A lot of questions in the annual user survey concern cloud computing. I administer some small businesses and use Ubuntu in most of them. Maybe my biggest client will one day use a personal cloud, and I applaud the efforts, but I can 't help but notice that other things are left in the cold. The survey wants to know how Ubuntu Server is used. I'm curious about the results and really wonder how many Ubuntu clouds there really are, in contrast to file, web, terminal and other servers.
I'd like to give an example of how we are using Ubuntu in one company and where it could be put to use in the future, along with the issues encountered. The reason for this is that I think there is a lot of room for improvement outside the cloud. We're a prepress company with a mixed network. - 3 Solaris Servers with Helios. Why not Ubuntu? - ZFS (does not need much explanation) - Helios, A commercial application to provide file and print sharing for Macintosh. - [bug 462169] "nmbd dies on startup when network interfaces are not up yet" These run Samba and are NFS servers. These machines are an example of what stability should be. No serious bugs. - 3 Ubuntu Virtual Hosts These run Karmic. They are basic installs with ubuntu-virt-server installed. They do suffer from some problems. - [bug 460914] "root device is sometimes not found" - [bug 446031] "static network interfaces do not come up at boot" - [bug 470776] "NFS shares do not mount at boot" - [bug 491273] "netfs storage pools are not autostarted" - [bug 444563] "udev errors all over the place" Aside from that, IF they want to find the root drive, are set to DHCP, and libvirt-bin is restarted, we can run virtual machines. kvm runs well, but I'm scared of reboots. When Karmic was just released, we used separate /boot on all servers which also rendered them unbootable. [bug 462961, fixed] Due to the above problems, I would love to have some sort of boot log [bug 328881] - 4 Ubuntu Virtual machines. These run Jaunty because of the above bugs and because of a regression [bug 224138] "No NFS modules in karmic 32-bit" 2 of these machines run our most important commercial production software. kubuntu-desktop is installed on them and the users use XMDCP to work on these servers. Users also run rdesktop from here to get to Microsoft Word on a MS Windows Terminal server. They do suffer from some problems. (I'm not mentioning Kubuntu stuff. It's not that bad) - [bug 366728] "LD_LIBRARY_PATH not loads from .profile" - [bug 374907] "libmotif3 crashes" - [bug 251709] "Caps Lock does not work in rdesktop" - [bug 86021 or 234543] "XDMCP does not work without reverse dns, or with the basic /etc/hosts" - 1 Debian based commercial router/firewall/mailserver Ubuntu could do this, but we're pretty happy with this machine. - There are also a lot of Windows Servers, virtual and physical. These will probably never be replaced. - The clients run Kubuntu, Windows and Mac OS 9/X. The Kubuntu machines are XDMCP server and normal workstations. Sometimes you hear: "it's open source. Don't complain and fix it yourself." That's partly true. I'm not a programmer, but I was able to patch libmotif3 to solve the crashes. The kind people in ubuntu-bugs also managed to convince me that I could package the new version of openmotif myself and put it in Debian. Maybe I'll learn how to do that, so that bug can at least be closed. I can understand that there is not a lot of interest in this package, but we need it and will probably need it for some time to come. What I can't understand is that there would be no interest in NFS. Is everyone using samba between unix machines these days? This is a real-life scenario. Is it common? I don't know. It's not free of struggles as you can see. So, this is a plea for quality. Cloud Computing might be very important, but please don't lose sight of the little guys who just want some 'classic' servers.
