The breadth that its taken on is all encompassing, Marinaccio notes. A few years ago there were early adopters, especially in the financial area and in the energy sector. And now its very widespread.
Over the last 6 to 12 months, he has gotten calls from plenty of companies just getting on board with Linux. For example, smaller firms in the Midwest who have been testing Linux as a platform and have now fully switched over. And open source continues to grow in its traditional areas of strength like set top boxes and mobile computing. Its hot in anything calling for a RTOS (real time operating system).
Essentially its moved in to most everything.
Those companies migrating from Solaris to Linux a common shift these days dont need to hire an entirely new crew. The existing Solaris experts can make the switch. Yet that company might want a couple Linux experts on staff who know all the differences between those kissing cousins, Unix and Linux.
Although Marinaccios firm handles system administration jobs, at this point its comparatively rare for a sys admin job to require an exclusive Linux focus. Todays companies have patchwork datacenters, combining Solaris, Windows, Linux and assorted legacy OSes. Overseeing this disparate quilt doesnt necessarily call for a Linux specialist. (Or, a company seeking such a broad-based administrator probably wouldnt hire Hot Linux Jobs to find him.)
Companies see the value of hiring open source experts because shrink-wrapped software is becoming a thing of the past. To gain competitive advantage, they want to tweak and twist their software to wring the highest performance from it. Companies want the customization process to be a constant. Like a financial services company, for whom executing a trade 1/100 of a second sooner could mean big bucks. Or Google, trying to propel its global network of Linux servers to produce still faster search results.
This malleability, and open sources group nature with a transparent architecture that invites mass participation have awoken corporate understanding that Linux staffers can create revenue.
The beauty of it being open is that hopefully, as time goes on, you have all these heads that are collaborating and you go beyond the economies of scale of any one company to come up with a superior product, Maraniaccio says.
H-1B Issues Affecting Linux Salaries
Linux and open source is far more prevalent outside the U.S. than in America. Windows decades-long hold on the desktop prompts U.S. IT managers to lean toward American giant Microsoft a preference not shared by their colleagues around the globe.
