On Data Placement in Distributed Systems
João Paiva, Luı́s Rodrigues · ACM SIGOPS Operating Systems Review · 2015
Data placement refers to the problem of deciding how to assign data items to nodes in a distributed system to optimize one or several of a number of performance criteria such as reducing network congestion, improving load balancing, among others. This document reports on our experience when addressing this problem in distributed systems of different scales, namely: medium size datacenter-scale and internet-scale systems.
