 RIAs combine some of the best features
from both traditional thin- and thick-clients
 RIAs are enabled by
 Enhancements in browser capabilities
 Better utilization of technologies such as
AJAX and JavaScript
 Rich Internet Applications offer
 Desktop-like UI functionality (e.g., D&D)
 Easy deployment

Why Web 2.0 for the Enterprise?
 Web 2.0 is all about
 Creating new markets
 Lowering competitive barriers
It’s fast becoming a Web 2.0
business world, but innovation
never goes out of style.
 Encouraging creativity to come from anywhere
 Enhancing communications
 Making information more impactful
 What does it means for the
enterprise?
 Greater collaboration and innovation across the value chain
 Increased levels of customer intimacy
 Simplification of complex IT and business infrastructure
 Business model flexibility to capitalize on new market
opportunities
According to Gartner:
By 2008, the majority of
Global 1000 companies will
have adopted several
technology-related aspects of
Web 2.0
Missing out on the nontechnology aspects of Web
2.0 means that many
organizations will also miss
out on some of the positive
business benefits
