Performance Evaluations of LXC Based Educational Cloud in a Bare Metal Server

Cloud computing is becoming increasingly popular and can be for used for education purposes. We propose an educational cloud based on the supersaturation method. In cloud computing, the supersaturation method is a method of assigning many more logic resources than physical resources. The cost is more important in a supersaturated cloud than the performance. Linux containers such as LXC have recently been developed, and are especially suited to supersaturation. We built a supersaturated cloud on an Amazon EC2 (elastic compute cloud) and evaluated its performance. We used the installation of Ruby as a benchmark. In our results, the response time of a bare metal server linearly increased up to 370 instances. Therefore, we conclude that bare metal server is suited to supersaturated clouds with reasonable costs.
