I've looked at the amazon and google chargeback models. One of their
options is a fixed price until some number of CPU hours is exceeded.
This allows the 'easy' fixed fee, but also controls the resource
abuser. You would have to have tools in place to alert the abuser that
they have gone beyond their allotted resource consumption.

Hello!
There are going to be a lot of ideas on how to do charging all the way from
"we don't charge back" to "we charge by the micro-process".
Fixed-price charging is good for very well contained zLinux servers. Using
SHARE ABSOLUTE and even CPU POOLING can help with this. CPU POOLING is
really good if you are thinking of mixing those fixed-resource servers with
high-performance or "premium services" servers. There are pros and cons to
fixed price charging. A pro is it is MUCH easier than any other kind of
charging (other than no-cost!). A con is that some folks may think they
are being charged too much if they really don't use it that much or that
heavy, and some may not be thrilled being capped when they want to run
something heavy for a short while.
We use a variable rate based on consumption for most of our servers. We
also have "lab" servers that are contained within SHARE ABS. We have
processes to "cap" non-premium production servers when they get out of hand
and the entire processor has been running in the high 90's for CPU. We use
zVPS to collect all the data for the processor/LPARs and the zLinux servers
to evaluate what they are up to every minute. Using that data, we are able
to charge-back to the business units based on what they consume by
process/application. There is a small base charge for just having a server,
then the use of resources adds to it. This was all built over the last 10
years and we are still tuning it!
Figuring out what your business will accept for charging is the hard part.
Between the knobs in z/VM and performance monitoring/collecting tools
available, you can make it work the way you need it.

This seems to be the biggest hinder for most people to start using Linux
on z.
Anyone having done this ?
There is a number of options to limit cpu and resources, SHARE and setting
max memory for example. Is this helping out here ?
