SDN is a journey, and it will take time to get there. Companies need a transition period to introduce or extend network virtualization and automation into data center infrastructure. They may need to nurture in-house skill sets and tune operations in other ways to ready themselves for SDN and the digital transformation that underlies it. That education starts by putting the benefits of SDN in context:
1. Centralized network provisioning. Because it abstracts the control and data planes, SDN can load-balance and distribute traffic more efficiently to prevent chock points, which can improve application performance.
2. Comprehensive infrastructure management. Provisioning infrastructure (storage, servers and networks) with a central console for management.
3. Augmented automation. Automation helps create a more predictable, consistent environment and promotes scalability to accommodate peaks and valleys in traffic load.
4. Enhanced security. While virtualization has made management more complex, having a centralized network controller can bring the reins of control back to IT professionals’ hands and create a central point of control to distribute security and policy information consistently throughout the enterprise.
5. Reduced operating costs. Centralized management, operational efficiency and better hardware use all enable reduced costs.
6. Reduced hardware management and costs. You can extend the life of existing hardware because you have shifted the decision making to the SDN controller.
7. Cloud-ready infrastructure. As companies move to the cloud, their infrastructure needs to be virtualized and centrally managed in order for IT professionals to build new services on top of the infrastructure. With a more flexible and scalable IT infrastructure, companies can develop and deploy new applications and services in days rather than weeks or months.
At the same time, as noted, virtualization and centralized management can introduce some new challenges. The onus is on SDN technology providers to keep an eye on the complexity that comes with automation and program ability of the network. Automation can be the foe of simplicity, so SDN technology has to strike the balance between the two.
