardware present in a setup. As for instance, when any new network hardware is purchased such as a router or switch, then you will not have to invest again on training for your IT staff to install and maintain such hardware equipment.
A Final Note
We can conclude here with a final note that network virtualization is certainly quite useful for business enterprises and makes it easy to manage networks.
