#11 – Ubuntu is the #1 platform for production OpenStack deployments

Mark Shuttleworth - Wed, 05/03/2014 - 08:36

OpenStack has emerged as the consensus forum for open source private cloud software. That of course makes it a big and complex community, with complex governance and arguably even more complex politics, but it has survived several rounds of competition and is now settling down as THE place to get diverse vendors to work together on a IAAS that anybody can deploy for themselves. It is a big enough forum with sufficient independent leadership that no one vendor will ever control it (despite some fantastically impressive efforts to do so!). In short, OpenStack is what you want if you are trying to figure out how to build yourself a cloud.

And by quite a large majority, most of the people who have actually chosen to deploy OpenStack in production, have done so on Ubuntu.

At the latest OpenStack summit, an official survey of production OpenStack deployments found 55% of them on Ubuntu, a stark contrast with the 10% of OpenStack deployments on RHEL.

Canonical and Ubuntu play an interesting role in OpenStack. We do not seek to control any particular part of the project, although some of our competitors clearly think that would be useful for them to achieve, we think OpenStack would be greatly diminished in importance if it was perceived to be controlled by a single vendor, and we think there are enough contributors and experts around the table to ensure that the end result cannot actually be controlled by a single party. To a certain extent, the battle for notional control of key aspects of OpenStack just holds the project back; it’s a distraction from the real task at hand, which is to deliver a high quality, high performance open cloud story. So our focus is on supporting the development of OpenStack, supporting the broadest range of vendors who want to offer OpenStack solutions, components and services, and enabling a large ecosystem to accelerate the adoption of OpenStack in their markets.

It’s a point of pride for us that you can get an OpenStack cloud built on Ubuntu from just about every participant in the OpenStack ecosystem – Dell, HP, Mirantis, and many more – we think the healthiest approach is for us to ensure that people have great choices when it comes to their cloud solution.

We were founding members and are platinum sponsors of the OpenStack Foundation. But what’s more important to us, is that most OpenStack development happens on Ubuntu. We take the needs of OpenStack developers very seriously – for 14.04 LTS, our upcoming bi-annual enterprise release, a significant part of our product requirements were driven by the goal of supporting large-scale enterprise deployments of OpenStack with high availability as a baseline. Our partners like HP, who run one of the largest OpenStack public cloud offerings, invest heavily in OpenStack’s CI and test capabilities, ensuring that OpenStack on Ubuntu is of high quality for anybody who chooses the same base platform.

We publish stable, maintained archives of each OpenStack release for the LTS releases of Ubuntu. That means you can ALWAYS deploy the latest version of OpenStack on the current LTS of Ubuntu, and there is a clear upgrade path as new versions of both OpenStack and Ubuntu are released. And the fact that the OpenStack release cadence and the Ubuntu release cadence are perfectly aligned is no accident – it ensures that the OpenStack developers can always deliver their latest code straight to a very large audience of developers and operators. That’s important because of the extraordinary pace of innovation inside OpenStack; there are significant and valuable improvements in each six-month release, so customers, even enterprise customers, find themselves wanting a more aggressive upgrade schedule for OpenStack than is normal for them in platform environments. We support that and have committed to continue doing so, though we do expect the urgency of those upgrades to diminish as OpenStack matures over the next three years.

For commercial support of OpenStack, we are happy for industry to engage either with our partners who can provide local talent combined with an escalation path to Canonical for L3 support of the whole solution, or directly with Canonical if the circumstances warrant it. That means building on Ubuntu opens up a wide range of solution providers who can make the same high commitment to SLAs and upgrades.

For Canonical itself, our focus is on scale and quality. Our direct customers run the very largest production deployments of OpenStack, both private and public, and we enjoy collaborating with their architects to push the limits of the stack as it stands today. That gives us a lot of insight into the approaches being taken by a wide range of architects in telco, finance and media. We ourselves invest very heavily in testing, continuous integration, and interoperability, with the largest OpenStack interop program (OIL) that gives us the ability to speak with confidence about what combinations of vendor offerings will actually work, and in many cases, how they will perform together for different applications.

The fact that the traditional enterprise Linux vendors have now joined OpenStack is a tremendous validation of the role that OpenStack has assumed in industry: THE open cloud forum. But for all the reasons outlined above, most of the actual production deployments of OpenStack are not on traditional, legacy enterprise Linux. This mirrors the public cloud, where even the largest and most mission-critical deployments tend not to be on proprietary Linux offerings; the economics of HA single-node solutions just don’t apply in a scale-out environment. So just as Ubuntu is by far the most widely used platform for public cloud guests, it is also on track to be the enterprise choice for scale-out infrastructure like IAAS, storage, and big data. Even if you have always done Linux a particular way, the transition to scale-out thinking is an opportunity to reset expectations about your base OS; and for the fastest-moving players in telco, media and finance, Ubuntu turns out to be a great way to get more done, more efficiently.

#12 – Ubuntu is the majority of public cloud workloads

Mark Shuttleworth - Wed, 19/02/2014 - 10:35

In a series of 12 posts, I’ll make the case for Ubuntu as the platform of choice for public clouds, enterprise clouds and related scale-out initiatives.

Cloud computing is largely being defined on public clouds today. There are a range of initiatives for private cloud computing – some proprietary, some open – but for sheer scale and traction, the game today is all about public cloud services. Azure, AWS, a range of offerings from telco’s and service providers together with innovative takes on the concept from hardware OEMs have been the leading edge of the cloud market for the past five years. We do expect private clouds to flourish around OpenStack, but we expect the gene pool of innovation to stay on the public clouds for some time.

And what do people run on public clouds? By substantial majority, most of that innovation, most of that practical experience and most of the insights being generated are on Ubuntu.

Digital Ocean, the fastest growing new challenger in the US public cloud market, published definitive statistics on the share of operating systems that customers choose on their cloud:

Ubuntu is the most popular OS on public clouds, by far.

AWS hasn’t spoken publicly on the topic but there are a number of measurements by third parties that provide some insight. For example,  SCALR offer a management service that is used by enterprises looking for more institutional management control of the way their teams use Amazon. One might think that an enterprise management perspective would be skewed away from Ubuntu towards traditional, legacy enterprise Linux, but in fact they find that Ubuntu is more than 70% of all the images they see, three times as popular as CentOS.

There is no true safety in numbers, but there is certainly reassurance. Using a platform that is being used by most other people means that the majority of the content you find about how to get things done efficiently is immediately relevant to you. Version skew – subtle differences in the versions of components that are available by default on your platform of choice – is much less of an issue if the guidebook you are reading assumes you’re on the same platform they used.

There is also the question of talent – finding people to get amazing things done on the cloud is a lot easier if you let them use the platforms they have already grown comfortable with. They can be more productive, and there are many more of them around to hire. Talking to companies about cloud computing today it’s clear their biggest constraint is knowledge acquisition; the time it takes to grow own internal skills or to hire in the necessary skills to get the job done. Building on Ubuntu gives you a much broader talent and knowledge base to work with. Training your own team to use Ubuntu if they are familiar with another Linux is a relatively minor switch compared to the fundamental challenge of adopting a IAAS-based architecture. Switching to Ubuntu is the fastest way to tame that dragon, and the economics are great, too.

That’s why we see many companies that have been doing Linux one way for a decade switching to Ubuntu when they switch to the cloud. Even if what they are doing on the cloud is essentially the same as something they already do on another platform, it’s “easier with Ubuntu on the cloud”, so they switch.

Losing graciously

Mark Shuttleworth - Fri, 14/02/2014 - 14:01

With Bdale Garbee’s casting vote this week, the Debian technical committee finally settled the question of init for both Debian and Ubuntu in favour of systemd.

I’d like to thank the committee for their thoughtful debate under pressure in the fishbowl; it set a high bar for analysis and experience-driven decision making since most members of the committee clearly took time to familiarise themselves with both options. I know the many people who work on Upstart appreciated the high praise for its code quality, rigorous testing and clarity of purpose expressed even by members who voted against it; from my perspective, it has been a pleasure to support the efforts of people who want to create truly great free software, and do it properly. Upstart has served Ubuntu extremely well – it gave us a great competitive advantage at a time when things became very dynamic in the kernel, it’s been very stable (it is after all the init used in both Ubuntu and RHEL 6 and has set a high standard for Canonical-lead software quality of which I am proud.

Nevertheless, the decision is for systemd, and given that Ubuntu is quite centrally a member of the Debian family, that’s a decision we support. I will ask members of the Ubuntu community to help to implement this decision efficiently, bringing systemd into both Debian and Ubuntu safely and expeditiously. It will no doubt take time to achieve the stability and coverage that we enjoy today and in 14.04 LTS with Upstart, but I will ask the Ubuntu tech board (many of whom do not work for Canonical) to review the position and map out appropriate transition plans. We’ll certainly complete work to make the new logind work without systemd as pid 1. I expect they will want to bring systemd into Ubuntu as an option for developers as soon as it is reliably available in Debian, and as our default as soon as it offers a credible quality of service to match the existing init.

Technologies of choice evolve, and our platform evolves both to lead  (today our focus is on the cloud and on mobile, and we are quite clearly leading GNU/Linux on both fronts) and to embrace change imposed elsewhere. Init is contentious because it is required for both developers and system administrators to understand its quirks and capabilities. No wonder this was a difficult debate, the consequences for hundreds of thousands of people are very high. From my perspective the fact that good people were clearly split suggests that either option would work perfectly well. I trust the new stewards of pid 1 will take that responsibility as seriously as the Upstart team has done, and be as pleasant to work with. And… onward.

All Star ‘Buntu

Mark Shuttleworth - Wed, 12/02/2014 - 07:32

As prep for the upcoming 14.04 LTS release of Ubuntu I spent some quality time with each of the main flavours that I track – Kubuntu, Ubuntu GNOME, Xubuntu, and Ubuntu with the default DE, Unity.

They are all in really great shape! Thanks and congratulations to the teams that are racing to deliver Trusty versions of their favourite DE’s. I get the impression that all the major environments are settling down from periods of rapid change and stress, and the timing for an LTS release in 14.04 is perfect. Lucky us

The experience reminded me of something people say about Ubuntu all the time – that it’s a place where great people bring diverse but equally important interests together, and a place where people create options for others of which they are proud. You want options? This is the place to get them. You want to collaborate with amazing people? This is the place to find them. I’m very grateful to the people who create those options – for all of them it’s as much a labour of love as a professional concern, and their attention to detail is what makes the whole thing sing.

Of course, my testing was relatively lightweight. I saw tons of major improvements in shared apps like LibreOffice and Firefox and Chromium, and each of the desktop environments feels true to its values, diverse as those are. What I bet those teams would appreciate is all of you taking 14.04 for a spin yourselves. It’s stable enough for any of us who use Linux heavily as an engineering environment, and of course you can use a live boot image off USB if you just want to test drive the future. Cloud images are also available for server testing on all the major clouds.

Having the whole team, and broader community, focus on processes that support faster development at higher quality has really paid off. I’ve upgraded all my systems to Trusty and those I support from afar, too, without any issues. While that’s mere anecdata, the team has far more real data to support a rigorous assessment of 14.04′s quality than any other open platform on the planet, and it’s that rigour that we can all celebrate as the release date approached. There’s still time for tweaks and polish; if you are going to be counting on Trusty, give it a spin and let’s make sure it’s perfect.
