A novel cloud bursting technique

Companies (even SMEs) are roused by the success and potentials of the public clouds and they build their own private cloud infrastructures. Thus, they open the door to an easier and more flexible way for outsourcing their IT services than before. However, the currently available software solutions still do not provide seamless extensibility by cloud bursting. Therefore, the IaaS users have to prepare their images in every infrastructure. This paper presents the criteria for idealistic cloud bursting and introduces a method that overcomes the current cloud bursting issues (e.g. different administration domains and networking policies). The proposed technique uses nested virtualization, that reduces the complexity of the cloud bursting procedure. Furthermore, we have evaluated the applicability of our design by performance tests. The evaluation showed that the seamless extensibility has a cost of 5-10% overhead on the deployment time.
