KAAS: Kernel as a Service

Advances in cloud computing have led to advances in infrastructure, platforms and user applications. But the operating system space hasn't really kept pace with these advancements. In this paper we propose a model for cloud OS with Kernel As A Service (KAAS) offering. We describe the notion of KAAS and use it as a building block for developing Cloud OS. The KAAS model serves as the basic enabler for cross kernel switching, this offers an attractive set of possibilities like load balancing across kernels, fault resilience against kernel failures etc. The design, implementation and performance study of the this Cloud Operating System (SICLOPS) is presented in the paper.
