Enterprise ICT Improvement through SDN and NFV

By Joe Rizzo December 08, 2015

Anyone who has set up network departments and datacenters knows how difficult it is to maintain numerous systems, services and functions. Information and communications technology (ICT) departments that deal with any communication device or application, such as cell phones, computer and network hardware and software, satellite systems, as well as the various services and applications associated with them, need a better way to efficiently deal with the complexity of legacy systems.

The solution is Software-Defined Networking (SDN) and Network Functions Virtualization (NFV). As these technologies continue to mature and evolve, they are most often seen as two separate, mutually exclusive entities. The fact of the matter is that SDN and NFV are more complementary than we imagine, and can work together to transform corporate networks.

A current report from Research and Market estimates that adoption of these two technologies will grow by as much as 60 percent over the next five years, building to a $1.7 billion market. The study likens the SDN and NFV revolution in enterprise ICT to the effects of SaaS and PaaS on applications.

One of the biggest advantages of SDN and NFV is simplification of provisioning new services. Since the management of unlimited network devices and their ownership is simplified, it becomes much easier to maintain and deploy services, while at the same time increasing security.

Security is improved because ICT departments can create more organized and streamlined security policies. Additionally, they have the ability to patch threats more quickly and reduce the human error factor which has been known to lead to costly data breaches.

Because everything is organized through software and physical connections do not need to be established, SDN and NFV make it easier to set up remote offices and locations. This alone has the added benefit of reducing the amount of time it takes to create network security policies and configure multiple devices, which keeps the workflow moving along uninterrupted. In turn, companies will also realize cost savings.

The flexibility and scalability that can come from incorporating SDN and NFV into the corporate ICT department is something that will be welcomed. As more companies adopt bring your own device (BYOD) policies and establish remote offices, it becomes more difficult to maintain legacy systems requiring equipment and maintenance.

SDN and NFV solutions simplify dynamic networking, real-time and application-centric resource allocation. These technologies promote network automation, in terms of detecting and resolving potential bottlenecks. When you add the network security and cost savings into the equation, you can see why embracing both technologies could be a benefit to any company.
