What does Software-Defined
Anything (SDx) mean?
Software-defined
anything (SDx) is an important yet ambiguous term that refers to new changes happening
in the IT world. It is a movement toward promoting a greater role for software
systems in controlling different kinds of hardware - more specifically, making
software more "in command" of multi-piece hardware systems and
allowing for software control of a greater range of devices.
Explanation According to Techopedia
Experts
explain SDx as a fundamentally connective tool that supports evolving network
topologies. Another way to think about SDx is as an extension of the bring your
own device (BYOD) movement, which is puzzling businesses and security managers.
The BYOD movement essentially opened the control of network data from
conventional workstations to portable smartphones and tablets. A SDx approach
could further open up that field to different types of portable or versatile
devices. However, this approach is also a double-edged sword, as expanding
network capability can generate even greater security gaps, leaving businesses
scrambling to understand how to minimize liability from unauthorized smartphone
or tablet usage.
Some
also link the emergence of a software-defined anything approach to the Internet
of Things (IoT), an emerging philosophy of linking more types of devices and
assets to a global IP network. Generally, this supports the most basic
definition of SDx as a future system, where one set of software rules over
numerous connected machines while directing many different types of user
activity.
