Does AWS oversubscribed CPU?

What is a good oversubscription ratio?
The acceptable oversubscription ratio should be 3:1 or even less e,. g., 2.5:1, to ensure there is no excessive bandwidth contention when all servers send traffic simultaneously. The oversubscription ratio increases with the number of servers in the fabric, and it is reduced by adding more spine switches to the fabric.
What is oversubscription in VMware?
Can you Overprovision memory in VMware?
VMware does things a little bit differently. While some might argue that Hyper-V doesn’t support “true” memory overcommitment, VMware actually lets VMs consume more virtual memory than is physically installed in the host. This is possible because of several memory management techniques that VMware uses.
What is Byol in AWS?
