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

Portal Server
• Web Services for Remote Portlets (WSRP)
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
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

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
Portal technologies – Web 2.0
• Mashup- Data from multiple sources- Mingle and combine- Presented in a new perspective

Portal technologies – Web 2.0
• Mashup applied to JavaScript Grid Portal- Shows mashup happens both in server side and client side

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
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, …
Grid portals – Web 2.0 Grid portal
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?
