- zokier 2y agoIt 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 https://github.com/intel/pcm/blob/master/doc/FAQ.md#q11 or tables here https://www.intel.com/content/www/us/en/developer/articles/technical/intel-vtune-amplifier-functionality-on-aws-instances.html https://www.intel.com/content/www/us/en/developer/articles/t... dunno about others
