Energy and power usage data in the cloud

Getting power usage data in cloud is a tough topic and one of the reasons projects such as Cloud Carbon Footprint exist. Typically cloud vendors, especially hyperscalers, do neither supply energy consumption data of the whole machine from PDUs or similar, nor do they provide access to CPU internal energy data like for instance RAPL.
