Live / DR failover, assumes shared storage, mutual SAN, or some sort of replication. Storage to oneside, zones will allow you to move the application, as would RSF / SunCluster clustering software. So, clustering would cater for your needs too.
Centralised storage might be a bigger problem, as the live and dr systems will be in different physical locations ? Different IP addresses ??
Containers / zones - containers has some sort of resource control i.e. number of cpus / memory, zones are like containers but a more fluid set of resource controls.
Im currently do the same thing as you, looking at creating a DR of my live server, using zones / RSF.
