alt Hacker NewsDo any cloud hosting providers make io_uring available? Or are they all blocking it due to perceived security risks? I think I have a killer use case and would love to experiment - but it’s unclear who even makes this available.

Short answer: yes.
I guess you are thinking of iouring being disabled in dockeresque rumtimes. This restriction does not apply to a VM, specially if you can run your own kernel (e.g. EC2).
Experiment away!
Adding to the answer from cptnntsoobv: All major cloud providers (AWS, Azure, GCP) and also smaller providers (e.g., Hetzner) support io_uring on VMs. We ran some tests on AWS, for example. The experiments in the paper were done on our lab infrastructure to test io_uring on 400G NICs (which are not yet widely available in the cloud)
