Business Drivers




Data Availability
Timeliness of Data
Data Manipulation
Dispersal to Clients
Current Environment

The bulk of applications are based on the
client server model
 Developers have a rich, mature toolset for
building client server applications.




High Level Language – Visual Basic
Integrated Dev Environment – Visual Studio
Drag and Drop Functionality
Intelli-sense
Client Server Disadvantages

Complicated deployment
 Difficult maintenance
 Limited accessibility
 Bandwidth issues
 Higher Support Costs
Web-Based Model

Web based model is simpler
 Easier deployment
 Easier maintenance
 Improved accessibility
 Reduced Bandwidth
Disadvantage of Web Platform

Tools not as mature as for client/server
– Few developer controls
– Development environment not well integrated
– Weak error handling
– Problematic MTS component deployment
– Others
Why .NET
ASP.NET and Visual Studio.NET
addresses the shortcomings of current web
application tools and greatly improves
developer productivity.
What is .NET?
It all started in 1997…
 Admin of DLLs, COM, COM+, DCOM
resource intensive
 Needed a “clean sheet”
 Change your way of thinking
 Scale Horizontally not Vertically

– Provides fail-over and easy incremental increases
Goals of .NET

Simplified development with unified
programming models
 Robust foundation with secure execution
environment
 Simplified application deployment and
management
– Eliminate DLL Hell via XCOPY deployment
What is .NET?
How .NET Helps
“Making the common things simple and
the complex things possible”






Easy programming model – Visual Basic
Integrated Dev Environment – Visual Studio
Rich Class Framework – objects for everything
Compiled Execution - speed
Drag and Drop Functionality
Intelli-sense
How .NET Helps

Simple deployment
 Increased developer productivity
 More projects completed in less time
 Current Staff Retention
 Deferred Staff Increase
Transition to .NET

Business driven – project by project basis
– First target small projects with easy fallback

Focused training for developers who will use it in
the short term
– Self taught is possible but takes a lot longer

Leverage industry resources
– Mentors, User Groups, Forums, etc.
Impact on Environment

ASP.NET can co-exist with traditional ASP,
avoiding forced mass migrations.
 ASP.NET can be implemented with minimal
organizational impact.
– Install framework on just one web server
– Install Visual Studio.NET for one developer

Summary

The Client Server model has great tools but
has some drawbacks.
 The Web model addresses these drawbacks
but has mediocre tools.
 The ASP.NET web model address these
drawbacks and has great tools.
Analyst Perspective on .NET
“.NET is a brilliant strategy that enables Microsoft to define the next shift in
the software business.”
Gartner Group
“Everyone should build on the XML/SOAP
foundation.”
Meta Group
“Gartner believes Microsoft is now
providing more vision and influence
regarding this shift than any other
vendor.”
Gartner Group
“.NET is a leading example of what we
believe will be the dominant architectural
model for the next generation of Internet
applications.”
Patricia Seybold Group
Summary
(continued)

ASP.NET is low risk
– Small projects now, bigger ones later
– No forced mass migration

.NET framework eliminates DLL Hell
– Support cost$ will be reduced
Recommendation
 Embrace
limited .NET deployment
(Full deployment later)
 New Web
development should be done
under ASP.NET & Visual Studio.NET
This gives us the best of all worlds!
