© Copyright IONA Technologies 2002 Where to Start with WSI? Contents: Before Where, a bit of Why? Where in terms of Scope? Where on the Network? Q & A Part 1

© Copyright IONA Technologies 2002 Before Where, a bit of Why? If  EVERY major vendor is betting on web services  and  EVERY major application (ERP, DB, app server, mail and messaging, desktop GUI, OS, programming language, etc.) is being retooled for web services  then  The implications are (choose one):  Enormous  Significant  So So  Trivial

© Copyright IONA Technologies 2002 But also Why Not! Security Issues Lack of mature authentication and permissioning Still evolving standards Semantic and Namespace Issues Dynamic marketplaces and relationships are still a LONG way away. Novelty New technology Questions of scalability, robustness, IP, etc.

© Copyright IONA Technologies 2002 A Matter of Costs and Benefits Web Services are not the “be all” and “end all” of integration and communications. They are, however, a very important new technology which is clearly going to transform Enterprise IT. The key is timing, and deciding “Where to Start”.

© Copyright IONA Technologies 2002 The “Grand Vision” is wrong Like almost all technologies, WS in the enterprise will roll from the inside out: Experimentation on the intranet Tentative work with trusted partners on the extranet Eventual use on the public internet Different industries already at different stages

© Copyright IONA Technologies 2002 Where on the Network? Within the Enterprise: –Tentative steps, learning by doing –Eventual fundamental gains Within the Enterprise Private and Trusted Network Public Networks - The Internet Trusted Networks –Emergence of shared semantics –Shared understanding of what works and how things “should” be done Public Networks –Apart from “proof of concept” still a long way away in most sectors –Eventually, an immensely rich resource
