One of the really exciting features that was introduced in Oracle Solaris 11.2 is called Unified Archives. Unified Archives provide system cloning and disaster recovery capabilities for the platform. Built on the foundations of Oracle Solaris ZFS, an archive can quickly be taken on a live running system thanks to snapshot and cloning. A single archive can be created for a complete system that includes a number of virtual environments. Once captured, it can be deployed using Automated Installer or using the existing zonecfg(1M) and zoneadm(1M) utilities during Oracle Solaris Zone creation. Thanks to integration with the IPS packaging system, an archive can be partially deployed with complete flexibility - across different systems of the same architecture, or using physical-to-virtual or virtual-to-physical transforms. They're completely flexible. Jesse Butler, the architect for Unified Archives, has already covered a lot of the basics in two blog posts: Introducing Unified Archives in Oracle Solaris 11.2 and Cloning Zones with Unified Archives.
Unified Archives are a pretty critical piece of the overall application lifecycle. Combined with Oracle Solaris Zones, Immutable Zones (read-only VMs), and our new compliance framework, we have a very nice set of technologies that can be combined to really aid developers and administrators in creating and deploying compliant application environments, from development through to test and eventually production. I've written an article that helps explain how you can achieve this, and greatly cut down the cost of ensuring certified and compliant applications and reducing the cost of human error or security exploits.
