Private or Public Cloud-Virtualization Helps Both


December 14, 2015

In the ongoing debate between whether to choose a public or private cloud, one technology is helping both camps: virtualization.

Virtualization is one way that the public cloud makes itself safe for businesses, as virtualized environments allow several different businesses to share the same hardware infrastructure less dangerously. But on the other end, virtualization also is enabling more businesses to better scale out their private cloud solutions and localized data centers.

With virtualization, businesses are finding that they can both cut down on dedicated hardware when they roll their own cloud or data center, and that virtualization extends the life hardware.

As Christopher Di Biase said in a recent Automation World article, a senior consultant for network and security services at Rockwell Automation, “By virtualizing, you can pull your old apps onto new hardware. If IT goes to Windows 10, you can pull programs forward and gain a lot of time. Most industrial people want to run a program 10 or 11 years before they think about changing anything.”

The ability to extend the life of hardware through virtualization should not be underestimated, especially for businesses that don’t make data centers their primary business. While any such buildout requires dedicated staff and a significant capital investment, private clouds and localized data centers usually do not get updated as frequently as public cloud provider hardware. It is incumbent, therefore, that older harder can last longer.

At the same time, the technology cannot stay still for long. Virtualization bridges the gap by allowing businesses to update without frequent hardware replacement.

The need for less specialized hardware also is a boon for businesses running their own data center stack. Through virtualization, high-performance servers can run several programs at once and also virtualized specialized routers and appliances that otherwise would each need their own server and rack space.

Changing software is infinitely easier than adding and modifying hardware configurations. Virtualization makes this shift from hardware to software in the data center possible.

Whether public or private cloud, virtualization plays an important role in today’s computing infrastructure. And this is good for business, no matter the mix.

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.
