How to Help Your Business Become an AI Early Adopter

(Page 1 of 4)

A 2011 Gartner survey found that more than half of all enterprises surveyed had adopted some open source software. However, many businesses also need professional support and related services to make open source software viable for their organizations. Commercial open source software vendors fill in the gap for these businesses by providing those additional services while keeping overall costs low.

In addition to low costs, open source software gives businesses the ability to tailor the software to their specific needs. According to Laurie Wurster, research director at Gartner, "Users are beginning to look at OSS differently — if they can customize the code to make it unique to their company, they have created a competitive advantage." She added, "Although a search for reducing costs by adopting OSS continues to be a major driver, with this survey we see more respondents looking at OSS as having much-greater value than simply getting something for free."

With enterprises in mind, we've updated our list of top commercial open source projects. While home users might be interested in some of this software, the commercial versions are all targeted primarily at business users.

Each of these projects offers at least one version of its software under an open source license, while providing additional software, hardware, support and/or services for a fee. This arrangement allows organizations to receive many of the benefits of open source software, along with the other products and services they need to make the software usable. At the same time, the software developers receive the income they need to continue producing quality software.

As always, if you know of another commercial open source project that you think should be included in our list, please feel free to make a note in the comments section below.
