It's long been the case that the world of Linux distributions offers at least one compelling choice for virtually every taste and purpose, but -- much like those dissatisfied with the weather in New England -- users who don't see a distro they like need only wait a few minutes. The open source natur...

Linux on the desktop may have missed its adoption time line, but Linux in the cloud is a win-win proposition for the post-PC movement. Microsoft's Azure may be the only real threat to Linux cloud dominance -- all other major cloud software platforms are based on Linux and open source software. Some ...

Smartphones and tablets have become ubiquitous -- and so convenient that we often download apps and approve permissions without giving them much thought.

Systems Performance: Enterprise and the Cloud is a must-have reference guide for any IT manager or sysadmin whose job involves working with computer systems that are tethered to the cloud. Author Brendan Gregg is no newcomer to writing definitive books on computer networks and system perfor...

Insurance companies have always been adamant about spotting and controlling risks. That, after all, is the basis for accepting policyholders and placing them into rate categories.

When open source software was still getting established in the enterprise five years ago or so, there was a lot of discussion about so-called open core ripoffs.

Vendor lock-in has been such a standard part of enterprise IT over the years that it often goes unnoticed and unquestioned. Recently, however, that lock-in mentality has followed enterprises to the clouds. One might not think that vendor lock-in would exist for those who use open source software or ...

We may not see or hear much about open source in the latest cloud or Big Data offerings, but it's playing a significant role in the most disruptive trends in enterprise IT. Just as we've seen with open source in cloud computing, it is an integral part of trends that currently are disrupting consumer...

Cloud storage technologies and Big Data are driving rapid industry growth. Cloud storage developed around three model options: Infrastructure as a Service; Platform as a Service; and Software as a Service.

The discussion and debate over open source cloud software's compatibility with cloud leader Amazon's proprietary APIs was just beginning when the 451 Group released "The OpenStack Tipping Point" in April. With the advancement of the OpenStack software and community -- along with lingering questions ...

Hybrid cloud technology is garnering much attention of late -- whether for cutting-edge development and the continuous integration and release processes achieved through devops, or for traditional enterprise-proven approaches to infrastructure and applications. There's more to hybrid clouds than hyp...

Since its start in the summer of 2010, the OpenStack open source cloud computing project has been the subject of a lot of hype.

DevOps represents a dramatic change from the old siloed developers and script-heavy system administrators of yesterday. Any tools that can provide some common ground for developers and IT operations professionals can help, and it seems Chef and Puppet often do.

The year is starting out with what may turn out to be significant changes in the mobile operating system market, with open source software playing a significant role just as it has in enterprise software, virtualization and cloud computing. With fading heavyweights and interesting new challengers, t...

It's obvious from the latest U.S. election that our voting system could use some improvement in terms of both enabling and supporting voters and efficiently tallying and verifying a trusted result. Open source offers the technology, as well as the culture and community, to address these challenges, ...

The general public knows little about the true technology fundamentals of cloud computing, suggests a recent survey commissioned by IT vendor Citrix. Almost a third of the roughly 1,000 U.S. adults polled thought cloud computing was related to weather. However, the ascendance of Linux and open sourc...

VMware continued its embrace of open source software with its recent acquisition of open source and virtual network provider Nicira. The move continued VMware's aggressive M&A strategy and its effort to transition from proprietary software and virtualization to a broader market and cloud compu...

Just when you thought it couldn't top itself -- having contributed Linux kernel code under the GPL, broadly supported Linux alongside Windows with its systems management and other software, and spun off a new subsidiary dedicated to openness, Microsoft showed yet more Linux and open source love rece...
