Getting to Havana

October 18, 2013 1 comment

Yesterday, as the final conclusion of the 6-month “Havana” development cycle, we released the latest version of OpenStack, the 2013.2 version. It’s now composed of 9 integrated components, which saw the completion of more than 400 feature blueprints and the fixing of more than 3000 reported bugs.

As always, it’s been an interesting week for me. Not as busy as you’d think, but lots of hours, day or night, spent frantically checking dashboards, collecting input from our fearful technical leads, waiting for a disaster to happen and pushing the right buttons at the right moment, finally aligning the stars and releasing everything on time. Yes, I use checklists to make sure I don’t overlook anything:




Even if I have plenty of free time between those key hours, I can’t concentrate on getting anything else done, or get something else started (like a blog post). This is why, one day after release, I can finally spend some time looking back on the last stage of the Havana development cycle and see how well we performed. Here is the graph showing the number of release-critical bugs logged against various components (those observing the common feature freeze) as we make progress towards the final release date:




Personally I think we were a bit late, with RC1s globally landing around October 3 and RC2s still being published around October 15. I prefer when we can switch to “respin only for major regressions and upgrade issues” mode at least a week before final release, not two days before final release. Looking at the graph, we can see where we failed: it took us 11 days to get a grip on the RC bug count (either by fixing the right issues, or by stopping adding new ones, or by refining the list and dropping non-critical stuff). Part of this delay is due to stress recovery after a rather eventful feature freeze. Part of it is lack of prioritization and focus on the right bugs. The rest of the graph pretty much looks like the Grizzly one. We were just at least one week too late.

We’ll explore ways to improve on that during the Icehouse Design Summit in Hong-Kong. One solution might be to add a week between feature freeze and final release. Another solution would be to filter what gets targeted to the last milestone to reduce the amount of features that land late in the cycle, to reduce FeatureFreeze trauma. If you want to be part of the discussion, join us all in Hong-Kong in 18 days !

An history of OpenStack open source project governance

June 20, 2013 Leave a comment

Over the last 3 years, the technical governance of the OpenStack open source project evolved a lot, and most recently last Tuesday. As an elected member of that governance body since April 2011, I witnessed that evolution from within and helped in drafting the various models over time. Now seems like a good time to look back in history, and clear a few misconceptions about the OpenStack project governance along the way.


The project was originally created by Rackspace in July 2010 and seeded with code from NASA (Nova) and Rackspace (Swift). At that point an initial project governance was set up. There was an Advisory Board (which was never really created), the OpenStack Architecture Board, and technical committees for each subproject, each lead by a Technical Lead. The OpenStack Architecture Board had 5 members appointed by Rackspace and 4 elected by the community, with 1-year to 3-year (!) terms. The technical leads for the subprojects were appointed by Rackspace.

By the end of the year 2010 the Architecture Board was renamed Project Oversight Committee (POC), but its structure didn’t change. While it left room for community input, the POC was rightfully seen as fully controlled by Rackspace, which was a blocker to deeper involvement for a lot of the big players in the industry.

It was a danger for the open source project as well, as the number of contributors external to Rackspace grew. As countless examples prove, when the leadership of an open source project is not seen as representative of its contributors, you face the risk of a revolt, a fork of the code and seeing your contributors leave for a more meritocratic and representative alternative.


In March 2011, a significant change was introduced to address this perceived risk. Technical leads for the 3 projects (Nova, Swift, and Glance at that point) would from now on be directly elected by their contributors and called Project Technical Leads (PTLs). The POC was replaced by the Project Policy Board (PPB), which had 4 seats appointed by Rackspace, 3 seats for the above PTLs, and 5 seats directly-elected by all the contributors of the project. By spring 2012 we grew to 6 projects and therefore the PPB had 15 members.

This was definitely an improvement, but it was not perfect. Most importantly, the governance model itself was still owned by Rackspace, which could potentially change it and displace the PPB if it was ever unhappy with it. This concern was still preventing OpenStack from reaching the next adoption step. In October 2011, Rackspace therefore announced that they would set up an independent Foundation. By the summer of 2012 that move was completed and Rackspace had transfered the control over the governance of the OpenStack project to the OpenStack Foundation.

The TC

At that point the governance was split into two bodies. The first one is the Board of Directors for the Foundation itself, which is responsible for promoting OpenStack, protecting its trademark, and deciding where to best spend the Foundation’s sponsors money to empower future development of OpenStack.

The second body was the successor to the PPB, the entity that would govern the open source project itself. A critical piece in the transition was the need to preserve and improve the independence of the technical meritocracy. The bylaws of the Foundation therefore instituted the Technical Committee, a successor for the PPB that would be self-governed, and would no longer have appointed members (or any pay-to-play members). The Technical Committee would be completely elected by the active technical contributors: a seat for each elected PTL, plus 5 directly-elected seats.

TC 2.0

The TC started out in September 2012 as an 11-member committee, but with the addition of 3 new projects (and the creation of a special seat for Oslo), it grew to 15 members in April 2013, with the perspective to grow to 18 members in Fall 2013 if all projects applying for incubation recently get finally accepted. With the introduction of the “integrated” project concept (separate from the “core” project concept), we faced the addition of even more projects in the future and committee bloat would inevitably ensue. That created a potential for resistance to the addition of “small” projects or the splitting of existing projects (which make sense technically but should not be worth adding yet another TC seat).

Another issue was the ever-increasing representation of “vertical” functions (project-specific PTLs elected by each project contributors) vs. general people elected by all contributors. In the original PPB mix, there were 3 “vertical” seats for 5 general seats, which was a nice mix to get specific expertise but overall having a cross-project view. With the growth in the number of projects, in the current TC we had 10 “vertical” seats for 5 general seats. Time was ripe for a reboot.

Various models were considered and discussed, and while everyone agreed on the need to change, no model was unanimously seen as perfect. In the end, simplicity won and we picked a model with 13 directly-elected members, which will be put in place at the Fall 2013 elections.

Power to the active contributors

This new model is a direct, representative model, where if you recently authored a change for an OpenStack project, you get one vote, and a chance every 6 months to choose new people to represent you. This model is pretty flexible and should allow for further growth of the project.

Few open source projects use such a direct governance model. In Apache projects for example (often cited as a model of openness and meritocracy), the oversight committee equivalent to OpenStack’s TC would be the PMC. In most cases, PMC membership is self-sustaining: existing PMC members ultimately decide, through discussions and votes on the private PMC list, who the new PMC members should be. In contrast, in OpenStack the recently-active contributors end up being in direct control of who their leaders are, and can replace the Technical Committee members if they feel like they are not relevant or representing them anymore. Oh, and the TC doesn’t use a private list: all our meetings are public and our discussions are archived.

As far as open source projects governance models go, this is as open, meritocratic, transparent and direct as it gets.

The need for releases

April 11, 2013 Leave a comment

The beginning of a new release cycle is as good as any moment to question why we actually go through the hassle of producing OpenStack releases. Twice per year, on a precise date we announce 6 months in advance, we bless and publish source code tarballs of the various integrated projects in OpenStack. Every week we have a meeting that tracks our progress toward this common goal. Why ?

Releases vs. Continuous deployment

The question is particularly valid if you take into account the type of software that we produce. We don’t really expect cloud infrastructure providers to religiously download our source code tarballs every 6 months and run from that. For the largest installations, running much closer to the master branch and continuously deploy the latest changes is a really sound strategy. We invested a lot of effort in our gating systems and QA automated testing to make sure the master branch is always runnable. We’ll discuss at the OpenStack Summit next week how to improve CD support in OpenStack. We backport bugfixes to the stable branches post-release. So why do we continue to single out a few commits and publish them as “the release” ?

The need for cycles

The value is not really in releases. It is in release cycles.

Producing OpenStack involves the work of a large number of people. While most of those people are paid to participate in OpenStack development, as far as the OpenStack project goes, we don’t manage them. We can’t ask them to work on a specific area, or to respect a given deadline, or to spend that extra hour to finalize something. The main trick we use to align everyone and make us all part of the same community is to have a cycle. We have regular milestones that we ask contributors to target their features to. We have a feature freeze to encourage people to switch their mindset to bugfixing. We have weekly meetings to track progress, communicate where we are and motivate us to go that extra mile. The common rhythm is what makes us all play in the same team. The “release” itself is just the natural conclusion of that common effort.

A reference point in time

Singling out a point in time has a number of other benefits. It’s easier to work on documentation if you group your features into a coherent set (we actually considered shortening our cycles in the past, and the main blocker was our capacity to produce good documentation often enough). It’s easier to communicate about OpenStack progress and new features if you do it periodically rather than continuously. It’s easier to have Design Summits every 6 months if you create a common brainstorm / implementation / integration cycle. The releases also serve as reference points for API deprecation rules, for stable release maintenance, for security backports.

If you’re purely focused on the software consumption part, it’s easy to underestimate the value of release cycles. They actually are one of the main reasons for the pace of development and success of OpenStack so far.

The path forward

We need release cycles… do we need release deliverables ? Do we actually need to bless and publish a set of source code tarballs ? My personal view on that is: if there is no additional cost in producing releases, why not continue to do them ? With the release tooling we have today, blessing and publishing a few tarballs is as simple as pushing a tag, running a script and sending an email. And I like how this formally concludes the development cycle to start the stable maintenance period.

But what about Continuous Deployment ? Well, the fact that we produce releases shouldn’t at all affect our ability to continuously deploy OpenStack. The master branch should always be in good shape, and we definitely should have the necessary features in place to fully support CD. We can have both. So we should have both.

Grizzly, the day after

April 5, 2013 2 comments

The OpenStack Grizzly release of yesterday officially closes the Grizzly development cycle. But while I try to celebrate and relax, I can’t help from feeling worried and depressed on the hours following the release, as we discover bugs that we could have (should have ?) caught before release. It’s a kind of postpartum depression for release managers; please consider this post as part of my therapy.


We’d naturally like to release when the software is “ready”, “good”, or “bug-free”. Reality is, with software of the complexity of OpenStack, onto which we constantly add new features, there will always be bugs. So, rather than releasing when the software is bug-free, we “release” when waiting more would not really change the quality of the result. We release when it’s time.

In OpenStack, we invest a lot in automated testing, and each proposed commit goes through an extensive set of unit and integration tests. But with so many combinations of deployment options, there are still dark corners that will only be explored by users as they apply the new code to their specific use case. We encourage users to try new code before release, by publishing and making noise about milestones, release candidates… But there will always be a significant number of users who will not try new code until the point in time we call “release”. So there will always be significant bugs that are discovered (and fixed) after release day.

The best point in time

What we need to do is pick the right moment to “release”: when all known release-critical issues are fixed. When the benefits of waiting more are not worth the drawbacks of distracting developers from working on the next development cycle, or of abandoning the benefits of a predictable time-based common release.

That’s the role of the Release Candidates that we produce in the weeks before the release day. When we fixed all known release-critical bugs, we create an RC. If we find new ones before the release day, we fix them and regenerate a new release candidate. On release day, we consider the current release candidates as “final” and publish them.

The trick, then, is to pick the right length for this feature-frozen period leading to release, one that gives enough time for each of the projects in OpenStack to reach this the first release candidate (meaning, “all known release-critical bugs fixed”), and publish this RC1 to early testers. For Grizzly, it looked like this:


This graph shows the number of release-critical bugs in various projects over time. We can see that the length of the pre-release period is about right: waiting more would not have resulted in a lot more bugs to be fixed. We basically needed to release to get more users to test and report the next bugs.

The Grizzly is still alive

The other thing we need to have is a process to continue to fix bugs after the “release”. We document the most obvious regressions in the constantly-updated Release Notes. And we handle the Grizzly bugs using the stable release update process.

After release, we maintain a branch where important bugfixes are backported and from which we’ll publish point releases. This stable/grizzly branch is maintained by the OpenStack stable maintenance team. If you see a bugfix that should definitely be backported, you can tag the corresponding bug in Launchpad with the grizzly-backport-potential tag to bring it to the team’s attention. For more information on the stable branches, I invite you to read this wiki page.

Being pumped up again

The post-release depression usually lasts a few days, until I realize that not so many bugs were reported. The quality of the new release is actually always an order of magnitude better than the previous releases, due to 6-month worth of improvements in our amazing continuous integration system ! We actually did an incredible job, and it will only get better !

The final stage of recovery is when our fantastic community gets all together at the OpenStack Summit. 4 days to witness and celebrate our success. 4 days to recharge the motivation batteries, brainstorm and discuss what we’ll do over the next 6 months. We are living awesome times. See you there.

UDS is dead, long live ODS

March 4, 2013 1 comment

Back from a (almost) entirely-offline week vacation, a lot of news were waiting for me. A full book was written. OpenStack projects graduated. An Ubuntu rolling release model was considered. But what grabbed my attention was the announcement of UDS moving to a virtual event. And every 3 months. And over two days. And next week.

As someone who attended all UDSes (but one) since Prague in May 2008, as a Canonical employee then as an upstream developer, that was quite a shock. We all have fond memories and anecdotes of stuff that happened during those Ubuntu developer summits.

What those summits do

For those who never attended one, UDS (and the OpenStack Design Summits that were modeled after them) achieve a lot of goals for a community of open source developers:

  1. Celebrate recent release, motivate all your developer community for the next 6 months
  2. Brainstorm early ideas on complex topics, identify key stakeholders to include in further design discussion
  3. Present an implementation plan for a proposed feature and get feedback from the rest of the community before starting to work on it
  4. Reduce duplication of effort by getting everyone working on the same type of issues in the same room and around the same beers for a few days
  5. Meet in informal settings people you usually only interact with online, to get to know them and reduce friction that can build up after too many heated threads

This all sounds very valuable. So why did Canonical decide to suppress UDSes as we knew them, while they were arguably part of their successful community development model ?

Who killed UDS

The reason is that UDS is a very costly event, and it was becoming more and more useless. A lot of Ubuntu development happens within Canonical those days, and UDS sessions gradually shifted from being brainstorming sessions between equal community members to being a formal communication of upcoming features/plans to gather immediate feedback (point [3] above). There were not so many brainstorming design sessions anymore (point [2] above, very difficult to do in a virtual setting), with design happening more and more behind Canonical curtains. There is less need to reduce duplication of effort (point [4] above), with less non-Canonical people starting to implement new things.

Therefore it makes sense to replace it with a less-costly, purely-virtual communication exercise that still perfectly fills point [3], with the added benefits of running it more often (updating everyone else on status more often), and improving accessibility for remote participants. If you add to the mix a move to rolling releases, it almost makes perfect sense. The problem is, they also get rid of points [1] and [5]. This will result in a even less motivated developer community, with more tension between Canonical employees and non-Canonical community members.

I’m not convinced that’s the right move. I for one will certainly regret them. But I think I understand the move in light of Canonical’s recent strategy.

What about OpenStack Design Summits ?

Some people have been asking me if OpenStack should move to a similar model. My answer is definitely not.

When Rick Clark imported the UDS model from Ubuntu to OpenStack, it was to fulfill one of the 4 Opens we pledged: Open Design. In OpenStack Design Summits, we openly debate how features should be designed, and empower the developers in the room to make those design decisions. Point [2] above is therefore essential. In OpenStack we also have a lot of different development groups working in parallel, and making sure we don’t duplicate effort is key to limit friction and make the best use of our resources. So we can’t just pass on point [4]. With more than 200 different developers authoring changes every month, the OpenStack development community is way past Dunbar’s number. Thread after thread, some resentment can build up over time between opposed developers. Get them to informally talk in person over a coffee or a beer, and most issues will be settled. Point [5] therefore lets us keep a healthy developer community. And finally, with about 20k changes committed per year, OpenStack developers are pretty busy. Having a week to celebrate and recharge motivation batteries every 6 months doesn’t sound like a bad thing. So we’d like to keep point [1].

So for OpenStack it definitely makes sense to keep our Design Summits the way they are. Running them as a track within the OpenStack Summit allows us to fund them, since there is so much momentum around OpenStack and so many people interested in attending those. We need to keep improving the remote participation options to include developers that unfortunately cannot join us. We need to keep doing it in different locations over the world to foster local participation. But meeting in person every 6 months is an integral part of our success, and we’ll keep doing it.

Next stop is in Portland, from April 15 to April 18. Join us !

OpenStack at FOSDEM ’13

January 11, 2013 Leave a comment

In 3 weeks, free and open source software developers will converge to Brussels for 2+ days of talks, discussions and beer. FOSDEM is still the largest gathering for our community in Europe, and it will be a pleasure to meet again with longtime friends. Note that FOSDEM attendance is free as in beer, and requires no registration.

OpenStack will be present with a number of talks in the Cloud devroom in the Chavanne auditorium on Sunday, February 3rd:

There will also be OpenStack mentions in various other talks during the day: Martyn Taylor should demonstrate OpenStack Horizon in conjunction with Aeolus Image Factory at 13:30, and Vangelis Koukis will present Synnefo, which provides OpenStack APIs, at 14:00.

Finally, I’ll also be giving a talk, directed to Python developers, about the OpenStack job market sometimes Sunday in the Python devroom (room K.3.401): Get a Python job, work on OpenStack.

I hope you will join us in the hopefully-not-dead-frozen-this-time and beautiful Brussels !

What to expect from Grizzly-1 milestone

November 23, 2012 1 comment

The first milestone of the OpenStack Grizzly development cycle is just out. What should you expect from it ? What significant new features were added ?

The first milestones in our 6-month development cycles are traditionally not very featureful. That’s because we are just out of the previous release, and still working heavily on bugs (this milestone packs 399 bugfixes !). It’s been only one month since we had our Design Summit, so by the time we formalize its outcome into blueprints and roadmaps, we are just getting started with feature implementation. Nevertheless, it collects a lot of new features and bugfixes that landed in our master branches since mid-September, when we froze features in preparation for the Folsom release.

Keystone is arguably where the most significant changes landed, with a tech preview of the new API version (v3), with policy and RBAC access enabled. A new ActiveDirectory/LDAP identity backend was also introduced, while the auth_token middleware is now shipped with the Python Keystone client.

In addition to fixing 185 bugs, the Nova crew removed nova-volume code entirely (code was kept in Folsom for compatibility reasons, but was marked deprecated). Virtualization drivers no longer directly access the database, as a first step towards completely isolating compute nodes from the database. Snapshots are now supported on raw and LVM disks, in addition to qcow2. On the hypervisors side, the Hyper-V driver grew ConfigDrive v2 support, while the XenServer one can now use BitTorrent as an image delivery mechanism.

The Glance client is no longer copied within Glance server (you can still find it with the Python client library), and the Glance SimpleDB driver reaches feature parity with the SQLAlchemy based one. A number of cleanups were implemented in Cinder, including in volume drivers code layout and API versioning handling.  Support for XenAPI storage manager for NFS is back, while the API grew a call to list bootable volumes and a hosts extension to allow service status querying.

The Quantum crew was also quite busy. The Ryu plugin was updated and now features tunnel support. The preparatory work to add advanced services was landed, as well as support for highly-available RabbitMQ queues. Feature parity gap with nova-network was reduced by the introduction of a Security Groups API.

Horizon saw a lot of changes under the hood, including unified configuration. It now supports Nova flavor extra specs. As a first step towards providing cloud admins with more targeted information, a system info panel was added. Oslo (formerly known as openstack-common) also saw a number of improvements. The config module (cfg) was ported to argparse. Common service management code was pushed to the Oslo incubator, as well as a generic policy engine.

That’s only a fraction of what will appear in the final release of Grizzly, scheduled for April 2013. A lot of work was started in the last weeks but will only land in the next milestone. To get a glimpse of what’s coming up, you can follow the Grizzly release status page !

Why OpenStack doesn’t need a Linus Torvalds

October 25, 2012 3 comments

As comparing OpenStack with Linux becomes an increasingly popular exercise, it’s only natural that people and press articles start to ask where the Linus of OpenStack is, or who the Linus of OpenStack should be. This assumes that technical leaders could somehow be appointed in OpenStack. This assumes that the single dictator model is somehow reproducible or even desirable. And this assumes that the current technical leadership in OpenStack is somehow lacking. I think all those three assumptions are wrong.

Like Linux, OpenStack is an Open Innovation project: an independent, common technical playground that is not owned by a single company and where contributors form a meritocracy. Assuming you can somehow appoint leaders in such a setting shows a great ignorance of how those projects actually work. Leaders in an open innovation project don’t derive their authority from their title. They derive their authority from the respect that the other contributors have for them. If they lose this respect, their leadership will be disputed and you’ll face the risk of a fork. Project leaders are not appointed, they are grown. Linus wasn’t appointed, and he didn’t decide one day that he should lead Linux. He grew as the natural leader for this community over time.

Maybe people asking for a Linus of OpenStack like the idea of a single dictator sitting at the top. But that setup is not easily reproduced. Three conditions need to be met: you have to be the founder (or first developer) of the project, your project has to grow sufficiently slowly so that you can gather the undisputed respect of incoming new contributors, and you have to keep your hands deep in technical matters over time (to retain that respect). Linus checked all those boxes. In OpenStack, there were a number of developers involved in it from the start, and the project grew really fast, so a group of leaders emerged, rather than a single undisputed figure.

I’d also argue that the “single leader” model is not really desirable. OpenStack is not a single project, it’s a collection of projects. It’s difficult to find a respected expert in all areas, especially as we grew by including new projects within the OpenStack collection. In addition to that, Linux as a project still struggles with its bus factor of 1 and how it would survive Linus. Organizing your technical leadership in a way that makes it easier for leadership to transition to new figures makes a stronger and more durable community.

Finally, asking for a Linus of OpenStack is somehow implying that the current technical leadership is insufficient, which is at best ignorant, at worse insulting. Linus fills two roles within Linux: the technical lead role (final decision on technical matters, the buck stops here) and the release management role (coordinating the release development cycles and producing releases). OpenStack has project technical leads (“PTLs”) to fill the first role, and a (separate) release manager to fill the second. In addition to that, to solve cross-project issues, we have a Technical Committee (which happens to include the PTLs and release manager).

If you are under the impression that this multi-headed technical leadership might result in non-opiniated choices, think twice. The new governance model establishing the Technical Committee and the full authority of it over all technical matters in OpenStack is only a month old, previously the project (and its governance model) was still owned by a single company. The PTLs and Technical Committee members are highly independent and have the interests of the OpenStack project as their top priority. Most of them actually changed employers over the last year and continued to work on the project.

I think what the press and the pundits actually want is a more visible public figure, that would make stronger design choices, if possible with nice punch lines that would make good quotes. It’s true that the explosive growth of the project did not leave a lot of time so far for technical leaders of OpenStack to engage with the press. It’s true that the OpenStack leadership tends to use friendly words and prefer consensus where possible, which may not result in memorable quotes. But confusing that with weakness is really a mistake. Technical leadership in OpenStack is just fine the way it is, thank you for asking.

The value of Open Development

October 23, 2012 12 comments

Mark’s recent blogpost on Raring community skunkworks got me thinking. I agree it would be unfair to spin this story as Canonical/Ubuntu switching to closed development. I also agree that (as the damage control messaging was quick to point out) inviting some members of the community to participate in closed development projects is actually a step towards more openness rather than a step backwards.

That said, it certainly is making the “closed development” option more official and organized, which is not a step in the right direction in my opinion. It reinforces it as a perfectly valid option, while I would really like it to be an exception for corner cases. So at this point, it may be useful to insist a bit on the benefits of open development, and why dropping them might not be that good of an idea.

Open Development is a transparent way of developing software, where source code, bugs, patches, code reviews, design discussions, meetings happen in the open and are accessible by everyone. “Open Source” is a prerequisite of open development, but you can certainly do open source without doing open development: that’s what I call the Android model and what others call Open behind walls model. You can go further than open development by also doing “Open Design”: letting an open community of equals discuss and define the future features your project will implement, rather than restricting that privilege to a closed group of “core developers”.

Open Development allows you to “release early, release often” and get the testing, QA, feedback of (all) your users. This is actually a good thing, not a bad thing. That feedback will help you catch corner cases, consider issues that you didn’t predict, get outside patches. More importantly, Open Development helps lowering the barrier of entry for contributors to your project. It blurs the line between consumers and producers of the software (no more “us vs. them” mentality), resulting in a much more engaged community. Inviting select individuals to have early access to features before they are unveiled sounds more like a proprietary model beta testing program to me. It won’t give you the amount of direct feedback and variety of contributors that open development gives you. Is the trade-off worth it ?

How much as I dislike the Android model, I understand that the ability for Google to give some select OEMs a bit of advance has some value. Reading Mark’s post though, it seems that the main benefits for Ubuntu are in avoiding early exposure of immature code and get more splash PR effect at release time. I personally think that short-term, the drop in QA due to reduced feedback will offset those benefits, and long-term, the resulting drop in community engagement will also make this a bad trade-off.

In OpenStack, we founded the project on the Four Opens: Open Source, Open Development, Open Design and Open Community. This early decision is what made OpenStack so successful as a community, not the “cloud” hype. Open Development made us very friendly to new developers wanting to participate, and once they experienced Open Design (as exemplified in our Design Summits) they were sold and turned into advocates of our model and our project within their employing companies. Open Development was really instrumental to OpenStack growth and adoption.

In summary, I think Open Development is good because you end up producing better software with a larger and more engaged community of contributors, and if you want to drop that advantage, you better have a very good reason.

Grizzly Design Summit schedule posted

October 10, 2012 2 comments

Next week our community will gather in always-sunny San Diego for the OpenStack Summit. Our usual Design Summit is now a part of the general event: the Grizzly Design Summit sessions will run over the 4 days of the event ! We start Monday at 9am and finish Thursday at 5:40pm. The schedule is now up at:

This link will only show you the Design Summit sessions. Click here for the complete schedule. Minor scheduling changes may still happen over the next days as people realize they are double-booked, but otherwise it’s pretty final now.

For newcomers, please note that the Design Summit is different from classic conferences or the other tracks of the OpenStack Summit. There are no formal presentations or speakers. The sessions at the Design Summit are open discussions between contributors on a specific development topic for the upcoming development cycle, moderated by a session lead. It is possible to prepare a few slides to introduce the current status and kick-off the discussion, but these should never be formal speaker-to-audience presentations.

I’ll be running the Process topic, which covers the development process and core infrastructure discussions. It runs Wednesday afternoon and all Thursday, and we have a pretty awesome set of stuff to discuss. Hope to see you there!

If you want to talk about something that is not covered elsewhere in the Summit, please note that we’ll have an Unconference room, open from Tuesday to Thursday. You can grab a 40-min slot there to present anything related to OpenStack! In addition to that, we’ll also have 5-min Lightning talks after lunch on Monday-Wednesday… where you can talk about anything you want. There will be a board posted on the Summit floor, first come, first serve :)

More details about the Grizzly Design Summit can be found on the wiki. See you all soon!
