I was happy to see Clive, and I imagine a RUMP implementation or other unikernel that supports Rust won't be far away. Being able to compile Go or Rust to metal byte code is absurdly sexy.

I don't know how AWS will meter it yet (yup, I love AWS) but I sure hope they're following this trend. AWS support would put so much energy behind this path forward.

Isn't AWS built on XEN? I think the MirageOS folks have said you could deploy one of their unikernel apps on AWS as-is.

Yes it is, and AWS already supports unikernels.

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.

Yes, we can confirm that. We let you generate and run unikernels for JVM apps on AWS at https://boxfuse.com

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.

Yeah, like Erlang on Xen... it's ready to deploy to AWS
