Supersaturated Cloud for Multicore Systems

In cloud era, new cloud skill is required for IT specialists. Educational organizations such as University need to provide educational cloud for students. We are constructing private cloud based on super-saturated private cloud. The most important feature of our cloud is super-saturation, which is defined as allocating much more logical resource than physical resource. Super-saturated cloud is suited for Multicore systems and realizes to run about 8 times instances than conventional cloud. The performance decreases a little but the cost decreases drastically. We have experiences of using supersaturated cloud for education. For such purposes, it is important to activate many instances at one time in case of beginning classes. In this paper, we evaluate activation time of many instances. As this result, activation time of 64 instances can be reduced to 17 min.
