Unikernels are machine images constructed through the compilation of the application code, a minimum set of operating system dependencies, the machine configurations and respective drivers. The unikernel represents the smallest subset of code required to run the application, giving us portable applications with smaller footprint, less overhead, smaller attack surface, and faster boot times than traditional operating systems. UniK (pronounced you-neek) enables software developers to compile applications into different unikernels creating extremely lightweight, efficient application instances. These single-purpose images can then be deployed on a variety of cloud providers, embedded devices (IoT), as well as a developer laptop or workstation. A UniK plugin is available for Cloud Foundry and kubernetes to enable continuous deployment of applications as unikernels. This allows Spring Boot developers to take advantage of unikernels within the ease and power of the Cloud Foundry deployment toolchain.
