An Unikernels Provisioning Architecture for OpenStack

Abstract

Recently, the development of Unikernels, extremely light operating systems constructed exclusively for virtualized environments, has emerged as another alternative to cloud platforms. Unikernels encourage new paradigms and provisioning techniques, such as immutable servers and microservices. This paper proposes an optimized architecture for Unikernels provisioning in OpenStack. The architecture is based on OSv Unikernels and experiments demonstrated that it can attain satisfactory results, reducing the time of the entire deployment workflow, from the compilation to the initialization of the Unikernels in the compute node.
