A logo on a T-shirt and what it stands for​

At this year's TechRiders Festival in Hürth, Germany, three people walked around a tech event in polo shirts carrying the Apache CloudStack logo. Not as a statement. Not as a marketing move. Simply because it is part of who they are and what they do every day.

The recent Apache CloudStack European User Group, held in The Hague on 21 May, was officially recognized as the largest CloudStack User Group event to date. The event brought together cloud builders, researchers, and technology enthusiasts for a full day of technical presentations, knowledge sharing, and engaging community discussions - highlighting the continued growth and momentum of the CloudStack community.
