Abstract

Both cloud and GRID are computing paradigms that manage large distributed resources, and currently there is a lot of interest in their integration. An integrated architecture cloud-GRID requires fine-grained access control and identity federation among untrusted distributed domains in the cloud. This paper deals with the trade-off between security and performance in such architectures, comparing the overhead introduced by cloud services with different security levels. The quantitative results obtained in PerfCloud, an existing cloudgrid infrastructure, are presented and discussed.
