Network virtualization is a computing term used to mean the procedure that separates the management plane from the control panel by combining hardware and software network resources into a single software-based administrative entity. It is used in combination with software containers. It is considered important as it helps stimulate the functionality of traditional hardware. On the same note, software virtualization is useful in creating network overlays. These are the layers of network abstraction that run on top of the physical network.
Many questions are derived from the topic of network virtualization. One is what makes it a great resource for developers and, the second is why you should virtualize your network. Below is an overview of the top benefits of network virtualization.
Boost IT Productivity
Network virtualization is a sure way to scale down the cost of purchasing and maintaining hardware. It usually works best for organizations with bursty workloads that do not require over-provisioning to keep up with the demand. This provision increases data and, speed gives security teams a chance to maintain better network visibility.
Improved Security and Recovery Times
With network virtualization, organizations can control the types of traffic that go through their network. Most of the attackers rely on the fact that once they have breached the security perimeter, there will be few if any security controls are in place. Network virtualization combats this by creating perimeters within the network that are hard to breach. This ability is known as micro-segmentation where sensitive data is placed within a certain virtual network that only allows authorized access.
Quicker Application Delivery
Without network virtualization, network provisioning turns out to be very manual and time-consuming. As a result, every time an application needs to be completed, the disposition time is extended. More to this, without it the possibility of deployment failure increases. Unlike in manual disposition network virtualization automates the configuration process. This helps reduces the deployment time from weeks to minutes. In overall, this allows faster new product roll outs and advanced application updates.
The need to virtualize a network goes undisputed. Through the process most of the tasks that were previously being completed manually become automated. This makes it much easier to scale the network and increase flexibility in completing the functions. Through it, companies are sure to make a milestone by ensuring simplicity, speed, agility, and security. The benefits mentioned above and many others make network virtualization the primary need for running a successful data center network.
