SDN (Software Defined Networking) – GIGABYTE Global

Why do you need it?

Perhaps the most compelling advantage of SDN is that it provides a centralized “intelligent” entity with an entire view of the network, and can make routing and switching decisions based on this view. This centralized entity can control everything, such as changing policies to simplifying configuration and automation across the whole network.

Network resources can therefore be better and more effectively allocated, and since software is used to control the network it is more agile, easier to manage and ready to adapt to whatever use cases emerge in the future. New networks and services can be spun up and down dynamically, and fine-tuned for specific applications.

SDN can also be used to enhance network security by segmenting network traffic – some networks can be ultra-secure and carry sensitive data, while others can be public facing. If a hacker can gain access to a public facing web server, they are restricted only to that segment of the network, and cannot access other segments such as secure data center networks. And all of this can be performed on the same underlying physical network infrastructure to reduce costs.
