Indeed, it's a very interesting space to explore. You get proper isolation at the "hardware" level, with performance and efficiency probably not very far from containers, or at least good enough for most use cases (with VT-x, etc.). Some of the issues of containers disappear (cross-platform support, for one), but we gain others instead, which prohibits me from attempting to use this in production for the immediate future. (Side note: is anyone actually using unikernels in production today? Please share your experience.) It took us quite a while to get the orchestration part right for containers, and even today, a lot of companies struggle with it. Not to mention writing tools for storage management, debugging, etc. We need similar tooling for unikernels+VMs, and I haven't seen such initiatives yet. That's OK, it's still a young platform, but I'll definitely be keeping my eye on it.
