Not to diminish this work, but I think it's worth noting that it's increasingly possibly to launch new VMs extremely quickly too. FreeBSD/Firecracker can reach userland in 33 ms, and the OSv unikernel boots in under 10 ms.
I think increasingly we'll see Firecracker used with EC2-like setups of "create a disk image with everything preinstalled and then boot it" rather than using snapshots of running (suspended) VMs.
