The “birth” of Ajax
3/31/05: Google Pioneers Use of Old Microsoft Tools in New Web Programs
“Ajax”“a big step toward the Holy Grail of having the kinds of speed and responsiveness in Web-based programs that's usually associated only with desktop software””

Rich Internet Applications (RIA)
Rich Internet Applications …• Delivered over the Web
– Lower TCO than thick client
• Look, feel and perform like desktop software GUIs– Higher efficiency than html pages– Richer functionality than html pages
• “Best of Both”
• By 2010 60% of new applications will include “Rich Internet Applications” (RIA)

Ajax Architecture Strategies
• Enriched HTML pages– Hardwire
• Communications and data to DOM with procedural JavaScript• Replace with new server generated HTML DOM chunks
– Two Pass Parse and Replace• DHTML replacement of “tags” in HTML page after the first load of the page• JavaScript manipulation of DOM and JS Objects
• Ajax RIAs– Object based JavaScript Applications– Communication with services

Four Quantum States of Ajax• A,J,&,X
– All about communications. Where’s the GUI?
• DHTML Widgets – Enabled with async-communications (maybe)
• Multi-Widget Libraries– Shared underlying services
• Rich Internet Application Frameworks– Common GUI, data, communication framework– Ability to visually author GUIs & more

Erosion of Desktop OS
• Ajax RIA minimizing the differences– Real-time data– Offline apps
• The “good enough” factor
• Firefox and Adobe will continue to press Microsoft to provide parity with its browser
• OpenAjax Alliance driving core standards
