Hardware Report: Amazon C5 instances (c5.large)

Amazon announced on 11/30/2016 the addition of Amazon EC2 C5 instances in early 2017 powered by Intel Xeon Skylake that comes with SGX capabilities. Here's the report from a c5.large running Ubuntu 16.04:

Because of the fact that is cloud infrastructure, getting access to tweak the BIOS seems highly unlikely. I tried installing the linux-sgx-driver, which did install but remains unused, and installed linux-sgx SDK & PSW, and the SampleEnclave code returns Intel SGX is not supported by this processor., which I believe is not technically true (instead of saying that SGX needs to get enabled through the BIOS).
Any ideas for things I could try or investigate further?
Thanks for the awesome work on this repo, BTW. Much appreciated!
Does anyone have suggestions around the possibility of modifying the BIOS and enabling SGX from the command line on Linux? My initial research shows that this is highly unlikely, and even if at all possible, the cloud providers would disallow it for security reasons. Would love to hear anyone's experience on this front.
I think the only provider that grants access to SGX is Azure:

Hope it helps!
Thanks @rolandomar. There is this post from Feb. 2018 that suggests Azure may have shut down that program :(
Hey Victor,
thanks a lot for investigating the SGX capabilities in AWS and Google! I can remember the official cloud vendor statements when I started working on SGX. However it is somehow sad that the technology isn't yet official supported. So the last hope for SGX in cloud environments is IBM bluemix and their cloud data guard. Try to sign up here.
I will update the index readme of this repo with this information.
Best regards
Lars
I signed up with them several days ago, and I'm in conversations with them. I haven't had a chance to post my hardware report on them yet. I'll do that next...
Thanks a lot for your input! I will close this AWS issue. If there is a new development regarding SGX on AWS feel free to reopen it.
A quick update on this issue: I talked to Google Cloud engineers some time ago, and they confirmed that they currently do not support SGX, and they have not immediate plans to support it, so we'll have to look elsewhere for cloud SGX infrastructure.
Can you comment on the following Google announcement (dated May 03,2018) on Asylo? (Gemalto claims to be using it as well):
[https://cloud.google.com/blog/products/gcp/introducing-asylo-an-open-source-framework-for-confidential-computing]
@hkpt16384: Asylo is a software framework to develop enclave applications across different hardware infrastructure, and it's open source, you can find it here: https://github.com/google/asylo
But asylo is a piece of software, it is unrelated to Google providing cloud infrastructure that supports hardware enclaves.
