Business needs Process-Driven Applications Architectural Perspectives for Real-Time Enterprise • Consolidation • Platform convergence on the web architecture around .NET & J2EE • Heterogeneity • .NET & J2EE have to coexist • Interoperability: • From Web Services to Service Oriented Architecture • the Big “Re-Mix” • Legacy wrapping • CICS, MQ, Tuxedo, J2EE,.NET, EntireX, Orbix and … Web Services • And don’t forget to dance • Choreography, orchestration for Business Process

11. If the questions are : Does freedom matter for the future?Is future a matter of freedom?Is Future a short term issue?Is there a future for legacy depending on proprietary standard? How can a standard be proprietary and insure interoperability between applications?

12. Java or Microsoft ? By 2003, the use of open source software will become a standard part of all organisations utilizing Java, with a high number using the Apache Web servers (60% of active sites) and a significant group using open source Java application servers (14%). [...] Microsoft users will have a slower uptake to open source, though many forms of example code are available Open Standards & Open Source : As the core layer of J2EE becomes increasingly marginalized, the line between open source and «commercial» Java vendors will blur. [...] By 2006/07, the cycle of movement between open source and standards will be common, and 80% of organizations developing with Java will make some use of open source products. Licenses: When software is aquired legal review of contracts and licenses is part of the normal process.This is an expense that must also be incurred with open source. accepting specific types of sources can limit the recuring cost for each new package from a site. Then the answer is:Open Standards & Open Source

13. Open Source is playing a significant role • Market analysts agreed upon: • Open Source components become of common use in business • the boundary between software editors and software integrators is slowly fading. • This adoption of open source software introduces a new type of customer-provider relationship • Open Source platforms are moving toward specific domains

ObjectWeb ’s Mission : To provide a self-sustaining open source alternative to proprietary middleware The Key Question • What is an Open Source ? • Not only a open code base or a free software license • But also a critical mass of developers and a critical mass of users: • A critical mass of developers • They ensure the maintenance and evolution of the software • A critical mass of users • They ensure the market relevance of the software • The corner stone: project sustainability • Broad adoption of the code base is the only guaranty of application independence. • Platform & Network enables broad diffusion • A consortium to ensure this results

25. Europe & Open Source Application Server • 4 December 2002, Luis Leamus • During the next 5-6 years, "open source" versions of standard infrastructure software components (application andintegration servers, database management systems) will gradually gain credibility and market share as viable alternatives to traditional vendor offerings in low-end implementations. The technology and financial drivers behind this trend will take a more persuasive overtone in Europe, where cultural, geopolitical, and governmental factors will steer and catalyze open source adoption. We expect this process to focus initially on the application server market, where high levels of functional standardization (i.e., J2EE) will enable a faster (i.e., 2003/04) penetration of open source alternatives (e.g., JBoss, JOnAS, Zope) to often costly and oversized classic offerings from established vendors. Bottom Line: Organizations should systematically evaluate open source application server alternatives to standard enterprise software products. Users should focus on low-end implementation and carefully assess the hidden support and administration costs behind "free" open source licenses.
