Why You Need a Trusted Advisor

I’ve providing advisory services to a Fortune 500 organization for a few months now. As all large organizations, they adopted Power BI Premium. However, they have provisioned only one Power BI Premium P1 node which has been showing signs for overutilization. In the process, I discovered they have purchased 40 Power BI Premium cores with 32 cores left unutilized! In other words, they used 1/5 of what they’ve been paying Microsoft as Power BI Premium fees. How did they arrive at this unfortunate situation?

A year or so ago, they used the Power BI Premium Calculator to estimate the licensing cost on their own. They plugged in 10,000 users and got a recommendation for 5 P1 nodes (or 40 cores). And that’s what they bought, assuming that they will get a cluster of five P1 nodes that would load balance the reports across nodes. When they set up Power BI Premium, they set up only one P1 capacity and all the important reports got in there. And these reports have been running just fine for a long time with thousands of users … The other 32 cores – sitting ducks.

Power BI Premium doesn’t currently load balance across nodes. Once you’ve licensed a certain number of cores, it does give you the flexibility to provision nodes of different sizes. So, with 40 licensed cores, you can set up 5 P1 nodes, or 2 P2 nodes and 1 P1 node, or one P3 node and 1 P1 node. Unfortunately, the flexibility ends there. Once you provision the capacity, the meter is running use it or not. And if you’re not using all these licensed cores, you still pay unless you manually scale down the capacity. I hope to see Power BI Premium Serverless sometimes in the future, where the service scales up and down on demand and you pay for what you really consume. This will void the decision on how much capacity and nodes you need, probably save you lots of money, and make Power BI Premium more affordable.
