And now for something completely different


And now for something completely different: IBM rolls the ‘four-hour’ out the door!

In the beginning, you paid based on the size of the machine.  Then came sub-capacity pricing, where you paid for what you used.  Seemed reasonable except it was (is) based on extremely complex metrics and methods using a ‘rolling four-hour average’ of consumption.

That has basically been the way of things since 2002.

On May 14th, IBM announced ‘Tailored Fit Pricing’.  This new model throws the R4HA/4HRA out the window.  No longer do you need to worry about peak hours or even days.  Your total MSU (CPU) consumption for the year, will determine your bill.

Seems simple enough right?  Let’s take a closer look.
