1. Grids 2003 The Great Academia/Industry Grid Debate Dan Fay | Microsoft Research Grid, grid, everywhere a Grid Blocking out the scenery, breaking my mind Solve this! Don't use that! Can't you use the Grid? (apologizes to the Five Man Electrical Band)

2. What is a Grid? “The Grid”? Everyone has a definition – Grid community, Scientists, Industry, companies, products & customers Are Grids only about computations? What does supporting “the Grid” mean? What does it mean to be Grid enabled? Ie. Internet enabled Internet parallels – captures the imagination, as well as the naming (ie. internet*****,.com, i****, e****, ****grid, etc) A lot of interest – a lot of hype ie. “The Grid will solve it” Internet – Standard protocols Easily implemented on any platform Wide spread industry support Web Services are about making the Web/Internet programmable

3. Grids = “Internet-scale distributed computing” – Jim Gray Web Services is the way to do Internet-scale distributed computing. Live examples – TerraServiceTerraService – over 15 TB of images & data Turned into a Web Service in 3 days – http://terraservice.nethttp://terraservice.net SkyServer SkyServer - Sloan Digital Sky Survey – map a large part of the universe – Federates Astronomy data from 10 DB’s around the world SkyQuery http://www.skyquery.net/http://www.skyquery.net/ Web Services moving forward (beyond SOAP, XML, & HTTP) Web Services Architecture - Reliable, Secure, & Transacted Set of specifications (WS-*) from MS, IBM, and others to put more “smarts” at the application level – transport neutral GGF9 Discussion around refactoring OGSI on top of Web Service specs Grids are Web Services Get standardization and implemented specifications Develop on top of Web Services Architecture Leverage industry/commercial tools

4. Business issues around Grids Beyond the Technical Issues Naming/Definitions Specifications Build on "secure, reliable, transacted" Web services architecture Business Issues - Possible Obstacles to wide spread adoption Different from Academic & research issues Business opportunity/justification Business model Trust / Privacy Security / IP Software licensing Batch vs real-time “Can I or am I willing to run mission critical apps on the Grid?” “Will we allow external code to execute on internal resources?” Will this limit “Grids” to inside Enterprises & Partner Grids?
