Unikernels are poised to become the next big thing in microservices after Docker containers. Here’s a look at some of the cool things you can do with unikernels. First, though, here’s a quick primer on what unikernels are, for the uninitiated. Unikernels are similar to containers in that they let you run an app inside a portable, software-defined environment. But they go a step further than containers by packaging all of the libraries required to run the app directly into the unikernel.
The result is an app that can boot and run on its own. It does not require a host of any kind. That makes unikernels leaner and meaner than containers, which require a container engine such as Docker and a host operating system such as Linux to run.
