When The VAR Guy launched his website in January 2008, our resident blogger kept a super close eye on open source channel partner programs. At one point, The VAR Guy published the Open Source 50 — tracking how the top open source companies were working with VARs and IT service providers. So whatever happened to each of the 50 companies in that annual list?

Some are dead, some are thriving, and many have repositioned for cloud computing, Big Data and other buzz words. Here’s a belated update from The VAR Guy in alphabetical order…

1. Acquia: The Drupal specialist still has a partner program for service providers, and Drupal’s popularity as a content management platform has grown extensively.

2. Actuate: Still focused on the Eclipse BIRT (Business Intelligence and Reporting Tools) open source project.

3. Alfresco Software Inc.: Still promoting itself as the leading open source alternative to enterprise content management. Now managing more than 6.6 million users and 3.3 billion documents worldwide.

4. Astaro Corp.: Once positioned as an a unified threat management (UTM) system that leveraged open source. Now owned by Sophos, the endpoint security and anti-virus company.

5. Canonical: The Ubuntu promoter has pushed beyond desktop Linux to promote server and cloud options for channel partners and customers. Still a well-known name, but the rise of tablets and smartphones running Apple iOS and Google Android seems to have stolen some of Ubuntu’s spotlight. Memo to Director of Communications Gerry Carr: Let’s catch up.
