Abstract: 

Emerging Cloud Storage API standards, including CDMI and OpenStack Storage, are oriented towards REST APIs that allow streaming object access. Several features taken for granted in traditional filesystem APIs like POSIX and Windows are not present in this new paradigm. Examples include random file updates and directory operations. Bridging technologies must address this disconnect to provide full functionality in a performant manner. We detail the techniques we have used in order to make cloud storage file drivers functional and efficient for both every day user interaction and high-throughput, low-latency applications.
Learning Objectives

Learn about techniques to overcome functional limitations of cloud storage APIs.
Discover how file system bridge drivers solve requirements for both human users and batch processing applications.
Learn about required caching techniques and how to make them work better for high throughput workloads.
