WS-GAF Savas Parastatidis www.neresc.ac.uk WS-GAF • Aug2003 “A Grid Application Framework based on Web Services specifications and practices” paper used emerging technologies • Switched to stable ones but we are not discouraging an “experimentation track” • Not middleware • Design patterns/principles • Use stable technologies www.neresc.ac.uk 2 WS-GAF Application • We need to build large-scale Grid applications using Web Services in order to find out what is actually required • Aims • Define the characteristics of a “typical” Grid application • Demonstrate the applicability of the WS-GAF approach in building Grid applications • Learn from the challenges of constructing a truly global, distributed, scalable, loosely-coupled application • Working on a “typical”, global-scale Grid application with international partners • We encourage everyone’s involvement www.neresc.ac.uk 3 Applications • White dwarfs • • • • Bob Mann Jim Gray Johns Hopkins Steven Newhouse www.neresc.ac.uk 4 Searching for “White Dwarfs” • Jim Gray’s SkyServer • Combine info from other databases • Utilise computational resources • Visualise www.neresc.ac.uk We are looking for these 5 Applications • RFID-based • Security • GOLD • Databases – continuous queries – large amount of information www.neresc.ac.uk 6 WS-GAF Web Services Grid Application Framework (WS-GAF) http://www.neresc.ac.uk/ws-gaf Mailing list (>80 people from all over the world) [email protected] Join by sending a message to [email protected] including the following line in the body join ws-gaf YourFirstName YourLastName www.neresc.ac.uk 7
