One problems with unikernels is a lack of debugging/tracing tools (like Dtrace/eBPF): https://www.joyent.com/blog/unikernels-are-unfit-for-production https://www.joyent.com/blog/unikernels-are-unfit-for-product...
- nickik 9y agoThat blog post is pretty crappy. See discussions here: https://news.ycombinator.com/item?id=10953766 https://news.ycombinator.com/item?id=10953766
- citrin_ru 9y agoThe blog post has some flawed arguments, but still there is almost no observability/tracing tools for unikernels.
- nickik 9y agoSome do, some don't. But to link to this as the 'super-argument' every-time somebody mentioned unikernels is pointless and wrong. Its also simply not relevant for many cases.
- equalunique 9y agoTry it with the LING Erlang-on-Xen unikernel and see for yourself if it's not debugabble. Looks like they've got a solution for dubugging: https://twitter.com/erlang_on_xen/status/641628659657371648 https://twitter.com/erlang_on_xen/status/641628659657371648
