Performance of network and computing resource sharing in federated cloud systems
Walter Cerroni · 2014
The increasing demand of computing, storage and communication resources by cloud-based applications is fostering new forms of infrastructure sharing such as cloud federations, which can take advantage of virtualization technologies and, in particular, of virtual machine live migration techniques. Such a scenario requires a quantitative characterization of the performance of the inter-data center communication considering possible limitations in both network and computing resource availability. This paper provides an analytical model for joint dimensioning of shared network and data center capacity in a federate cloud.
