Approaches to access Grid

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

• Java Portlet Specification (JSR168)

Portal technologies Web 2.0

• 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

• 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

Portal technologies Web 2.0

• REST/RESTful web service
• Roy Fieldings 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

• 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 service
Teragrid Host A
Teragrid Host B
Teragrid REST Info service

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

11
A Web 2.0 Grid portal and reusable JavaScript CoG
Kit

• 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
13
JavaScript Library enables Grid access

• 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.edu8443/grid/jscogdoc/jsdoc/i
  ndex.html
• Subject to change since it is still under active
  development
• Reusable to construct Grid portal or other
  domain specific scientific gateways upon it

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
