Cloud-Native File Systems


Remzi Arpaci-Dusseau and Andrea Arpaci-Dusseau, University of Wisconsin-Madison; Venkat Venkataramani, Rockset, Inc.


We present the case for cloud-native system design, focused on the creation of CNFS, a local file system built specifically for the cloud era. We first present numerous storage and CPU design principles that any cloud-native storage system should consider; we demonstrate the utility of these principles through the design of CNFS. CNFS is a hierarchical, copy-on-write file system that migrates data and metadata across cloud storage volumes to meet user objectives, and harnesses remote CPU workers to perform critical background work such as migration and compression.
