How does IBM’s open source strategy compare to Sun’s? Or Microsoft’s? What’s the difference between MySQL’s strategy and JasperSoft’s? Are some strategies better suited to engaging with organic open source communities, rather than inorganic? What on earth is the Open Core model?

These are some the questions we hoped to try and address with our Open Source is Not a Business Model report, published in October last year. As I mentioned yesterday, however, without an agreed set of definitions and a common vocabulary it is difficult for a broader understanding the implications of the various models to develop.

One of the ways we might be able to do that is to map the categories we used in our …

Yesterday Sun introduced Glassfish Portfolio. Its a new stack of open source middleware products including Glassfish Enterprise Server, Glassfish ESB, Glassfish Web Space Server, and the new Glassfish Web Stack, which includes support for projects such as Tomcat, Memcached, Apache, PHP, Ruby and Python and a copy of MySQL Community.

It’s a pretty complete infrastructure stack. What it is not, however, is an integrated LAMP stack, despite Sun’s reference to it as such not once but twice on its press announcement.

Glassfish Portfolio runs on Linux of course, as well as Solaris, but it does not contain Linux (integrated or otherwise) or Linux services (although that is available …

There was a rush of new appointment and departure announcements this week. As already noted today, Sun has confirmed the departure of Marten Mickos as Sun is combining its Software Infrastructure organization with its Database Group to form a unified open source product group under the leadership of Karen Tegan Padir, vice president of MySQL & Software Infrastructure.

Earlier in the week Monty Widenius confirmed that he has left Sun, along with …

I just got news that Marten Mickos, former MySQL CEO, is to depart Sun amid a reorganisation of its infrastructure and database business units. Don’t expect an announcement from Sun on this, but the news is confirmed.

It seems that Sun is combining its Software Infrastructure organization with its Database Group to form a unified open source product group under the leadership of Karen Tegan Padir, vice president of MySQL & Software Infrastructure.

Marten will be transitioning out of Sun by the end of the company’s (current) third quarter.

Marten’s departure is a big loss for Sun and follows quickly after the departures of Monty Widenius and …

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:

“You …

Sun reports second quarter results. Compiere reports 216% quarterly revenue growth. EnterpriseDB grows customers accounts. Hyperic and JasperSoft team up on BI for IT. Microsoft embraces Apache but resists GPL. And more.

Sun up or Sun down?
There was some comparatively good news from Sun, which reported a net loss of $209m on revenue down 10.9% at $3.2bn. As Sam Diaz at ZDnet notes, however, “after excluding one-time costs related to recent layoffs and other costs, the company posted a profit of 15 cents per share, beating analysts’ expectations of a 10 cent loss”. In regular trading, shares of Sun were up more than 5%.

Matt Asay noted the impact open …

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 …

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 …

When Monty Widenius published his criticisms of MySQL 5.1 recently a lot of the coverage that followed focused on his belief that the product had been made generally available too early and has too many serious bugs.

A solution to this problem would have been told hold 5.1 back even longer for more testing or, better still, not to have announced it as a release candidate so early. However, reading Monty’s post in full indicates that this would be a matter of treating the symptoms rather than finding a cure.

He also wrote: “the MySQL current development model doesn’t in practice allow the MySQL community to participate in the development of the MySQL server” and “I think it’s time to seriously review how the MySQL server is being developed and change the development model to be more like Drizzle and …
