In the last post I discussed that the Golden Image approach still has its advantages even if you use configuration management frameworks like Puppet. But the success and the quality of this approach depends heavily on the available tools. Solaris 11.2 ships with the new “Unified Archives” technology, which was newly developed from scratch. Therefore it should be a much better solution compared to “Flash Archives” from Solaris 10. I assume it was easier to build a better tool on Solaris 11, because base technologies like IPS, ZFS and SMF could be fully leveraged.
A nice introduction of “Unified Archives” (“UAs”) can be found on the Oracle blog of Jesse Butler.
With AI (Automated Installer) Solaris 11 already has an install service with many great features. But if you don’t use AI very often, it can easily look complex. In this post I will show, how to deploy global zones with a simpler method.
