In just over a week, quite a large cross-section of the Ubuntu community and representatives from many free software projects and companies will gather in Orlando to map out the Precise Pangolin. Now’s the time to prepare for the event, with 11.10 out (well done everybody!) and the key infrastructure slotting into place.
Figuring out the optimal balance of goals is the work of the summit, but we can lay out some over-arching themes that have been in progress during this meta-cycle and come to their full fruition in the LTS release. We can also remind ourselves of the ways in which an LTS is different, and the impact that will have on our choices in Orlando.
Being an LTS
As Dustin pointed out, this is the fourth Ubuntu LTS release, and as such it needs to carry on, and entrench, the reputation of the LTS as a carrier-grade platform for mission-critical server deployments and large scale desktop deployments. That means:
- Adjusting the cycle to allocate more time for resolving issues
- Introducing minimal new infrastructure or platform-visible change
- Goal-driven and continuously benchmarked programs of action around performance
- First-class accessibility for those with special interaction needs
- Enablement and certification of the sorts of hardware people will deploy at scale and in the datacenter
Carrier-grade Cloud Infrastructure and Guest
Ubuntu is the #1 OS for cloud computing, whether you measure it by the number of instances running on all the major public clouds, the number of Ubuntu-based cloud appliances, the number of public and private clouds running on Ubuntu host OS. The extraordinary diversity of the Ubuntu community, the calibre of collaboration between Ubuntu and OpenStack, and the focused efforts of Canonical to make Ubuntu useful in the cloud have all contributed to that position. In 12.04 LTS we must deliver:
- world’s best cloud infrastructure powered by OpenStack’s corresponding major release
- perfect support for cloud-oriented hardware from Canonical’s partner IHV’s
- a great hybrid-cloud story, for those using a mixture of private and public clouds
- world’s best guest OS on AWS, Rackspace and other public cloud infrastructures
Pangolin-worthy Server Release
We have a proud heritage from Debian which 12.04 LTS needs to celebrate and maintain; although we have some key advantages for enterprises deploying Ubuntu over Debian in our ability to enable some additional security features in the Linux kernel and toolchain, as well as support, certification and assurance, the lean-mean-green-machine nature of the Ubuntu Server experience owes much to Debian’s focus on quality and precision.
12.04 will be the first LTS to support the ARM architecture on selected ARM SoC parts. In a world where computational density is increasingly prioritized over single-thread performance, the entry of ARM to the server market is a very interesting shift. Ubuntu has established a very strong competence in ARM and I think the 12.04 LTS release will power a new generation of power-focused hardware for the data centre.
The nail-biting transitions to Unity and Gnome 3 are behind us, so this cycle is an opportunity to put perfection front and center. We have a gorgeous typeface that was designed for readability, which is now available in Light and Medium as well as Regular and Bold, and has a Mono variant as well. That’s an opportunity to work through the whole desktop interface and make sure we’re using exactly the right weight in each place, bringing the work we’ve been doing for several cycles fully into focus.
We also need to do justice to the fact that 12.04 LTS will be the preferred desktop for many of the world’s biggest Linux desktop deployments, in some cases exceeding half a million desktops in a single institution. So 12.04 is also an opportunity to ensure that our desktop is manageable at scale, that it can be locked down in the ways institutions need, and that it can be upgraded from 10.04 LTS smoothly as promised. Support for multiple monitors will improve, since that’s a common workplace requirement.
During UDS we’ll build out the list of areas for refinement, polish and ‘precisioneering’, but the theme for all of this work is one of continuous improvement; no new major infrastructure, no work on pieces which are not design-complete at the conclusion of the summit.
While there are some remaining areas we’d like to tweak the user experience, they will probably be put on hold so we can focus on polish, performance and predictability. I’d like to improve the user experience around Workspaces for power users, and we’ll publish our design work for that, but I think it would be wisest for us to defer that unless we get an early and effective contribution of that code.
It’s going to be a blast in Orlando, as UDS always manages to bring together a fantastic crowd. And it’s going to be a beautiful, memorable release of Ubuntu in April 2012!
