The CPU is the third such project that I'm aware of, also checkout their Nitro hypervisor and disk interface: http://www.brendangregg.com/blog/2017-11-29/aws-ec2-virtualization-2017.html http://www.brendangregg.com/blog/2017-11-29/aws-ec2-virtuali... I know they did their own networking hardware, but I don't know if it was done by the same team that did this CPU and Nitro.
