Being a PI consultant developer for the last 13 years I found this very interesting. I didn't know OSISoft had a system running in Microsoft's datacenter. We're looking at putting a solution together for a customer with datacenters handling email from 19,000 businesses with 7 million end users. Energy usage is going to be one of the key metrics. PI is really proving its worth in many new fields now.
OSISoft are really consolidating their grip on EMEA territories now. It seems that they are really moving up a gear now. There are major releases of the PI Server software coming out very soon now too.
