Adaptive and Dynamic Funnel Replication in Clouds

The authors consider the problem of strongly consistent replication in a multi data center cloud setting. This environment is characterized by high latency communication between data centers, significant fluctuations in the performance of seemingly identical Virtual Machines (VMs) and temporary disconnects of data centers from the rest of the cloud. In this paper, they introduce the adaptive and dynamic Funnel Replication (FR) protocol that is designed to achieve high throughout and low latency for reads, to accommodate arbitrary latency/throughput tradeoffs for writes, to maximize performance in the face of VM performance variations and to provide high availability for read requests despite network partitions.
