In order to minimize storage costs, how to optimally allocate data in a minimum number of servers without violating latency guarantees remains to be a crucial issue for the cloud provider to tackle. In this paper, we study the latency-sensitive data allocation problem for cloud storage. We model the data access time as a given distribution whose Cumulative Density Function (CDF) is known, and prove that this problem is NP-hard. To solve it, we propose both exact Integer Nonlinear Program (INLP) and Tabu Search-based heuristic. The proposed algorithms are evaluated in terms of the number of used servers, storage utilization and throughput utilization."],["dc.identifier.doi","10.23919/INM.2017.7987258"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13221"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.publisher","IEEE"],["dc.relation.conference","2017 IFIP/IEEE Symposium on Integrated Network and Service Management (IM)"],["dc.relation.eventend","2017-05-12"],["dc.relation.eventlocation","Lisbon, Portugal"],["dc.relation.eventstart","2017-05-08"],["dc.relation.isbn","978-3-901882-89-0"],["dc.relation.isbn","978-3-901882-89-0"],["dc.relation.ispartof","2017 IFIP/IEEE Symposium on Integrated Network and Service Management (IM)"],["dc.relation.orgunit","Gesellschaft für wissenschaftliche Datenverarbeitung"],["dc.title","Latency-Sensitive Data Allocation for cloud storage"],["dc.type","conference_paper"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
