Summary

AWS Nitro System, first launched in 2017, is a combination of purpose-built hardware and software solutions that have underpinned all AWS EC2 instances since the beginning of 2018. It is AWS’ innovative re-imagining of virtualization infrastructure and traditional hypervisors and how they protect the physical hardware, bios- and customer content. Based on dedicated custom-designed building blocks, the Nitro System breaks apart those traditional virtualization functions and offloads them to dedicated hardware and software. Customers benefit by having reduced costs and better performance, too, due to the lightweight hypervisor, as practically all of the resources of a server are dedicated to customer instances.

Furthermore, Nitro provides enhanced security and privacy in the form of confidential computing, the building block required for multiparty collaboration and multiparty security out-of-the-box. This report clarifies the language used by AWS and how it relates to the language used by other voices in the secure and private compute community. Cybersecurity specialist, the NCC Group, has recently conducted an architecture review of the Nitro System and validated AWS’ security claims and confidential compute capabilities. AWS has even added these claims to its customer service terms.
