SOA - Services
• Self-contained units of functionality
• Reusable
• Stateless
• Loose coupling
• Interoperable
• Discoverable
• Orchestration
Services in the Wild

Services exposed (or exposable)
• Systems and web applications already expose oodles of lightweight services
• You can easily make them expose more lightweight services
• Probably more easily than getting the applications to expose formal web services?
• WOA?
RSS

• News sources
• Social networking sites
• Wikis and websites
• Change logs

Enterprise Portals
Enterprise Portals
• Aggregate Content & Applications
• Customization & Personalization
• Access Control
• Consistent User Experience
Enterprise portals support:
Aggregation
• View or path to everything in the Enterprise (content, applications, services) – Simple deep links to websites
– Dashboard-style display of services
– Applications running within the portal
• Provides user with a single centralized place to start
• Entry point for single sign-on architecture
Aggregation
Aggregation
Personalization
• User needs vary within an Enterprise
• The more that is understood about a user the greater the ability of the portal to display services and content most relevant to that user. – Groups
– Roles
– Attributes
• Enables user to customize their view of the portal to suit their own preferences.
– Ability to add/remove elements from the portal layout
– Ability to change how portal elements are organized
– Ability to configure details of individual portal elements
Personalization
Student
Personalization
Faculty
Access Control
• Enterprise portals provide a way to control access to individual elements
• Individual user access based on: – Group
– Role
– Attribute
• Services not accessible for a user are not displayed in the portal for that user
• Access control for accessible elements are managed by the portal
Unauthenticated View
Authenticated View
Delegated Authentication
• CAS Proxy Tickets
• Shibboleth Delegated SAML Assertions

XML / XSLT transformation
• XML
• Transformed via XSLT
• To Markup Presented in Portal

Strategies for Effective SOA
• Re-usable composite service-consuming UIs
• Purpose-built “mashups” of services
• User-facing services
– Self-service widgets
Mashup examples
• Courses on campus map
• Course reserves
User-facing Services via the Enterprise Portal
What about the other ‘Services’
• News and Announcements/Messaging
• Applications/Workflow/Tools
User-Centric, not Developer-Centric
Services users need quickly and frequently
How to expose services
1. JSR168/286 Portlets 2. WebProxy 3. RSS 4. Inline frames 5. SQL Queries 6. SSO 7. Deep Linking (shortcut into apps/content)
JSR168/286 - Portlets
Actual software applications, written in Java. • Provides a standard pattern for developers • Independent of Portal platform • Reusable • Shareable
WebProxy
Portlet retrieves, transforms, and presents any web application you like.*
Web Proxies at Wisconsin
Web Proxy of Conference Website
RSS Reader
Render RSS feeds
RSS Reader
Inline Frames
Sure is easy…
Single Sign On
Via Credential Replay Or via enterprise SSO solutions, like CAS and Shibboleth.
Deep Linking
Portal as discovery layer for the user-facing services proliferated across your campus.
