Open-source software in the data center

There is a place for it, but it won't do everything.

In fact, cost is not the major factor at Opus. "We often look to open-source projects as a way to get our feet wet with a specific technology so we can see if a product type meets our needs and the needs of our clients without spending money on the corresponding commercial solutions," Sherwood says. Currently Opus is looking at open-source products for SAN functionality, network management and network control.

Open source is also a way to solve a problem, add a new service or perform some other function that has not yet been budgeted for, or "has not been proven as truly useful and worth pursuing," he says.

Because open-source projects, in general, "do not move forward at the pace of the commercial packages," Sherwood says, his company was looking at more development costs to add functionality or change open-source packages to meet its own needs. So one "hidden cost" of open source, he says, is what it takes internal developers or outside contractors to modify an open-source package. However, in some situations, "commercial offerings are far too costly or lack the necessary functionality required and, therefore, are not a good value. In these cases, open source may be a good solution."

Still, for the foreseeable future, most observers say that open-source will coexist with proprietary packages in the data center.

"As [open-source] packages become more reliable and feature-rich, their popularity will undoubtedly grow among businesses attracted to the relatively low cost of implementation," say EMA's Brasen. "It's unlikely, however, that open-source solutions will completely replace commercial products."

Windows 10 for Business / Dell XPS

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Mark Escubio

Windows 10 / Lenovo Yoga

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
