J2EE and .NET: An Objective Comparison

Presentation Goal

Evolve and Define Our Manifesto– We Believe in Choice– We Believe in a Heterogeneous World– We Believe in Competition– We Believe in Open Standards– We Believe in Platform Neutrality– We Believe in the Community Process

Agenda

Evolution– Software Architectures– Component Models

.NET Strategies– Presentation Layer– Co-existance– Domination

Complexity & Abstraction– Today’s Architectural Reality

Coexistence Manifesto

Open Application Server Platform– J2EE– Interoperate, Enhance, Migrate– Make .NET Secure– Keep .NET Departmental– Protect Your Investment

The Productivity Sacrifice

.NET– Internally Proprietary– Externally Open– VS.NET Perceived Productive

J2EE– Internally & Externally Open– Portable– Perceived Complex & Difficult

The Cost Comparison

.NET– Microsoft Controls the Price– Microsoft Are Often Giving It Away – Purchase the OS, Server and Tools From One Vendor

J2EE– At Least 30 Different Vendors– Purchase OS, Server and Tools From Many Vendors– Price Points From Free to Price Competitive to Microsoft and

Beyond

Marketing & The Maturity Paradox .NET

– First Release – 2001– Business Strategy– Massive Platform Marketing Budget

J2EE– First Release – 1998– Community Process– Vendor Brand Marketing

Complexity & Abstraction

Technology Drivers for J2EE and .NET

Internet Is Ubiquitous– All Users, Information, Applications On Internet

Internet Becomes Programmable– Applications Conform to Service-Oriented Architecture

Services are Seamlessly Integrated– To Automate Business Processes

Services Becomes Accessible Ubiquitously– Anytime, Anywhere, Any Device via Portals

Services Use Resources On-Demand– Network, Storage, CPU, OS Resource Virtualized to Grids

Application Servers Should NOT be in O/S– Vendor Competition– O/S and Hardware Independence– Undocumented Features– Back Doors– Patches and Upgrades

Free Reference Architectures Proven Community Design Patterns

Understanding the Comparison:Product Versus Specification

What is 1° of Separation?

Basic .NET Vision:– Tightly Integrate All Fine Grained Components

and Languages at Runtime– Loosely Integrate Heterogeneous Applications

With XML Web Services– Communicate Via XML– Smart Client Not Just Browser to Server– Make MS Pivotal in the Architecture
