Abstract:In a virtualized computer system with shared resources, consolidated virtual services (VSs) fiercely compete with each other to obtain the required capacity of resources, and this causes significant system's performance degradation. The performance of input output (I/O)‐bound applications running inside their own VS is mainly determined by the total time required to schedule every read/write request, plus the actual time needed by the device driver to complete the request. To achieve a right performance isolat… Show more
“…In the paper by Farahabady et al, 8 the authors studied how to efficiently schedule the shared resources and keep the system's performance for virtual services in a virtualized computer system. They proposed a resource allocation controller which uses a fully polynomial‐time randomized approximation scheme to enable performance isolation of concurrent I/O requests.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
