Responding to a user who asked, "We are running/migrating to T2/T3/T4 servers, and considering for our setup the virtualization possibilities. What shall we go for, zones or ldoms? Karoly Vegh writes, "Zones and LDOMs are not rivalling, but complementary technologies. If you need kernelspace separation, use ldoms. But run your applications in zones within those ldoms anyway!" The question shouldn't be about zones vs. ldoms, Vegh continues. Use zones. Especially with Solaris 11, with Crossbow, the new network virtualization technology (that enables all your NGZs to have a dedicated IP stack) and the possibility to run Solaris 11 native zones and Solaris10 branded zones on top of Solaris 11, you have two quite powerful technologies to really get your server's worth - and by that I mean having a high server utilization. The higher that utilization is, the more you get for your costs.
