I’ve been trying to dig a bit deeper into the European Commission’s investigation of Oracle’s proposed acquisition of Sun Microsystems, to look beyond the received wisdom about the EC’s concerns about the deal.

We know they revolve around the open source MySQL database, the European Commission has said that much. But the Statement of Objections weighs in at 155 pages, and even those that have read it admit to being confused by it. Meanwhile some of the most vocal parties in the public debate have vested interests in encouraging opinions for or against the deal.

Without knowing precisely what the European Commission wants to achieve it is impossible to come to any conclusions about the investigation. However, here are a few statements and observations:

A number of people have recently raised the issue of the threat that cloud computing poses to the monetization of open source by specialist vendors, including Savio Rodrigues, Matt Asay, and Mike Hogan.

I believe that cloud computing provides an opportunity for open source specialists, but agree that cloud services based on open source code could potentially eat into the business opportunities for open source specialists since the cloud providers have no …

On the 18th of November we've hold in Milan an event focused on Open Source Data Warehousing.

For many organizations, data warehouses are simply too costly to buy, too costly to implement and too costly to maintain. Data warehousing is still a luxury of deep-pocketed organizations, although the resulting benefits can be virtually reaped by companies of all sizes.
Open Source Software is changing the rules again, lowering the economic barriers to undertake Business Intelligence and Data Warehousing projects.

During the event we proved that MySQL can help organizations to achieve higher ROI on their projects. With the support of our partners, Infobright and Talend, we showed how to design, deploy and manage a multi-terabyte Data Warehouse with Open Source Software.

Participants have shown a …

Savio Rodrigues has published a post arguing that cloud platforms such as Amazon Web Services and Microsoft’s Azure pose a threat to the monetization of open source by specialist vendors.

Savio makes a good case based on the recent launch of AWS’s Relational Database Service, based on MySQL, and Microsoft’s support for MySQL and Tomcat on Azure:

“When Amazon decided to offer MySQL via Amazon RDS, they did so without purchasing MySQL support from Sun. I’ve confirmed that Microsoft Azure is supporting MySQL on Azure without paying Sun for a MySQL Enterprise subscription.”

Clearly there is a threat to open source vendors from cloud-based services. Meanwhile I have previous …

Since the European Commission announced it was opening an in-depth investigation into the proposed takeover of Sun Microsystems by Oracle with a focus on MySQL there has been no shortage of opinion written about Oracle’s impending ownership of MySQL and its impact on MySQL users and commercial partners, as well as MySQL’s business model, dual licensing and the GPL.

In order to try and bring some order to the conversation, we have brought together some of the most referenced blog posts and news stories in chronological order.

Part one took us from the announcement of the EC’s in-depth investigation up to the eve of the communication of the EC’s Statement of Objections.

Part two, below, takes us from there to the eve of the announcement of Oracle’s concessions. …

Below is a rough draft of the cornerstone slide for a new presentation deck I am putting together to explain the various business strategies for monetizing open source software. The aim is to explain every single existing strategy using the elements on this one slide (although I am yet to test it out).

In our previous discussions about business strategies we have noted that there are four elements that shape a business strategy around open source software: the open source software license; the development strategy; the end user license strategy; and the revenue trigger.

As can be seen from the slide above, I have added a fifth element: copyright control. Copyright was previously considered in our research around business strategies but was seen more as an underlying influence than a distinct strategy element.

I have recently come to the realisation that copyright control is not just a part of each of the four elements, and …
