NEC’s presentation about Unikraft at P99 CONF

On the 7th of October, the P99 CONF took place as a new online industry event for high performance, low latency and high availability engineering. Felipe Huici, from NEC Laboratories, a partner of the UNICORE Consortium, gave the presentation “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.

In this talk, Huici introduced Unikraft, 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.

The 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).
