4. Portal technologies – JSR168 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu4 Java Portlet Specification (JSR168) Portlets Container Portlets Container Login Info FAQ Welcome Server Portlet Window Portlet Fragment Portal Server

5. Portal technologies – Web 2.0 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu5 Web 2.0 technologies applied to web portals - Web 2.0, a buzz word. “Web as platform”? - Asynchronous JavaScript and XML (Ajax) - Representational State Transfer (REST) - Mashup - Atom and RSS

6. Portal technologies – Web 2.0 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu6 …… 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 Static pages, CGI, Servlet Web page Web Browser Web Server Ajax engine JS code, CSS, libraries, web resources Rendered Web page

7. Portal technologies – Web 2.0 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu7 REST/RESTful web service - Roy Fielding’s doctoral dissertation in 2000 - Resource = functionality + state - Unique addressable through URI for each resource - Use HTTP verbs such as GET, POST to do the CRUD operations (Create, Read, Update, Delete) - Eliminating the use of additional message layer such as SOAP or session maintaining cookies - Simplicity is beauty RSS and Atom - Web content publishing - Publish “feed”; Subscribe and read - Aggregating

8. Portal technologies – Web 2.0 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu8 Mashup - Data from multiple sources - Mingle and combine - Presented in a new perspective Site A Site B Site C Web Service Web Client

9. Portal technologies – Web 2.0 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu9 Mashup applied to JavaScript Grid Portal - Shows mashup happens both in server side and client side Teragrid Host A Teragrid Host B Teragrid REST Info service JavaScript CoG Kit service JavaScript API & Portal

10. Portal approaches – a comparison JSR168 Portal - Generate markup segments for each portlet and assembly them into a full page - Info aggregated at server side - Portlets displayed separately - Relatively old technology and is to be enhanced by newer standard (JSR286) 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 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu10

11. A Web 2.0 Grid portal and reusable JavaScript CoG Kit 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu11 Multi-tier SOA based framework Grid services are exposed through JavaScript library in client side for those web based Grid application developers A generic purpose Grid portal built upon the JavaScript CoG Kit enable access to Teragrid through web browser

12. System architecture 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu12

13. JavaScript Library enables Grid access 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu13 JavaScript library to consume Java based web services while providing a higher level abstraction for web based Grid application developers JavaDoc style documentation - https://lily01.rit.edu:8443/grid/jscogdoc/jsdoc/index.htmlhttps://lily01.rit.edu:8443/grid/jscogdoc/jsdoc/index.html - Subject to change since it is still under active development Reusable to construct Grid portal or other domain specific scientific gateways upon it

19. Conclusions and Discussion 12/2/2015Service Oriented Cyberinfrastructure Lab, http://grid.rit.edu19 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 Demo: Tuesday 1:30 Indiana, or call 585 298 5285
