Unikraft: Fast, Specialized Unikernels the Easy Way

Unikernels are famous for providing excellent performance in terms of boot times, throughput, and memory consumption, to name a few metrics. However, they are infamous for making it hard and extremely time-consuming to extract such performance, and for needing significant engineering effort in order to port applications to them. We introduce Unikraft, a novel micro-library OS that (1) fully modularizes OS primitives so that it is easy to customize the unikernel and include only relevant components, and (2) exposes a set of composable, performance-oriented APIs in order to make it easy for developers to obtain high performance.
