Microsoft and Open Source: Mixed Messages

The increased competition resultingfrom the proliferation of OSS hasbeen constructive for the industry asa whole (MSDN).

Linux is a cancer that attaches itself

in an intellectual property sense toeverything it touches (Steve Balmer)


6/19

The Open Source .NET Equation

Supported By Microsoft?NO WAY, NO HOW!NO WAY, NO HOW!

However, over 400 developershave delivered an independentopen source implementation of.NET.

Mono currently supports 90%+ of.NET Framework 2.0 APIs.

Novell and Microsoft:A Match Made In Heaven Or Hell?

1.

Sales Collaboration: 5 year deal whereinMicrosoft resells SUSE Enterprise Linux

2. Technology Interoperability Collaboration

1. Virtualization interoperability

2. Document format interoperability

3. Mixed environment management interoperability

3. Intellectual Property Agreement: NeitherMicrosoft or Novell will sue each otherscustomers over IP infringement issues.

The Open Source J ava Equation

Sun has recently open sourced mostof the core J DK and virtual machine.

Apaches Project Harmony is wellunder way to provide a trulyindependent implementation.

Sun retains control over the J avatrademark and compatibility test kits.


10/19

Are 64-Bit Applications In Your Future?

Both J ava and .NET Support 64-bit OSArchitectures Today.

Real world feedback shows typically 5% orless performance improvement for todaysapplications running under a 64-bit runtime.

However 64-bit provides access to muchlarger memory addresses (16 TB vs. 4G)

64-bit provides a more efficient runtimeengine for computationally intensiveapplications.

64-bit can provide a mechanism for nextgeneration application designs.

Summary Trends For J ava

J ava technology commitments becomeslightly more vendor proprietary over thenext 3 years but openness continues todrive overall adoption

This is mitigated somewhat by investmentsin open source tools and frameworks.

J ava productivity increases as a result ofless flexibility and simplified J ava EE 5 but

continues to lag .NET for small andmedium scope projects.

J ava adds multi-language capabilities as itexpands to support dynamic languages tobetter address next generation ADconcepts.


19/19

Summary Trends For Microsoft .NET

.NET takes an increasing role insystematic enterprisedevelopment efforts.

Microsofts Team Server tools takea dominant role in .NETapplication lifecycle managementroles.

.NET 3.0 emerges as strongtechnology advances but is slowto be adopted until Vista reachescritical mass adoption.
