Agenda  Meaning of Boundaryless Information Flow  Boundaryless Information Flow Services  Web Services fit

Boundaries Pose Problems…  They hinder interactions between partners  They slow down processes  They help preserve the status quo  They thwart economies of scale

Yet Boundaries are Effective…  They provide privacy and security  They allow efficiencies of locality  They allow competitive differentiation and strategic advantage  They help enforce accountability  They define domains of process integrity

Types of Boundaries…  Infrastructural  Organization of the interconnecting and underlying facilities  Structural  System growth is limited by the “strength” or scalability of its structure  Architectural  Differently architected technologies often don’t “fit” with each other  Semantic  Different ways of representing the same thing

“Boundaryless” Means…  Aligning with boundaries that have value and utility  Structuring IT so it removes unnecessary boundaries  Not creating the new boundaries that hinder progress

“Boundaryless” Means…  Respecting Boundaries that are necessary

“Boundaryless” Means…  Necessary boundaries can be effective yet transparent  Semantic boundaries can be overcome using directories and locator services

What is a WEB Service?  "application components whose functionality and interfaces are exposed to potential users (including computer applications) through the application of existing and emerging Web technology standards..."  Alternate definition from “Security in a Web Service World: A Proposed Architecture and Roadmap”  From IBM and Microsoft Corporations

Some Boundaries Demand Respect…  Bounded domains of authority and accountability  Boundaries of personal “space” and privacy  Economic boundaries of competition  Property rights (real, personal, intellectual)  Physical boundaries of space and time

We Are Looking at…  Security, integrity, discovery  Political and regulatory limits on information flow  Property rights  Information aggregation and disaggregation  portals and beyond  Data into information into knowledge into understanding

What is a WEB Service?  A software application identified by a URI, whose interfaces and binding are capable of being defined, described and discovered by XML artifacts and supports direct interactions with other software applications using XML based messages via internet-based protocols Source: W3C Web Services Architecture Working Group
