CSR: Small: The Pocket Datacenter

Research and development in cloud-based distributed systems is currentlyhindered due to the incredible difficulty of running such systems atscale. The Wisconsin Pocket Datacenter (PoD) project directly addresses thisdilemma by enabling researchers and developers to run large-scale distributedsystems on modest hardware resources. The key novel idea behind PoD is dataelision, which removes actual application data from the underlying disks,memories, and network transfers of the distributed system under test. PoD thusenables many virtual instances of such a system to be run upon just a fewphysical machines, thus making testing, debugging, and in general developmentsimpler, faster, and less resource-intensive.Cloud-based distributed systems represent a critically-important piece ofmodern computing infrastructure. As users and corporations migrate their dataand computation into such facilities, it is increasingly important to ensurethat such systems operate correctly and efficiently. PoD enables developers todebug existing systems and test new designs without excessive hardwareresources; with such a tool in their workbench, system developers will be ableto more readily build and test the next generation of cloud-based systems tosupport the needs of a growing percentage of society.
