Cloud storage services are associated with high latency variance, and degraded throughput which is problematic when users are fetching and storing content for interactive applications. This can be attributed to performance hotspots created by slow nodes in a storage cluster, and performance interference caused by multi-tenancy, and background tasks such as data scrubbing, backfilling, recovery, etc. In this paper, we present DLR, a system that improves the performance of cloud storage servicesdoi:10.1109/cloud.2017.15 dblp:conf/IEEEcloud/NoelL17 fatcat:xoryw66gcfdyzif37rmuyzomau
