Modern web network and internet telecommunication technology, big data storage and cloud computing computer service business concept: server room interior in datacenter in blue light

We’ve talked about network virtualization on this blog before, but there was some recent confusion over whether or not that service is different from software-defined networking. It’s not a big difference, but no, they’re not the same. 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 IT 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 IT 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.

A virtualized network may sound like an exciting technology that doesn’t have much use at small- or medium-sized business, but that’s exactly the beauty of hiring a managed services provider!
