The open source Unikraft project is proud to announce that its paper titled “Unikraft: Fast, Specialized Unikernels the Easy Way” has not only been accepted at Eurosys, one of the top systems conferences in the world, but that it has been bestowed with the prestigious Best Paper Award.
In addition, the paper has received the conference’s 3 reproducibility badges, meaning that the results in the paper have been reproduced by independent reviewers; you can even try the experiments out yourself here:
Unikraft’s main goal is to bring unikernels, specialized virtual machines able to provide excellent performance, into the mainstream. Unikraft is a novel micro-library OS that fully modularizes OS primitives so that it is easy to customize the unikernel and include only relevant components and exposes a set of composable, performance-oriented APIs in order to make it easy for developers to obtain high performance. Our evaluation using off-the-shelf applications such as nginx, SQLite, and Redis shows that running them on Unikraft results in a 1.7x-2.7x performance improvement compared to Linux guests. In addition, Unikraft images for these apps are around 1MB, require less than 10MB of RAM to run, and boot in around 1ms on top of the VMM time (total boot time 3ms-40ms). The full paper can be found here:
Beyond the paper, we have put a lot of work into developing kraft, a tool that makes it easy to build and start Unikraft-build unikernels. Further, we are in the process of integrating Unikraft with major monitoring and orchestration tools such as Kubernetes and Prometheus, so stay tuned for much more!
Unikraft is part of the Xen Project, a hosted project at the Linux Foundation and can be found at www.unikraft.org. We’d be more than grateful if you took Unikraft out for a spin and gave us feedback on what you think. Contributions are, of course, more than welcome!
