vStarCloud: An Operating System Architecture for Cloud Computing

In recent years, cloud computing is increasingly abstracting away the operating system, allowing developers to focus higher up the stack on applications, not infrastructure. In this position paper, we analyzed the deficiencies of the traditional operating systems in the cloud environment and the features of existing cloud operating systems. We have proposed an operating system architecture for cloud computing which is called vStarCloud, and implemented a prototype to show that our approach is promising. We describe how common problems for the cloud environment can be effectively solved by POSIV (Portable Operating System Interface of vStarCloud) interface. The prototype of vStarCloud provides the ability of virtual machine management and MapReduce job management. Then we discussed how to cope with the challenges of the new cloud operating systems.
