Virtual machines, containers, and unikernels. What are the differences? What is a unikernel anyways?
While virtual machines and containers get tossed around a lot in IT circles a new term has started entering the vernacular - unikernels - but what are they? Unikernels are a method of deploying software. They contain a given software application and the bits of the operating system that is needed boiled down to a very small lightweight secure virtual machine. Unlike containers, unikernels are at the end of the day, just virtual machines, albeit special tiny ones. Sometimes the VM can be ten to twenty megabytes.
