Many people wonder what the difference between Virtualized Networks and SDN (Software-Defined Networks). Let’s take a look at what sets them apart.

Software-defined networking (SDN)

Managing storage, infrastructures, and networks with high-level software is something I.T. technicians have been doing for a long time. It’s a subset of virtualization and it is one of the oldest strategies for optimizing and securing your I.T. hardware.

Despite its popularity, SDN does have one major drawback — it needs hardware to do its job. SDN allows you to control network switches, routers, and other peripherals from a centralized software platform, but you can’t create virtual segments of your network without the hardware that would normally be required outside of an SDN environment.

Network virtualization

Evolving beyond SDN was inevitable. Whenever a technology can’t do it all, you can bet someone is working hard to fix that. Network virtualization uses advanced software solutions to allow administrators to manage physical hardware and to create virtual replicas of hardware that are indistinguishable to servers and workstations.

Network virtualization simplifies the field of network design. You can reduce spending on expensive hardware, reconfigure network segments on the fly, and connect physically separate networks as if they were in the same room.

Let’s hope that cleared things up. Contact us to learn more about how these solutions can benefit your business.
