A Performance Analysis of EC2 Cloud Computing Services for Scientific Computing

Abstract: Abstract. Cloud Computing is emerging today as a commercial infrastructure that eliminates the need for maintaining expensive computing hardware. Through the use of virtualization, clouds promise to address with the same shared set of physical resources a large user base with different needs. Thus, clouds promise to be for scientists an alternative to clusters, grids, and supercomputers. However, virtualization may induce significant performance penalties for the demanding scientific computing workloads. In th… Show more

“…Therefore, traps can be minimized for imbalanced environments and assistance can be given to users in more difficult decisions when the environments have similar performance by using an advisory tool as the one proposed in this paper. (2) in an imbalanced environment, the cutoff function must take into account the relative speeds of both the cloud and local environments. We empirically found out that this relationship follows an exponential decay, i.e.…”

“…Virtualization can improve overall system security and reliability by isolating multiple software stacks on their own VMs [16]. The clouds provide an alternative for clusters, grids, and supercomputers to the scientist [17]. Cloud computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services.…”
