Existing partial geo-replication systems do not always provide optimal cost or latency, because their replication decisions are based on statically established data access popularity metrics, regardless of the application types. We demonstrate that additional reduction in cost and latency can be achieved by 1) using the right object attributes for making replication decisions for each type of application,...
Interactive use of cloud services is of keen interest to science end users, including for storing and accessing shared data sets. This paper evaluates the viability of interactively using two important cloud services offered by Amazon: SQS (Simple Queue Service) and S3 (Simple Storage Service).
