Already virtualized "the hard stuff"

We use VMWare for small applications and infrastructure clutter.

- is easy for easy workloads

- is very expensive

- is not architected for heavy I/O

- cannot have a virtual machine larger than 8 threads

PowerVM

- easy but you need to use AIX versions of software

- makes Power systems cheap compared to x86+VMWare

- Can handle the highest transaction rates we have had on black Friday

- can scale from one thread to I heard over a thousand in the new boxes.

Its a matter of picking the right platforms for the right work vs. how to try to get VMWare to do something it was not made to do
