Sorry, I wasn't trying to suggest that all cloud vendors are pushing
Graphene, but rather than SGX enabled platforms became a commodity
product, users will end up using Graphene-like applications.

Let me provide an example:
https://www.alibabacloud.com/blog/protecting-go-language-applications-with-the-graphene-library-os-on-intel%C2%AE-sgx%C2%AE-secured-alibaba-cloud_594889
- a "practical" guide on how to run Graphene in production environment
   on one of the big cloud vendor platforms.
