Yes, we can confirm that. We let you generate and run unikernels for JVM apps on AWS at https://boxfuse.com
Disclaimer: I am the founder
Interesting. Is it open source?
No. It is SaaS with an installable client. But we do have a free tier that is perfectly aligned to the AWS free tier. Also there is no lock-in per se as you give Boxfuse an app in a standard format (.jar/.war) and Boxfuse turns it into an image in a cloud native format like an AMI for AWS. All this with just a single command.
Any chance you'll support Rust or Go in the future? Our company doesn't deal with the JVM at all - mostly Python and Go currently.
unfortunately other providers, like DigitalOcean, don't seem to support rumpkernels or unikernels.
I believe the problem isn't so much that DO, etc., don't support unikernels, as that they use something other than Xen as the virtualization layer; something-other-than-Xen is still on the to-do list of the unikernel projects.
The rump kernel unikernel (rumprun) will happily work on actual hardware. It's a bit hazy if that's a unikernel or an embedded system in that case (and what's the difference anyway?), but to avoid hairsplitting, you can replace the hardware with KVM and off you go.
