Since the first Linux Expo back in 1999, the event has changed, first growing a lot, and it is now going back to a smaller size, however, keeping what makes it very attractive, a combination of enterprise boths, community boths and free conferences which are a big success every year.
I passed most of my time of Tuesday having very interesting discussions and news from the french community, discovering the new e-Novance big OpenStack player (thanks Erwan), talking FLOSS history with Denis Bodor on the Linux Mag both, talking with friends at Combodo (TeamIP and their great iTOP FLOSS CMDB) or at normation (Rudder and CFengine), and getting the latest news from FusionDirectory, FusionInventory, AFUL or APRIL members, and other multiple communities.
I didn’t see time passed ! But I had to jump in the RER to attend, for once I could, the reheasal of the Mozart Requiem in Etampes directed by Jean Belliard ! You should attend their concert the 15th of June there. That was multiple great pleasures: First to sing this master piece under the direction of Jean, something I have not been able to do during the 12 years I sung at the choir (I also miss the mass from Bach !). And also because I could join my daughter and sing also with her in the choir, and that’s something I wish to everybody😉 Of course, lots of discussions at then end of the rehearsal again, shoretened alas to be able to go back to Paris and attend the second day of Solutions Linux.
I first participated to a round table on Open Source Governance with Véronique Torner (she has a great knowledge of the FLOSS governance world and her comments were remarkable), Gaël Blondelle who also has a very interesting knowledge of industrial use cases of FLOSS, and of the Eclipse Foundation, Benjamin Jean, who is the legal person I prefer to work with, as he can really make you love legal and lawyers !, even when you’re a developer, and he has numerous examples very interesting to share, so I recommend listening to him. The round table was lead by Patrice Bertrand in front of some 40 people in the room, which is great for a hard topic like Open Source Governance.
Of course, it’s always too short, but I hope we showed how useful it is to control Open Source usage in enterprise, as well as SMBs, and that the goal is to expand usage, and get the most out of it, instead of creating FUD.
And after that, a sandwish and it ws time to lead the Sysadmin track with my colleague François Jeanmougin.
We had initially planned to have 4 hours, and thus gave 30 minutes to each of our 6 speakers, plus 1 hour for a round table. However, later on, we were restricted to 3 hours only. That’s an issue as this track used to have a full day some years ago. I decided that I didn’t want to cancel any speaker as their talks were indeed very valuable in our context of Data Center automation with/using FLOSS. And each speaker accepted to reduce their talk to 20′, which is really short, but forced them somewhere to go straight to their point and we thus had a dense but highly interesting track ! And extremely well followed as you can see below:
We started with Jonathan Clarke from Normation who did a global overview of what needs to be done to automate complex IT environement with FLOSS solutions. As he didn’t had eough time to develop the project he’s contributing to (Rudder) I really encourage you to take time to read more on it.
Next speaker was logically Erwan Talloc from Combodo to present how we can today by combining multiple FLOSS tools, provide to enterprises an ITIL compliant FLOSS solution stack. Of course their iTop product is at the center, relevant of course for a CMDB. This stack is currently developped for answering a customer need, and hopefully, we’ll be able next year to present a concrete use case of this during the track.
And when we speak of central management of systems, Directory is near to your mind, as well as to Benoit Mortier’s one (from Opensides), who thinks natively LDAP ! He presented FusionDirectory, complementary to all what was shown before, allowing to manage through OpenLDAP, using a very nice Web based interface servers, PCs, IP phones, or fax, as well as users, sysem deployment and much more.
Going deeper in system management, I was really waiting the next speaker Frédéric Crozat from SUSE and his systemd subject. Too bad he had some issues with his laptop (btrfs related, not systemd related even if who knows ;-)) and could only make a short presentation. Systemd is supposed to colsve all the badness of sysVinit, speed, deps, … As I really hate systemd at the moment, for the multiple problems it created for me in my system managements, with in short, problems with chroots, problems with no X started when another unrelated issue happen, problem with memory consumption (44 MB for an init replacement and they say it’s not bloated !), problem with debugging requiring too many commands to pass to understand what is wrong, … I would have liked to ask many questions. For sure next time. Frédéric made his best to defend systemd but why are distros adopting it too early is something I have issue understandig. Sometimes I like the Debian approach !!
Always low in system management, we then had a talk on redundancy with load balancers and for load balancers, from Sébastien Rohaut (GFI) who covered of course ipvsadm and LVS, but also the various tools added around to make it always available, including his own makealive, giving users the possibility to avoid paying tons of euros for dedicated hardware platforms when this software soltion fits probably 80% of the needs.
Finally, Jean Gabès came on stage to explain to us what was new in Shinken. After many years of Nagios related confs, we had Jean for the first time 2 years ago. AsI found his solution interesting, I wanted to have him again presenting the evolution of monitoring and the constraints brought by a cloud context to that area.
Finally we made a 30′ question and answer session with the attendees, some speakers ( Jonathan Clarke, Erwan Talloc) and additional ones (Christophe Sautier (Objectif Libre), Guillaume Leccese (Oxalyde), Laurent Pinsivy (Méréthis)) and we had a great deal of questions, especially around the positioning of Data Center automation with regards to the cloud approach and some user experience feedback. Hopefully the audience was well informed and this session overall will contribute to increase FLOSS usage in data center even more.
So next year, hopefully, we’ll have more time (4 hours at least), more space (a 120 people room) but still the same energy and competence from speakers to have an always interesting track.
