Here's a pretty good comparison of Solaris Zones vs everything else: http://www.softpanorama.org/Solaris/Virtualization/zones.shtml
Zones are the best IMO because some of the key advantages that zones have: (1) You can snapshot and clone them and rewind to old snapshots if your zones have their own ZFS file systems. (2) You can cap what percentage of the CPU the zone is allowed to use or how much RAM it can use. There's lots of other fine grained resource controls in zones but I won't go into too much detail here. (3) Zones have better security. The zones processes are isolated in the kernel so that they can't interact with other processes outside of the zone. (4) VERY lightweight for virtualization (a typical idling zone on one of my servers where I'm logged in to that zone through SSH and typing in commands into BASH uses about 25 megabytes of RAM and 0.00% of the CPU. Try beating that with VMware. (5) You can move zones from one Solaris server to another pretty easily. (6) Soon Project Crossbow will be fully integrated and you'll have a 10 gigabit ethernet connection in between your zones. (7) There's a lot more advantages (way too many to list here, as there are thousand page manuals written on the subject) but I'm going to stop here and leave with just those few ideas to think about. -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
