  1. Globus, CoG Kit, Web portals, and Road to Grid Fugang Wang Grid Seminar II, Fall 2008 Oct. 2008

  2. Agenda • Approaches to access Grid • Infrastructure • Middleware • Grid Portal • Portal technologies • JSR 168 / WSRP • Web 2.0 applied to portal • Grid portals – a survey • Teragrid portal, Gridsphere, OGCE, … • Demo of current JavaScript CoG Kit based portal • Conclusions and Discussion

  3. Approaches to access Grid • Grid Infrastructure • Condor, PBS, LSF, SGE • Globus, UNICORE, EGEE, Legion • Middleware/Upperware • CoG Kit • Gridway • Gridshell • Grid Portal • Teragrid portal, Gridsphere, OGCE

  4. Portal technologies – JSR168/WSRP • Java Portlet Specification (JSR168) Server Portal Server Portlets Container Login Info Portlet Window FAQ Portlet Fragment Welcome …… • Web Services for Remote Portlets (WSRP)

  5. Portal technologies – Web 2.0 • Web 2.0 technologies applied to web portals • Web 2.0, a buzz word • Asynchronous JavaScript and XML (Ajax) • Representational State Transfer (REST) • Mashup • Atom and RSS

  6. Portal technologies – Web 2.0 • Ajax • XML as data interchange medium • Asynchronous communication with server side • XHTML, CSS, and JavaScript to manipulate and render DOM components • Decrease user waiting time and increase user experience Rendered Web page Web Browser Web page Ajax engine Static pages, CGI, Servlet JS code, CSS, libraries, web resources Web Server

  7. Portal technologies – Web 2.0 • REST/RESTful • Roy Fielding’s doctoral dissertation in 2000 • Resource = functionality + state • Unique addressable through URI for each resource • Stateless protocol, eliminating the use of additional message layer such as XML or session maintaining using cookies • Simplicity is beauty • RSS and Atom • Publish “feed” • Subscribe and read

  8. Portal technologies – Web 2.0 • Mashup • Data from multiple sources • Mingle and combine • Presented in a new perspective Web Client Web Service Site A Site B Site C

  9. Portal technologies – Web 2.0 • Mashup applied to JavaScript Grid Portal • Shows mashup happens both in server side and client side JavaScript API & Portal JavaScript CoG Kit server code Teragrid Host A Teragrid Host B Teragrid REST Info service

  10. Portal technologies – A Comparison • JSR168 Portal • Generate markup segments for each portlet and assembly them into a full page • Info aggregated at server side • Portlets displayed side-by-side • Old technologies and about to outdate • Web 2.0 Portal • Combine raw data from different site/web services • Content aggregation can happen in server side or client side • Could combine data from different source and present in a totally new way • Web 2.0 technologies used to provide better user experience

  11. Grid portals – A Survey • GridSphere (uses Myproxy and CoG Kit) • http://www.gridsphere.org/ • OGCE portlets (uses Myproxy and CoG Kit) • http://www.collab-ogce.org/ • Teragrid user portal • http://www.teragrid.org/ • Provide teragrid related information • GSI-SSH terminal • Use GridSphere for some functionalities like file management • Other portals • Genius, Legion, Pegasus, …

  12. Grid portals – Web 2.0 Grid portal

  13. Conclusions and Discussion • Road to Grid • Abstraction and reuse • More user-friendly and lower barrier • Less user involved setup and configuration • Architecture gets more complicated • Hide more complexity behind the “cloud” • Trends • Service Oriented Architecture (SOA) / Web services • Software As A Service (SAAS) • Web application / Rich Internet Application • Cloud • Discussion?
