The Future of the Grid and Globus: Beyond Web Services and OGSI

Steve Tuecke, Argonne National Laboratory

Abstract

Globus Toolkit(R) v3.0 was released in June 2003 with a complete implementation of the Web services-based Open Grid Services Infrastructure (OGSI) v1.0 specification, and a set of "Globus proprietary" Web/Grid services built on top of this OGSI basis. Our focus for the next 12-18 months is to standardize the functionality available in Globus Toolkit, as well as additional core, complementary functionality, and to make this available in a future version of the Globus Toolkit. With this foundation in place, we then expect the emergence of a rich ecosystem of collective layer services that exploit this common foundation. In this talk I will overview the current GT3 structure, explain the standards landscape to describe how I think these standards and the ensuing GT implementation will evolve, and discuss the transition from GT2 into this evolving GT3 setting. Emerging standards to be discussed include WSDL (W3C), OGSI (GGF), OGSI-Agreement (GGF), Web Services Distributed Management and Web Services Management Framework (Oasis), Data Access and Integration (GGF), data replication and federation, events and message queues, and job submission and reservation.

About the speaker: Steve Tuecke (pronounced Tee-key) is lead architect of the Globus Project(tm), responsible for the architecture and design of the Globus Toolkit(R) and for the Grid and Web Services standards that underlie it. He began working as a software developer for Ian Foster in 1990 in the Mathematics and Computer Science Division at Argonne National Laboratory. Since the beginning of the Globus Project in 1996, Tuecke has been responsible for building Foster's Distributed Systems Laboratory (DSL) at Argonne virtually from scratch into the premier Grid research and development group in the world, including staffing, management, and technology leadership. Since turning over management of the DSL in 2001, Tuecke has focused on Globus Toolkit architecture and design, Grid standards, and industry relationships.

Tuecke graduated Summa Cum Laude from St. Olaf College in 1989, receiving a B.A. in Mathematics and Computer Science. In 2002 he received Technology Review magazine's TR100 award, recognizing him as one of the world's top 100 young innovators. In 2002 he also was named to Crain's Chicago Business Forty Under 40, as one of the Chicago area's "best and brightest". In 2003 he was named (with Foster and Kesselman) by InfoWorld Magazine as one of its Top 10 Technology Innovators of 2003, as the "masterminds behind the technologies that are making the biggest splash and steering IT into the future". He is a leader in the Grid and Web services standards communities, including a member of the Global Grid Forum Steering Group, editor and co-chair of the Open Grid Services Infrastructure (OGSI) standard, and an author or participant of numerous other standards efforts including W3C WSDL (Web Services), GGF OGSI-Agreement (SLA negotiation), GGF Data Access and Integration, OASIS WSDM (service management), and IETF X.509 Proxy Certificates (security).
