ABSTRACT
The backbone of IT infrastructure is evolving towards a service-oriented model, in which distributed resources (software services, virtualized hardware infrastructure, data repositories, sensors, and network overlays) can be composed as a customized IT service on demand. In particular, cloud computing infrastructure services manage a shared ``cloud'' of servers as a unified hosting substrate for diverse scientific applications, using various technologies to provision servers and orchestrate their operation. At the same time, high-speed networks increasingly offer dynamic provisioning services at multiple layers. Network-connected clouds offer a general, flexible, and powerful model to scale up computing power for data-intensive science applications running at multiple cloud sites. The software produced in this project offers interfaces and control policies for application-driven orchestration of federated clouds interconnected by advanced networks.
The project develops software to link cloud computing clusters to other cyberinfrastructure resources through dynamically provisioned networks. A principal focus is to extend popular cloud infrastructure software with hooks to connect provisioned machine instances running in the cloud to external resources through dynamic circuit networks. The project enables cloud applications to dynamically request compute resources at multiple points in the network, together with bandwidth-provisioned network pipes to interconnect them and link them with other services and data repositories. The orchestration framework is based on the Open Resource Control Architecture (ORCA), an extensible platform for dynamic leasing of resources in a shared networked infrastructure. The resource allocation policies are enabled through semantic resource descriptions and extended intelligent SPARQL queries. Driving applications for this project are MotifNetwork, IMG/JGI and Supernova Factory and sensor networks linked to cloud resources (CASA). Development and demonstrations leverage the Breakable Experimental Network (BEN, a multi-layer optical network testbed located in North Carolina), NLR and ESNet.
PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
The main outcome of the "Missing Link" project was the development of a suite of technologies that enabled the creation of a networked cloud testbed called ExoGENI (http://www.exogeni.net).
The testbed consists of a number of campus clouds interconnected by programmable networks, like Internet2 (http://www.internet2.edu) and ESnet (http://www.es.net). These clouds are distributed across the US and the world and include computational, storage and network resource contributed by ExoGENI's international partners.
The technologies developed in the "Missing Link" project are making it possible for experimenters university students, faculty, researchers to rapidly create complex distributed "virtual networks" that support a variety of experiments in distributed systems and network science. The testbed also serves as a blueprint for developing the future architecture of widely distributed cyber-infrastructure spanning the globe, easily accessible by a multitude of researchers from different branches of science and helping them be more productive in their discovery.
One of the important outcomes of the project is the interest that the technologies enabling this type of rapid creation of on-demand cyber-infrastructure is getting from computational scientists struggling with configuring and running their computations on the traditional monolithic computational infrastructure. The ExoGENI technologies have deep implications to a number of sciences and sectors of industry struggling with the "big data" problems astronomy, physics, chemistry, bioinformatics and healthcare.
