Open source is creating more business opportunities rather than limiting them, even if the software itself is given away, said Kim Polese, CEO of SpikeSource.“In fact, I see open source [as] driving an incredible renaissance right now,” she said in an interview on Wednesday at LinuxWorld Conference & Expo in San Francisco.“There are more opportunities being founded,” she said. Open source business models generally involve selling subscriptions to technical support services. Another business model that does not involve selling software is the hosted model, in which software is hosted and accessed via the Web with advertising providing revenues, such as what Google has done. When software is given away, a community forms around it, Polese said. Developers of this software can then build a commercial business. She cited as an example Bryght , which formed around the Drupal project for open source content management.SpikeSource provides access to open source stacks and certifies them across multiple operating systems. Patch management and support services also are featured. Technology Industry
