The big UDS-O
Last week in Budapest, Hungary the Ubuntu community had our semi-annual Ubuntu Developer summit. I was there along with both sponsored Ubuntu developers, upstreams, and canonical employees participating mostly in the Server and Cloud Tracks. Here are some of the sessions that were highlights for me during the week.
- Openstack At UDS, Ubuntu Cloud was announced which is run by Openstack. Everyone has assumed that this means that UEC and Eucalyptus is going away, which is not the case in Oneiric. Both Eucalyptus and Openstack will be in “main” and both will be supported in Oneiric. One way to think of this is that we both have MySQL and Postgresql in “main” because people still want to have a choice in which database you want to use. Providing both allows users to have an easier time to deploy either MySQL or Postgresql. Users are free to use either MySQL or Postgresql, which is really the essence of FOSS. Similarly, Ubuntu users for Oneiric will have either Eucalytpus or Openstack as a choice to deploy their private cloud. The session that we had Openstack mostly resolved about what integration points that we need to do for Oneiric and how we are going to do them.
- Orchestra was a big topic at UDS. Orchestra is an all in one provisioning server to deploy Ubuntu Server. Orchestra has several moving parts which includes cobbler, puppet, mcollective, nagios, cloud-init, and ensemble. The idea behind Orchestra is that given any N number of servers running bare-metal, easily deploy Ubuntu Server on it. This is a big change since the only way you could get Ubuntu Server was through the ISO and it was designed for a single server mind. With Orchestra, we are taking the best of opensource and making it easier to deploy Ubuntu Server for large scale deployments. Most of the sessions that I attended were either directly or indirectly apart of Orchestra.
- Ubuntu Server on Arm A long time ago when I was first starting out in the computer industry. I had access to a small little server called the netwinder. It was a StrongARM desktop server that runs quietly on a desk or as a 1U. The Netwinder was basically my first exposure to the ARM architecture and it was pretty cool, however it was way ahead of its time and died when Corel got out of the Linux business and Rebel.com died. Jump to, well, now, and there is a demand for servers with low power consumption and ARM is well suited in my opinion. Ubuntu Server is getting on the ground floor and I quite envious of the Ubuntu Arm team of the work they are doing in this area.
- Ubuntu as a host or what is old is new again Along with sessions about LXC and KVM we had a session about discussing Xen. Xen in the past has not been really supported by the Ubuntu Server Team or the Ubuntu Kernel Team due to the Xen patchset not included in the mainline kernel. Since the dom0 support has been included in the mainline kernel, distros such as Ubuntu can now support it properly. We had a good discussion about Xen and what needs to be done in order for Ubuntu to be a good host for Xen. I see us carrying the Xen 4.1 hypervisor and userland tools and associated bits that is needed to make Xen work really well on Ubuntu. It was great to have Ian Jackson an upstream xen.org developer from Citrix to answer questions for us as well.
- Server SRU process review Surprisingly, this was a well attended session as well on the last day. Most of our users on Ubuntu Server use the LTS releases and they want to have a stable server. In order to support those users we usually try to cherrypick fixes from the development release and backport them to the LTS releases and believe me we do care about our LTS uses. However, this takes time and we have a long list of things that we want to fix but just have not gotten around to it yet. A couple of ideas was risen from this session include using the backports, SRU process, and PPAs. However, the idea brought up of having a dedicated SRU person on the Ubuntu server who would rotate on a fixed time period was especially interesting because it would make sense for us since we would model it on how to the security team would do it.
It was nice to see everyone again and I’m looking forward to the next six months but there is a lot of work to be done. So okay go!
