Grid computing enables scientists to combine and share the computer resources from multiple administrative domains to solve complex scientific problems. As a result, Large-scale collaborative science is becoming increasingly common, involving thousands of collaborators distributed across the globe and generating massive amounts of data that must be transferred across wide area networks. In practice orchestration of such transfers is technically challenging. One key issue is the frequent need to exploit parallelism in multiple dimensions. Another is dealing with failures of various sorts. Globus Online is a new direction that attempts to combine the powerful ideas and technologies of hosted services with existing data transfer engines (in particular, GridFTP) to provide a robust, reliable, secure, and highly monitored environment for file transfers that has powerful yet easy-to-use interfaces. In this talk, I will describe the motivation for developing Globus Online and demonstrate its capabilities.
