Unikernels are unfit for production

简介

Bryan Cantrill, CTO of Joyent, really crystallized the gross feelings that have been rolling around in my mind with regard to unikernels. I would point colleagues to this article if they suggested we should deploy unikernel applications. He makes lots of good points, especially this one:

Unikernels are entirely undebuggable. There are no processes, so of course there is no ps, no htop, no strace — but there is also no netstat, no tcpdump, no ping!

I find the implicit denial of debugging production systems to be galling, and symptomatic of a deeper malaise among unikernel proponents: total lack of operational empathy.
