Tight budgets prompt another look at open source. Users say savings and other benefits are easy to reel in, but there are problems, too. We take a look at just what you need to consider with open source.
When it comes to open source software, the cost benefit is one of the most commonly highlighted. However, there are other pros to using the software.
For example, CIO Daniel Chan said cost savings weren't the number one priority for using open-source software.
He was mainly interested in how open source would enable his IT group at the New York State Office of Temporary and Disability Assistance to put ideas into action more quickly.
In his government office, the procurement process lasts anywhere from 12 to 18 months.
"It makes it impossible to do anything creative," Chan says.
With open-source software, it took just a few months for Chan's team to get the tools it needed to build a new self-service benefits system - just in time for the flurry of activity that occurred during the economic freefall.
Even though the agency purchased a support contract for the technology, there were no licencing terms and conditions to negotiate, which cut way back on the involvement of the procurement and legal offices.
And the benefits kept coming. As use of the system escalated, Chan's team not only kept up with the increasing volume, but also was able to help transfer the technology to three other states in a month's time, since there was no commercial licence involved.
"We were able to get people to come in and help quickly because there was a large pool of developers to draw from," Chan says.
With that success, Chan is now looking at migrating from the agency's current Unix platform to Linux - and this time, cost savings are at the fore.
"We'll easily see three to five times in savings by moving to open systems," he says.
"Instead of $5m to do a technology refresh, it will be $1m or less."
In fact, in an survey of 143 IT professionals by PC Advisor's sister title Computerworld, 80 percent of the respondents cited cost savings as the number one benefit of open-source software, and 61 percent said open source has become more accepted in enterprises over the past few years.
Open-source software "has transformed over the last decade from this unknown, risky thing that hippies and garage developers do, to the basis for a market in the billions of dollars", says Jay Lyman, an analyst at The 451 Group.
"It's come of age, and it's just assumed to deliver cost savings."
But the close association of open source and cost savings can lead users to overlook other benefits of open source - and the challenges that might come with it, including the need to manage cultural change, risk and expectations.
"There's a lot to live up to," Lyman says.
"If people discover that it costs more than they thought, you do hear horror stories."
What's more, the decision to use open source has - until recently - been more low-level than strategic, according to Forrester Research.
So while there's executive awareness of the cost advantages, other benefits, potential risks and structural changes required to take full advantage of open source are less well understood.
