Your company spent a gazillion dollars purchasing the next Enterprise Software (which, by the way, is a dying class of software – being obsoleted by Software as a Service).
The licensing of the software requires you to pay per core – per physical cores.
To save money (amongst other benefits), you consider deploying (hosting) your enterprise software on the cloud – perhaps EC2 instances on AWS.
Nowhere, can you find even a MENTION of PHYSICAL cores. Everything is virtualized – and the best you can do is virtual cores.
So – how does your license for physical cores carry over to the cloud – which only understands virtual cores?
Fortunately, AWS has addressed this issue – by creating a mapping between cores and the type of AWS instance that would meet those requirements.
