This paper describes a Bioinformatics Software Defined Network Exchange (SDX) or BioSDX, which has been designed, deployed, and demonstrated by a multi-organizational research consortium to enable bioinformatics knowledge discovery supported by dynamic networking services. This BioSDX uses precision networking to support precision medicine. The BioSDX is based on recent technical developments in infrastructure...
More and more virtual machine (VM) images are continuously created in datacenters. Duplicated data segments may exist in such VM images, and it leads to a waste of storage resource. As a result, VM image deduplication is a common daily activity in datacenters. Our previous work Crab is such a product and it is on duty regularly in our datacenter. The size of VM images is large and the amount of VM...
What is a cloud application precisely? In this paper, we formulate a computing cloud as a kind of graph, a computing resource such as services or intellectual property access rights as an attribute of a graph node, and the use of a resource as a predicate on an edge of the graph. We also propose to model cloud computation semantically as a set of paths in a subgraph of the cloud such that every edge...
Cloud computing is an emerging computing paradigm. It aims to share data, calculations, and services transparently among users of a massive grid. Although the industry has started selling cloud-computing products, the software engineering infrastructure and application model are still unclear. In this paper, we compare cloud computing with service-oriented computing and pervasive computing. Both the...
