Although many businesses are moving towards digitization and automation, IT is not keeping pace. Moreover, many IT departments are undertaking these challenges with the approaches, processes, and tools developed over a decade ago. They are still manually configuring their systems, thereby creating a significant risk for downtime. By some estimates, over 70% of network failures are due to human error.
Today, SDN is more than just a way to use software to automate networking operations. SDN has evolved to include modeling, orchestration, and have become declarative. Meaning, software is performing many of the tasks and underlying processes that were once manual functions, thereby reducing risk and improving efficiency.
Many in the industry confuse SDN with Network Function Virtualization (NFV). Telecoms use NFV to accelerate the development and deployment of network services sometimes called virtual network functions (VNFs). Whereas, SDN uses software to centralize the control of the overall network.
Traditionally telecoms would deploy network fabrics to deliver high-performance, low-latency solutions to converge compute, storage, and software resources within their data or operations centers. SDN is largely used as a programmable abstraction layer tied to the needs of the applications to ensure performance, throughput, and accuracy.
Some of the main benefits Telecoms receive from deploying SDN include:
With the emergence of orchestration and modeling solutions, combined with advances in cloud migration and deployment tools, we are quickly moving into a world where applications, services, storage, and compute will simply declare their requirements. SDN and/or other management solutions will simply spin-up the necessary network requirements to bring these services to life allowing admins to focus on what they do best. This is the era of Big Software.
