Unikernels Aren’t Dead, They’re Just Not Containers

For years we’ve been observing the Unikernel concept gather and then lose steam. Unikernels where put forward as the next evolutionary step beyond containers. However, unikernels are fundamentally different beasts and they really have very little in common with containers. I’ll try to look away from the hype and look at the fundamentals of unikernels, what are the principle differences between them and general purpose operating systems and what applications follow this. 

I’ll also look in depth at one of the IncludeOS application we’ve built, how we built it and how it has worked out in production.
