Nitro is good! And showcases a great many of the foundational architectural concepts in PCC.
But there is a major difference that is germane to the topic of Apple’s investment in US server manufacturing: The hardware root of trust. Hardware tampering is the weak point and afaik AWS doesn’t describe any process to certify their supply chain integrity. I think the most they’ve done is commission a review of their architecture document.[1] PCC actually has an auditor sign each server node in the datacenter.
Thank you for mentioning them though. It’s an important advancement in generally available confidential computing infrastructure.
