An open source project sponsored by EMC allows applications written in C/C++, Java, Go, Node.js, and now Python to be transformed into unikernels -- operating systems that do nothing but run a single, dedicated application.
UniK (pronounced "unique") is one of several experiments with unikernels to see if their minimal footprint and security profile can work better than containers for some workloads.

UniK promises a simple way for an organization to find out if a unikernel version of a given app runs better than its containerized counterpart. The workload is about the same as would be required to deploy the app as a container.
