Is this better than Firecracker? I was thinking about using that but it needs nested virtualization and the servers that support that aren't as good of a value. Anyone know a good option for nested virtualization that is inexpensive?
Hetzner is really cheap but not sure about the cost effectiveness for the dedicated servers. Actually I think what I saw was that I couldn't get the one I wanted in a US datacenter.
The cited startup time is better than Firecracker but it's not a better tool than Firecracker (for a start only claims to be a PoC, "contains only the necessary parts for realistic benchmarking"). Looks like it's based on RISC-V emulation so the approach seems unlikely to get performance comparable to Firecracker.
You might look into gVisor if you're running containerized workloads on a host without virt support (such as a vm without nested virtualization support).
Absolutely not! It's better to use something backed by KVM, so that you can use all the features of the CPU. This is just a proof-of-concept that was fun to make.
