The increasing popularity of cloud storage is leading organizations to consider moving data out of their own data centers and into the cloud. However, success for cloud storage providers can present… (More)
This paper considers replication strategies for storage systems that aggregate the disks of many nodes spread over the Internet. Maintaining replication in such systems can be prohibitively… (More)
OceanStore is an Internet-scale, persistent data store designed for incremental scalability, secure sharing, and long-term durability. Pond is the OceanStore prototype; it contains many of the… (More)
Current Infrastructure as a Service (IaaS) clouds operate in isolation from each other. Slight variations in the virtual machine (VM) abstractions or underlying hypervisor services prevent unified… (More)
Conventional datacenters, based on wired networks, entail high wiring costs, suffer from performance bottlenecks, and have low resilience to network failures. In this paper, we investigate a… (More)
Many wide-area storage systems replicate data for durability. A common way of maintaining the replicas is to detect node failures and respond by creating additional copies of objects that were stored… (More)
The global network of datacenters is emerging as an important distributed systems paradigm — commodity clusters running high-performance applications, connected by high-speed ‘lambda’ networks across… (More)
The computing world is experiencing a transition from desktop PCs to connected information appliances, which — like the earlier transition from mainframes to PCs — will profoundly change the way… (More)
