If the highest priorities include granular, dynamic, resource allocation for
multiple Solaris instances, then use CMT servers' Logical Domains.
■
If the maximum number of virtual instances with the most flexible resource
control is important within a single Solaris kernel environment, then use
Solaris Containers as the primary virtualization technology.
■
If you are using Dynamic Domains or Logical Domains, deploy applications in
Containers within each domain. This approach increases operational flexibil-
ity without adding cost, and it permits multiple Solaris virtual environments
to reside within a single domain. You can also use Containers to harden the
operating environment of the workload against intruders.
■
Consider using the x86 environment:
If different operating systems are used, or different Solaris kernel levels, use
virtual machines hosted by an x86 hypervisor such as Oracle VM VirtualBox,
Oracle VM Server for x86, xVM hypervisor, VMware, or Microsoft Windows
Server 2008 Hyper-V.
■
If the maximum number of virtual instances with the most flexible resource
control is important, use Containers as the primary virtualization technology.
■
If you are using virtual machines, deploy Solaris applications in Containers
within each guest. This approach provides operational flexibility without
adding cost, and it permits multiple Solaris VEs to reside within a single
domain.

Let's use the decision tree method described previously with some examples.
In your data center, you need to increase the workload density of high-scale,
mission-critical workloads (20 or more cores per workload). This situation has the
following specific needs:
Mission-critical workloads should be placed in the lowest-risk environments.
Consolidation adds risk, while isolation reduces it, with isolation being a
