Trends in Software and Service Distribution
• Recent trends in software and service
distribution include:
– Pull and push technologies
– Application service providers

5
MIS, Chapter 14
Pull and Push Technologies
• Pull technology
– User states a need before getting information
– Entering a URL in a Web browser to go to a certain
Web site
• Push technology (Webcasting)
– Web server delivers information to users who have
signed up for this service
– Supported by many Web browsers
– Also available from vendors
– Delivers content to users automatically at set intervals
or when a new event occurs

6
MIS, Chapter 14
Pull and Push Technologies (cont’d.)
• Examples of push technology:
– “A newer version of Adobe Flash is available.
Would you like to install it?”

7
MIS, Chapter 14
Application Service Providers
• Application service providers (ASPs)
– Provide access to software or services for a fee
• Software as a service (SaaS), or on-demand
software
– Model for ASPs to deliver software to users for a
fee
– Software might be for temporary or long-term use
– Users don’t need to be concerned with new
software versions and compatibility problems

8
MIS, Chapter 14
Application Service Providers (cont’d.)
• Users can also save all application data on the
ASP’s server
– Software and data are portable
• The SaaS model can take several forms:

– Offering a specific service
– Offering a service in a vertical market

9
MIS, Chapter 14
Application Service Providers (cont’d.)
• Advantages:
– Similar to outsourcing
• Less expensive
• Delivering information more quickly
• Other advantages and disadvantages
• Vendors:

and participate as they do in the real world
• VR technology
– Uses computer-generated, three-dimensional
images to create the illusion of interaction in a
real-world environment

11
MIS, Chapter 14
Virtual Reality (cont’d.)
• VR terms:
