Saw a little more of CBM at the European User Group yesterday and very interested/excited about the possibilities. We are also in CCM and having great success, mainly in AWS space as that has been our focus - Azure is polling daily but have been focusing on bigger wins for now. We have also added Dell Boomi connector inputs and created a charging model based on some agreed service catalogue pricing, recently we have introduced our support partner costs as well using consumption as a driver to allocate the fixed price managed service for AWS and Boomi which is working well. Its providing a loaded cloud costs where we have struggled with some of our other CT challenges... Not quite out the box, but very effective! :O)
Through daily analytics we have saved large sums by showing the impact of not scheduling or buying the wrong size product, but still need to do the scheduling manually :O(.... We encourage the projects to schedule switching off their services at end fo day in case they forget to but not to auto switch on, so at weekends it doesn't spin up and if there are morning huddles etc again not paying for those precious minutes.... until needed!
Using the Monthly TCO as post data cleanse (tagging is still an issue!) we have managed a really defensible 'Bill of IT esq' recharge for our cloud services and have it all end-to-end in CCM! PM uptake has been a good success as well with many logging in every day to check the impact of yesterdays project decisions.
We have custom built a few reports for the TBMO but largely out the box for the end user community.
