Vision for Future Global e. Business built on a Service Oriented Architecture

The Dawn of a New Era Built on Service Oriented Architecture

Vision of a Service-Oriented Architecture n n n A place where services are ubiquitous and organically integrated into the way we think and work. A place where both users and providers of information interact through a common focus on services. A world where technology is implemented within industry frameworks that operate on a global scale, enabled by open, interoperable standards.

A Common Web Service Framework Is Essential n n n To provide a sustainable foundation, That will allow end-user companies to achieve the payback they require, To invest widely in the service-oriented architecture.

Achieving Sustainable Business Benefits through a Open Standards for Web Services In this post-dot-com era, end user companies are expecting more liquidity and longevity of their assets. To achieve the ROI, Cost Reduction and Service Expansion benefits expected; the widespread deployment of standards-based Web services is essential.

Fundamental Issues that Must Be Addressed § A common framework for Web service interactions based on open standards must occur. § An agreed set of vocabularies and interactions for specific industries or common functions must be adopted.

Business Benefits for Open Standards

Why do standards matter? ROI for e-commerce n n n Normalizing data, processes and users costs time and money ROI can come from operational savings and outweigh the costs, if those savings are stable and persistent This requires l l Stable versioning Reliable, fixed terms of availability (some protection against withdrawal or embrace-and extend) l INTEROPERABLE standards l CONVERGING standards

What is an Open Standard? An open standard is: n publicly available in stable, persistent versions n developed and approved under a published, transparent process n open to public input: public comments, public archives, no NDAs n subject to explicit, disclosed IPR terms n See the US, EU, WTO governmental & treaty definitions of “standards” Anything else is proprietary:

Delphi Group Research on the Value of Open Software Standards § Greatest benefit to support open standards • • • § Increases the value of existing and future investments in information systems Provides greater software re-usability Enables greater data portability Factors driving participation in standards • • • Vendor neutral environment Access to a community of developers Membership comprised of both end-users and software developers

Open Standards Process: Essential to WS Adoption n n n Enables collaboration Assures fairness Provides for transparency Embraces full participation Ensures a level playing field for all Prevents unfair first-to-market advantage for any one participant Meets government requirements

Standard Adoption n To be successful, a standard must be used n Adoption is most likely when the standard is n l Freely accessible l Meets the needs of a large number of adopters l Flexible enough to change as needs change l Produces consistent results l Checkable for conformance, compatibility l Implemented and thus practically available Sanction and traction both matter

What is UDDI 1. SW companies, standards bodies, and programmers populate the registry with descriptions of different types of services 2. UDDI Business Registry Businesses populate the registry with descriptions of the services they support Business Registrations 3. Service Type Registrations UBR assigns a programmatically unique identifier to each service and business registration 4. Marketplaces, search engines, and business apps query the registry to discover services at other companies 5. Business uses this data to facilitate easier integration with each other over the Web

The Registry Standard for Service Oriented Business Applications n “Universal Description, Discovery and Integration” l l l n UDDI - a specification of l l n n UDDI v 2 OASIS Standard: 2002 UDDI v 3 OASIS Standard: 31 Jan 05 Broad vendor and enterprise adoption APIs for publishing and searching for business services and service descriptions, and subscribing to changes to these A data model with built-in metadata extensibility to characterize business services according to enterprise needs The registry standard for visibility and reuse of SOBA components The registry standard for an adaptive enterprise dynamic discovery and binding to SOBAs The service, service definition and metadata “hub” for SOBAs

Security: function by function n Identity authentication Encryption and protection against interception Control of access and authority

Identity authentication The latest e-business security standards implement the next generation of identity deployment l In the 1990’s, PKI assumed a universal network of official certification authorities l Newer federated / distributed identity models permit identity certification to be decentralized and shared among service providers and existing registrars • SAML • WS-Security • XCBF

Encryption and protection against interception & intrusion n A key problem with encrypted messages travelling over a shared or public network: if you encrypt the wrong bits, it doesn’t arrive, or the recipient can’t process it • DSS n • PKI TC Shared and automated methods for managing security require a shared vocabulary about security weaknesses and risks • AVDL • WAS

Control of access and authority n In transactional information exchanges, you often must apply l l n access lists, directories of recipients, levels of authority, and access policies So that you know who gets what, and who should get it • XACML • SPML

What should your company be doing?

Reducing Risk in new e-business technologies n Avoid reinventing the wheel l n Influence industry direction l n n Stay current with emerging technologies Ensure consideration of own needs Realize impact of interoperability and network effects Reduce development cost & time l l save development on new technologies share cost/time with other participants

What can your company do? n Participate l l Understand the ground rules Contribute actively Or… n Be a good observer In any case… n Make your needs known l n Use cases, functions, platforms, IPR, priorities, availability, tooling Be pragmatic: standardization is a voluntary process
