Performance evaluation of popular Cloud IaaS providers

Cloud computing has become a compelling and emerging computing model for delivering and consuming on demand computing resources. In this paper, we study and compare the performance of three popular Cloud IaaS (Infrastructure as a Service) providers. These three popular Cloud IaaS providers include Amazon EC2, ElasticHosts, and BlueLock. The performance is studied in terms of execution time of CPU-bound processes, size of memory bandwidth, and speed of read write disk I/O. To make the comparison fair, we strived to create virtual server on each of the providers with similar hardware and system configurations. Experiment results show that the performance of these selected servers varies with regard to different benchmarks.
