&quot; I&#x27;m glad it was written, because I&#x27;ve seen nothing but hype for Unikernels on Hacker News (and in ACM, etc.) for the last 2 years. &quot;<p>That much is true. I&#x27;m countering what I can where it gets overblown. Just part of something going mainstream... crowd effects and so on...<p>&quot;The only thing I disagree with in the article is debugging vs. restarting. In the old model, where you have a sys admin per box, yes you might want to log in and manually tweak things. In big distributed systems, code should be designed to be restarted (i.e. prefer statelessness). That is your first line of defense, and a very effective one.&quot;<p>Additionally, there&#x27;s no inherent reason that I see that unikernels are impossible to debug. We can debug everything from live hardware up to apps with existing tooling. So, if unikernels are lacking, it just means they&#x27;re still young and nobody has adapted proven techniques to debugging them. I imagine the simple ones on simpler HW will make that even easier.
