With expanding demand for Cloud computing, numerous Cloud providers are offering services. Benchmarking is extremely important to compare their performance. In this paper, the authors study the performance of two IaaS clouds eucalyptus 3 and OpenStack (version Essex) implemented on FutureGrid, a test bed that allows researchers to conduct experiments to understand the behavior and utility of cloud computing services. Phoronix Test Suite is utilized as a benchmark program to conduct diverse performance measurements on both the clouds. Besides the programs in Phoronix Test suite, time to launch instances, time to register images using scripts were also matched.
