Can Marten Mickos capture open source lightning in a bottle — twice? He previously built MySQL into an estimated $100 million open source database company that Sun ultimately acquired for $1 billion. Now, Mickos is stepping into the CEO role at Eucalyptus Systems, the open-source cloud platform provider.

Former MySQL boss Marten Mickos says there's still "more to develop and more territory to conquer", and predicts Microsoft will "become one of the biggest friends of open source".

"I am very passionate about open source. And I do believe that it is a superior method. But at the same time, I must be pragmatic. So when they say being dogmatic is very important for the Free Software Foundation -- well, they should be. That's what we respect them for. But running a business is not about dogma," said MySQL CEO Mårten Mickos.

Marten Mickos – the former MySQL chief executive who now heads build-you-own-cloud outfit Eucalyptus Systems – has defended the Eucalyptus platform against recent criticism of both its "open core" model and its ability to scale beyond a relatively small number of servers.

Most Mac lovers love the Mac for the carefully wrought user interfaces and the crisp design, and never pay attention to the open source at the heart of the operating system. But underneath this beautiful facade is a heart built upon the rich -- if often chaotic -- world of open source software.

A survey of 118 enterprise IT and development executives conducted by open source solution provider OpenLogic concludes that the "Open Core" model for open source licensing trails behind dual licensing and open source with commercial support, in terms of acceptability to the enterprise.

Most software developers have little interest in entrepreneurship, but an open-source software project will survive and thrive only by delivering value into a market (users) with business partners (contributors) and against competitors (other open and closed source software). If you want to run a successful open-source project, it helps if you consider the key questions that apply when defining a commercial business model. I'll expand on Chesbrough's and Rosenbloom's list of 6 themes to demonstrate why.

OpenITWorks CEO Michael Grove contends that it is a mistake to think of commercial open source as its own business model. Instead, open source is one of many possible means to an end of making a single software business model successful -- that of selling value to customers through software. Businesses should focus their strategic planning on how to best monetize their value propositions, through open source or something else.
