Brief Announcement: Consistency and Complexity Tradeoffs for Highly-Available Multi-Cloud Store
Abstract
An emerging
multi-cloud storage paradigm suggests replicating data across multiple cloud storage
services, potentially operated by distinct providers. In this paper, we study the impact of the storage
interfaces and consistency semantics exposed by individual clouds on the complexity of the reliable
multi-cloud storage implementation. Our results establish several inherent space and time tradeoffs
associated with emulating reliable objects over a collection of unreliable storage services with varied
interfaces and consistency guarantees.
