What can science cyberinfrastructure learn from commercial IT?

Abstract: Commercial information technology (IT) has changed dramatically over the past decade, with profound consequences for both consumers and the industry as a whole. Many companies outsource much of their IT to cloud providers. Software developers increasingly target cloud platforms rather than operating systems. Online services provide access to an amazingly rich set of capabilities. These changes have slashed costs, reduced barriers to access and entry, and in so doing spurred tremendous innovation. Science cyberinfrastructure, in contrast, seems stuck in the 20th Century. I discuss lessons that we might learn from industry and suggest new principles that the scientific community might consider when designing cyberinfrastructure for the 21st Century.

Revisiting the Anatomy and Physiology of the Grid

Abstract: The "Grid" as defined by Foster and Kesselman was a unifying architecture that engendered a new generation of distribution computation, data sharing, and science. Along the way many “grid” technologies were developed, but their mapping to the principal architecture envisaged by the Grid’s authors was never concretely specified.

In this talk I will present a decade’s long study of 18+ technologies that claim to be "grid"; and ask the question “what makes a grid technology a grid?” This question, along with empirical research using topical software architectural recovery techniques; code and program analysis; clustering and information retrieval, allow the definition of an updated grid architecture that more uniformly captures what was built over this timeframe.
