Issue: Choosing an Application Platform
 Operating systems are no longer the “application
platform” for modern applications
 Two component models: The Java platform and
Microsoft .NET
 Most large companies will support both – decision
becomes a project, process or functional area focus
 Smaller companies will be driven by solution
providers
 Existing infrastructure and skills should be the
biggest drivers of the decision with an eye to
business benefits – speed, integration and agility

Four Critical Tradeoffs
 Platform choice

Many vs. Windows
 Language choice

Java vs. Many
 ebXML

E-business collaboration standards vs. BizTalk
 Plugability and choice

Best-of-breed vs. Integrated stack

Platform Tradeoffs
 J2EE – Windows, Linux, UNIXes, OS/400, z/OS,
etc…



Deploy new applications on existing infrastructure
Maximize use of existing hardware and OS admin skill
mix
Application QoS differentiation with UNIXes and z/OS
 .NET – Windows



Deploy new applications on newer Intel infrastructure
with Windows 2000 and .NET Server
Focus skills towards Windows platform
Leverage existing infrastructure through web services
 If new applications to be deployed on non-Windows
– use J2EE
Copyright © 2001 D.H. Brown Associates, Inc.
10
Language Tradeoffs
 J2EE – Java



Focus on new OO and component paradigm – leave bad
habits behind
Java skills and/or training required
Application or component should be primarily Java – JNI and
Corba bridges not optimal for performance nor simplicity
 .NET – C#, Visual Basic, C++, COBOL, etc…



Leverage existing programming skills – some retraining is
required for .NET Managed Components
Older code can be ported
Non-OO programmers need OO/component programming
training and discipline for max benefit
 If Java skills are scarce or not readily available – use .NET

Plugability and Choice
 J2EE offers several competing application
frameworks – BEA WL Platform; IBM WebSphere;
JBoss; Oracle 9i; Sun ONE; others…

Some J2EE-based offerings/extensions run on multiple
platforms – e.g., there are other portals available on
WebSphere beyond just IBM’s; Novell’s eXtend; BEA
WL Server is part of Sun ONE via partnership; etc…
 Microsoft offers a highly integrated model – with an
ongoing strategy of including more in the base OS.


Greater seamless integration between offerings
Less choice

Migration and Maturity
 J2EE

Migration





None – requires rewrite
Best for new workloads
Can use web services to incorporate legacy IT assets
Also Corba and JNI bridges
Maturity – a few years
 Some parts new – web services, portal, JCA 1.5
 .NET

Migration





COM/COM+ supported in .NET as non-Managed Object
Requires some rewrite/update to incorporate as Manage Obj.
Risk of migrating procedural “bad habits”
Web services
Maturity – less than 1 year;
 some parts more than 1 Year – ADO, OS, COM+

Performance
 IT should not decide based on “industry”
benchmarks




Current J2EE vs .NET comparisons are embryonic
Not representative of user scenarios
All vendors can claim leadership in some configuration
or against some defined scenario
Architect and developer skills *much* more important
 That being said, .NET appears to have some
potential inherent advantages

Method JIT granularity
 J2EE has advantages of UNIX, AS/400 and S/390
when applicable

Acquisition Costs





J2EE offers the lowest acquisition cost with JBoss on Linux. Sun’s new
LX 50 Intel server with Sun Linux and the Sun ONE J2EE server is
competitive with Microsoft .NET on Dell hardware on a value-offered
basis. Additionally, some midrange Solaris 9 configurations are
competitively priced with Microsoft .NET on a value basis.
Microsoft .NET is a price leader when excluding open source J2EE and
Linux and Sun Linux.
Java servlet platforms can be price competitive with .NET.
The J2EE leaders, BEA WebLogic Server and IBM WebSphere Advanced
Edition, are considerably more expensive than Microsoft .NET on typical
business logic tier midrange four-way systems. However, they offer
greater proven enterprise application server capability and more maturity
than Microsoft .NET Server or Windows 2000 Server with the .NET
platform.
Acquisition prices converge at the higher end (eight-way systems) with
the J2EE and .NET differences less than 10%.

J2EE and Linux
 Most J2EE costs > W2K/COM+ / .NET Server
 J2EE OSes  Solaris, Windows 2K, others
 Linux offers J2EE opportunity


High volume on Intel HW; attractive to developers and
potentially ISVs
J2EE + Linux may be less expensive than .NET Server
(acquisition costs; solution pre-req cost)
 IBM and BEA Strategy; Sun Strategy
 The field is wide open for a significant shift in leadership wrt
component frameworks; Microsoft’s new component model
and licensing may open door even wider
 JBoss – Wildcard which is gaining some traction


JBoss Opportunity
A popular development platform
>150,000 downloads/month
 A leading application server in development

 JBOSS: 42%, BEA 28%, Source: JBoss and Togethersoft

Features done by developers for developers
 Hot deploy of apps/services/server
 Simpler approach to packaging/deployment/compilation
Stability
Free – ISV prereq opportunity, e.g., webMethods
JBoss won “Best App Server” from JavaWorld in

Open Source .NET - Mono
 Is an OSS implementation of the Microsoft .NET
 Common Language Infrastructure (CLI)
 Multi-lingual class library
 C# compiler
 Runtime will support .NET web services
 “Soup” allows for web service creation and
interoperbility
 Long-term project and effects on standardization
 Depends on ubiquity…e.g., does Mono get widely
deployed on Linux or does J2EE win out?

Issues for J2EE Vendors





Improve development environment productivity to be more competitive
with Visual Studio .NET. Specifically, simplify the programming model
where possible.
Improve price competitiveness with Windows 2000 through .NET. JBoss
is not supported by a large vendor. Sun SPARC hardware remains
expensive. BEA WebLogic and WebSphere EJB containers are very
expensive. Sun Linux on its new Intel-based LX 50 is a good start.
With the above issues improved, capture as many new developers as
possible by leveraging Linux and Apache.
Complete the process of incorporating web services into the J2EE
standard and add value by incorporating more of ebXML, particularly the
higher level business collaboration standards.
Develop a strategy to ensure a heterogeneous client tier while simplifying
the programming model – J2ME, J2SE, and embedded Linux efforts are
fragmented and at medium to long term risk due to the added value being
built into .NET at this level.

Issues for Microsoft





Ensure a robust and high-quality .NET Server release while maintaining
the current schedule.
Improve user perception of Microsoft forward compatibility in the future
from .NET V1 to V2+.
Demonstrate large scale, enterprise customer success stories with .NET
on par with high-end UNIX and J2EE.
Either preempt ebXML standards at the higher levels with BizTalk and
new web services standards or embrace ebXML. This must be done and
delivered over the next 12-18 months requiring significant vendor
agreement across complex issues. The new business process and
transaction web services specifications are a step towards a standardized
business collaboration framework.
Ensure both the technical (COM-to-.NET migration) and the license fee
migration from NT and 2000 are as simple as possible and competitive
for value offered against Apache Java and XML and J2EE on Linux.
