There has been a significant increase in the number of enterprises deploying SDN. There are multiple ways in which SDN has benefitted the enterprises.
FREMONT, CA: Software-Defined Networking (SDN) has emerged as one of the most popular ways for enterprises to deploy applications at a much faster rate and also reduce the total expenses of deployment. SDN provides support to the administrators in managing and provisioning network services from a centralized location. As the requirements of modern businesses are rising, the physical infrastructure is facing skyrocketing challenges to keep up with the pace. This is where virtualized solutions like SDN come into the picture.
SDN offers enterprises an alternative where they are able to upscale their network infrastructure with less disruption. Today giant companies are deploying SDN solutions such as Beacon, Cisco Open SDN Controller, Juniper Contrail, and Brocade SDN Controller.
Following are some advantages of leveraging this technology within an organization:
SDN provides its customers with more scalability. It possesses the capability for provisioning resources at any time, the users have the choice to change the network infrastructure at a moment's notice. The difference in scalability is noticeably remarkable in comparison to traditional network setup, where resources were required to be purchased and configured manually.
2. Reduction in Hardware Footprint
The deployment of SDN enables an administrator to optimize the usage of hardware and work more efficiently. The worker is able to assign active hardware with a new objective at will. This means that the resources can now be shared more comfortably. This eliminates the legacy-driven network where hardware was limited to a single purpose.
3. Centralized Provisioning
One of the main privileges provided by SDN is the potential to manage a network from a centralized point of view. In simple words, SDN enables the users to provision virtual and physical elements from one location by virtualizing both the data and control planes. This has proven to be extremely useful as it was difficult to monitor traditional infrastructure, especially when there are lots of disparate systems that are required to be managed individually. SDN cuts off this barrier and enables the administrator to drill up and down at his own will.
Though the advancement in virtualization has made it more complex for the administrators to safeguard their networks again, cyber crimes, however, have also brought a huge advantage that cannot be ignored. An SDN controller offers a centralized location from which the administrator can control the entire security of the network. While this arrives at the price of making the controller of SDN a target, it also offers the users with a clear picture of their infrastructure. This enables users to manage the security of their complete network.
5. Supporting Cloud-based Traffic
Cloud is one of the emerging trends in IT and Telecom. The Cloud operates in correlation with self-service and on-demand capacity. Hence, it becomes easy for SDN to deliver according to the demand and availability of the resources present in the data center.
An enterprise can benefit much more by leveraging SDN. It is indeed a great fit for various enterprises, IT and service providers, telecom companies, and more.
