Abstract:
Despite of their rising popularity, current cloud storage services and cloud-backed storage systems still have some limitations related to reliability, durability assurances and inefficient file sharing. We present SCFS, a cloud-backed file system that addresses these issues and provides strong consistency and near-POSIX semantics on top of eventually-consistent cloud storage services. SCFS provides a pluggable backplane that allows it to work with various storage clouds or a cloud-of-clouds (for added dependability). It also exploits some design opportunities inherent in the current cloud services through a set of novel ideas for cloud-backed file systems: always write and avoid reading, modular coordination, private name spaces and consistency anchors.
