"How do I know if I can virtualize my application using Sun Virtualization?"

Somebody asked me the other day, "How do I know when to use which Sun Virtualization Technology and how do I know if I can virtualize my application?" Well it depends on what problem your are trying to solve. The following are a some general rules of thumb that I use and I though I would share them with you.

Bare Metal Machine Running Solaris

\* Any Sparc Apps on Sparc Systems
\* Any X86 Apps on X86/X64 Systems

Solaris Containers (Zones)

\* Any Sparc Apps on Sparc Systems w/kernel restrictions
\* Any X86 Apps on X86/X64 w/kernel restrictions
\* There is only a single Solaris Kernel
\* Apps Restricted to user land type Apps
\* No Apps that need to talk directly to kernel or devices
\* Operating System Solaris 10
\* Sparc Branded Zones - Solaris 8, Solaris 9
\* X86 Branded Zones - Linux
\* Solaris 10 Containers can be run any where Solaris 10 is installed regardless (Bare Metal/LDoms/xVM Server)

xVM Logical Domains (LDoms)

\* Any Sparc Apps on T1 & T2 Systems
\* Solaris Operating System
\* There can be multiple Solaris Kernels (each thread can be a kernel)
\* Enterprise Grade Level Virtualization (RAS)
\* Type I Hypervisor Virtualization

xVM Server X86

\* Any X86 Apps on X86/X64
\* Multiple Operating Systems (Solaris X86, Windows & Linux)
\* Enterprise Grade Level Virtualization (RAS)
\* Type I Hypervisor Virtualization

xVM Virtual Box

\* Any X86 Apps on X86/X64
\* Multiple Operating Systems (Solaris X86, Windows & Linux)
\* Desktop/Laptop Grade Level virtualization for Software Development
\* Type II Hypervisor Virtualization
