Disclaimer: I work at AWS, primarily in the compute space, but I'm not speaking in an official capacity.

As fguerraz mentioned, modern AWS instance families are basically all powered by Nitro, which refers to the ecosystem around the hypervisor and hardware acceleration cards utilized. https://aws.amazon.com/ec2/nitro/

Thank you very much! I thought nitro referred to the bare metal offering only.
