do cloud providers give full, unrestricted access to hardware performance counters?
It depends. On AWS you can get "metal" instances where afaik you get pretty much unrestricted access. In addition on certain instance types/sizes you get access to virtualized counters (vPMU). See Q11 here https://github.com/intel/pcm/blob/master/doc/FAQ.md#q11 or tables here https://www.intel.com/content/www/us/en/developer/articles/t...
dunno about others
