I was at CloudExpo Europe in London last week for the Open Cloud Forum to give a tutorial on CloudStack tools. A decent crowd showed up, all carrying phones. Kind of problematic for a tutorial where I wanted the audience to install python packages and actually work :) Luckily I made it self-paced so you can follow at home. Giles from Shapeblue was there too and he was part of a panel on Open Cloud. He was told once again "But Apache CloudStack is a Citrix project !" This in itself is a paradox and as @jzb told me on twitter yesterday "Citrix donated CloudStack to Apache, the end". Apache projects do not have any company affiliation.

I don't blame folks, with all the vendors seemingly supporting OpenStack, it does seem that CloudStack is a one supporter project. The commit stats are also pretty clear with 39% of commits coming from Citrix. This number is also probably higher since those stats are reporting gmail and apache as domain contributing 20 and 15% respectively, let's say 60% is from Citrix. But nonetheless, this is ignoring and mis-understanding what Apache is and looking at the glass half empty.

When Citrix donated CloudStack to the Apache Software Foundation (ASF) it relinquished control of the software and the brand. This actually put Citrix in a bind, not being able to easily promote the CloudStack project. Indeed, CloudStack is now a trademark of the ASF and Citrix had to rename their own product CloudPlatform (powered by Apache CloudStack). Citrix cannot promote CloudStack directly, it needs to get approval to donate sponsoring and follow the ASF trademark guidelines. Every committer and especially PMC members of Apache CloudStack are now supposed to work and protect the CloudStack brand as part of the ASF and make sure that any confusion is cleared. This is what I am doing here.

Of course when the software was donated, an initial set of committers was defined, all from Citrix and mostly from the former startup. Part of the incubating process at the ASF is to make sure that we can add committers from other organization and attract a community. "Community over Code" is the bread and butter of ASF and so this is what we have all been working on, expanding the community outside Citrix, welcoming anyone who thinks CloudStack is interesting enough to contribute a little bit of time and effort. Looking at the glass half empty is saying that CloudStack is a Citrix project "Hey look 60% of their commits is from Citrix", looking at it half full like I do is saying "Oh wow, in a year since graduation, they have diversified the committer based, 40% are not from Citrix". Is 40% enough ? of course not, I wish it were the other way around, I wish Citrix were only a minority in the development of CloudStack.

Couple other numbers: Out of the 26 members of the project management committee (PMC) only seven are from Citrix and looking at mailing lists participation since the beginning of the year, 20% of the folks on the users mailing list and 25% on the developer list are from Citrix. We have diversified the community a great deal but the "hand-over", that moment when new community members are actually writing more code than the folks who started it, has not happened yet. A community is not just about writing code, but I will give it to you that it is not good for a single company to "control" 60% of the development, this is not where we/I want to be.

Gluster Community Adds New Members Citrix, Harvard FASRC and Expands Governing Board
Citrix, Harvard University FASRC and long-time contributors join the Gluster Community Board to drive the direction of open software-defined storage

February 5, 2014 – The Gluster Community, the leading community for open software-defined storage, announced today two new organizations have signed letters of intent to join: Citrix, Inc. and Harvard University's Faculty of Arts and Science Research Computing (FASRC) group. This marks the third major expansion of the Gluster Community in governance and projects since mid-2013. Downloads of GlusterFS per month have tripled since the beginning of 2013, and traffic to has increased by over 50% over the previous year. There are now 45 projects on the Gluster Forge and over 200 developers, with integrations either completed or in the works for OpenStack Swift, CloudStack, OpenStack Cinder, Ganeti, Archipelago, Xen, QEMU/KVM, Ganesha, the Java platform, and SAMBA, with more to come in 2014.

Citrix and FASRC will be represented by Mark Hinkle, Senior Director of Open Source Solutions, and James Cuff, Assistant Dean for Research Computing, respectively, joining two individual contributors: Anond Avati, Lead GlusterFS Architect, and Theron Conrey, a contributing speaker, blogger and leading advocate for converged infrastructure. Rounding out the Gluster Community Board are Xavier Hernandez (DataLab); Marc Holmes (Hortonworks), Vin Sharma (Intel), Jim Zemlin (The Linux Foundation), Keisuke Takahashi (NTTPC), Lance Albertson (The Open Source Lab at Oregon State University), John Mark Walker (Red Hat), Louis Zuckerman, Joe Julian, and David Nalley.


Citrix has become a major innovator in the cloud and virtualization markets. They will drive ongoing efforts to integrate GlusterFS with CloudStack ( and the Xen hypervisor. Citrix is also sponsoring Gluster Community events, including a Gluster Cloud Night at their facility in Santa Clara, California on March 18.

If you weren't in Portland last week, you missed a fantastic OSCON. Perhaps the best part (aside from the weather, which - as a St. Louisan, I was deeply grateful for the respite) was the Citrix-sponsored poker party on Thursday night. A lot of people turned up to play a little poker, have a bit of pizza, and partake of some really good Portland beers. Not to mention, trying their hand at winning some of the prizes: 


  • Top prize, a System 76 Gazelle laptop, went to Abigail with more than 28,000 in chips. (Note, participants started the evening with 300 in chips, so... wow.)
  • We also had a prize for the participant who knocked out OSCON co-chair and poker enthusiast, Sarah Novotny. That goes to John Llewellyn, who took the bounty well before the evening was over.
  • The next two runners up, Karen Rustad and Brian Bilek, each receive an Android Galaxy Nexus phone.

Thanks again to everyone who attended - it was a blast! Special thanks to Fedora's Robyn Bergeron, who came up with the idea and for providing Fedora playing cards for the tables and attendees.

Be sure to check out the photos from the event. Big thanks to O'Reilly photographer Pinar Ozger who turned up to get some really good shots of the party. (I also have a few in the gallery, and it's really easy to tell which photos were taken by the professional photographer and which are mine...)

When CloudStack was launched as an open source project back in 2010 our goal was to make CloudStack the leading open source cloud computing platform and to enable our users, partners, and customers to easily use, modify, and contribute to the project. We chose to license the project under the GNU Public License v3 (GPLv3) then.  The reasoning was that this was not only an OSI-approved license but also it allowed us to maintain compatibility with the Apache Software License. At the time it was the right move for the project... but times change.

Today we are announcing our move from the GPLv3 to the Apache License 2.0. We are also planning to apply contribute the CloudStack project to the Apache Software Foundation(ASF) and with their acceptance to turn CloudStack into a truly community run project but with governance provided by the Apache Foundation rather than by Citrix alone.  In addition, Citrix has stepped up its investment in the project and the open source community and decided to become a platinum sponsor of the Apache Foundation. They also will be hiring additional developers, evangelists and providing other resources to help insure the success of the CloudStack project in the long-term.

Why Switch Licenses?

Over the course of the last two years the feedback from our users and partners was that while the GPL was a fine license that it did throw up some roadblocks to their participation and use. Today Citrix has announced their intention to contribute the CloudStack code to the Apache foundation and to license CloudStack 3.0.1 and all future versions under the  Apache Software License.

This decision was not made lightly and frankly when the idea was floated I was a little skeptical as a fan of Linux I was fond of saying, “If the GPL is good enough for Linus, it’s good enough for me.” The problem is that I am only one person and while it was fine for me it was not the license that best served everyone in our community and put up barriers for others to participate.
