I received an email from Tarus Balog, CEO of OpenNMS Group, on Friday, taking issue with the language I had used to describe two open source vendors (and I use that term deliberately).

Essentially Tarus objected to me using the term “open source vendor” to describe two companies with Open Core licensing strategies. His email raises a valid point about how we determine which companies are considered “open source vendors” and I wanted to use the opportunity to outline the rules I use to make that decision.

As a technical snafu at our end had prevented Tarus from leaving a comment on the blog I hope he won’t mind me using his words to explain the issue he raised.

He wrote:

Wikimedia Foundation is expanding Wikipedia to multimedia with Sun Open Storage Solution and MySQL Database:

Wikipedia receives between 25,000 and 60,000 page requests per second, depending on the time of day. Wikimedia needed to update its infrastructure to handle this huge volume of traffic and ensure that its systems were reliable, highly available, and easily scalable. It also wanted to expand its upload file limit from 20 MB to 100 MB to accommodate rich media (audio and video) content, but before it could do that it needed to expand its storage capacity.

I wrote last week about the commercial open source business strategies that I expect to dominate in 2009.

The flipside to that is the commercial open source community strategy. You simply can’t have one without the other, and I expect community strategies will be a hot topic in 2009 and beyond.

Savio Rodrigues wrote recently that “By the end of 2008, virtually every successful open source vendor has a fairly tightly controlled development process and this hasn’t hurt their revenue growth.”

Based on my prediction that proprietary licensing strategies will be increasingly important in the next two years I am inclined to agree with him.

However, I am also …

I’ve been thinking about the business of what’s variously come to be called commercial open-source and enterprise open-source. I’m interested in the gestalt — the product, development processes, marketing, licensing and so on.

Back in October last year a corporate accountability group called As You Sow attempted to persuade Oracle to detail its commitment to open source by publishing an Open Source Social Responsibility Report.

Oracle resisted the proposal but did promise to share more details on its use of open source in the next version of its Oracle’s Commitment social responsibility report. I just noticed that the renamed Oracle Corporate Citizenship Report (Pdf) was recently published (in late November as far as I can make out) and does indeed include a section on Oracle’s commitment to open source.

In the section “Open Source and Accessibility” Oracle notes that …
