If I spread a bunch of VM copies around who knows what kind of life they start leading. Some will get upgrades, some won't ..<br /> If I get an image from someone, how did he get there ? Nobody knows ..</p> <p>To me Image Sprawl is more than not being able to to manage your Virtual Machines, it also matters for physical machines that are being deployed using a golden image.</p> <p>Now rewind back about 4 something years.. back then I wrote a paper for LinuxKongress titled <a href="http://howto.krisbuytaert.be/AutomatingVirtualMachineDeployment/#AEN34" rel="nofollow">Automating Xen Virtual Machine Deployment</a> which described a Hybrid way of Bootstrapping an infrastructure.<br /> Quicly summarized, you use the benefits of images to quickly deploy a minimal image which<br /> <a href="http://madstop.com/2009/02/04/golden-image-or-foil-ball/" rel="nofollow">Luke</a> today calls a Stem Cell then go on using centralized package management and a configuration management tool to keep them up to par. There are 2 things that changed in between,<br /> we replaced CFEngine with Puppet , and the fact that today <a href="http://news.cnet.com/8301-13505_3-10157591-16.html?tag=mncol;title" rel="nofollow">some people</a> do care a bit more about the infrastructure side of the web, guess we have to thank Amazon and the Cloud Hype for that</p> <p>But fundamentally .. not that much changed :)</p> http://127.0.0.1:8080/blog/image-sprawl-and-new-cure#comments automating cfengine cloud devministration hype LinuxKongress open source opensource puppet systemimager toldyaso virtualization Thu, 05 Feb 2009 22:24:43 +0000 Kris Buytaert 871 at http://127.0.0.1:8080/blog http://127.0.0.1:8080/blog/node/721 <p><a href="http://blog.xen.org/index.php/2008/08/27/xen-summit-2009-proposal/" rel="nofollow">Stephen</a> , good thing you think about touring to Europe again for the Xen Summit.</p> <p>Colocating with <a href="http://www.linuxtag.org/" rel="nofollow">LinuxTag</a> or <a href="http://www.linux-kongress.org" rel="nofollow">LinuxKongress</a> would really be a good idea, but make<br /> sure to organize it the day before or after , not during the congress :)<br /> On the other hand .. you wrote LinuxKongress, but you probably meant Linuxconf.eu didn't you ?</p> <p>But then again Cambridge is also a lovely place for a summit ;)</p> http://127.0.0.1:8080/blog/node/721#comments LinuxKongress linuxtag xen xensummit Tue, 02 Sep 2008 18:52:01 +0000 Kris Buytaert 721 at http://127.0.0.1:8080/blog http://127.0.0.1:8080/blog/node/636 <p>Weird..
