  6. Overview of Web Services

  7. Web Services Definition • Web Services are XML-based standards for deploying highly distributed, componentized applications that transcend server, firewall, and enterprise boundaries.

  8. Web Services Characteristics • Platform Independent • Standards-based • Secure • Reusable • Distributed • Scalable

  9. Web ServicesA new paradigm • Service Oriented Architectures consist of: • Distributed & process centric application deployment • Loosely coupled (XML based) interfaces • Publish and discovery capabilities • Web Services are a set of standards that define how to achieve a loosely coupled framework for communication and application development and deployment • In that regard, Web Services are a standards based instance of a Service Oriented Architecture • Web Services allow business processes to be abstracted into ‘services’ that can then be easily linked together

  10. Web Services Dissected • Simple Web Services – Component level building blocks for constructing highly distributed, network based applications. Can be constructed either at design-time (per traditional application development paradigm), or at run-time (concept of the “virtual application”). • Collaborative Web Services – Complex protocols governing the interaction between applications and enterprises. Address additional requirements for security, non-repudiation, business process management, and long-running transactions.

  11. Simple Web Services

  13. Simple Web Services • WSDL (Web Services Description Language) • SOAP (Simple Object Access Protocol) • UDDI (Universal Description, Discovery, and Integration)

  14. WSDL • WSDL • WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. • A Web Service represents a unit of business, application, or system functionality that can be accessed over the Web. • WSDL describes the interface for a Web Service.

  15. SOAP • SOAP • SOAP is a lightweight protocol for exchange of information in a decentralized, distributed environment. • SOAP messages can call a procedure on a server across a network. • SOAP-compliant procedures can be called from across a network. • Firewall friendly – messages can easily transverse firewalls.

  16. UDDI • UDDI • UDDI is a specification for a Web-based business registry that can be used to describe and discover Web Services. (There are both public and private registries.) • WSDL documents (or links to WSDL documents) are posted to a UDDI repository. • A UDDI repository can be searched for exposed Web Services at design-time and run-time.

  17. Now What? • WSDL defines the interface • SOAP defines the messaging service • UDDI defines the repository • Need to orchestrate interaction between Web Services to create an application • Enter WSFL (Web Services Flow Language) and XLANG

  18. WSFL & XLANG • WSFL • Designed by IBM • XML language for the description of Web Services compositions as part of a business process definition • XLANG • Designed by Microsoft • Provides the model of an orchestration of services as well as collaboration contracts between orchestrations

  19. Which Orchestration Spec Will Become Standard? • Not clear whether XLANG or WSFL will dominate • Potential for new XLANG/WSFL hybrid backed by IBM and Microsoft • New standards emerging such as WSCI • Can’t predict future at this point

  20. Collaborative Web Services

  21. Collaborative Web Services • Collaborative Web Services “live higher on the stack” than simple Web Services. • Can be viewed as B2B integration protocols that are built upon Web Services standards. • Address additional requirements for security, non-repudiation, business process management, and long-running transactions.

  22. ebXML • ebXML • ebXML is a complete B2Bi XML framework that enables business collaboration through the sharing of Web-based business services. • ebXML supports the definition and execution of B2Bi business processes expressed as choreographed sequences of business service exchanges. • ebXML expands upon first generation B2B solutions (such as EDI) by standardizing business process, trading partner profiles & agreements, message transports, and security. • ebXML is payload independent.

  23. Key Areas of ebXML Specification • BPSS (Business Process Specification Schema) • Registry • CPPA (Collaboration Protocol Profile & Agreement) • Message Service

  24. RosettaNet • RosettaNet • RosettaNet specifications allow manufacturers, distributors, resellers, and end-users to leverage the Internet to exchange business documents across the entire supply chain. • The RosettaNet Implementation Framework (RNIF) specification provides XML-based standards for business documents and specifies common business processes between trading partners (known as PIPs). • RosettaNet standardizes both process and data aspects of B2B collaboration. • RNIF 3.0 will incorporate ebXML standards for trading partner management and message transport/security.

  25. Web Services Value Proposition

  26. I.T. Benefits of Web Services • XML standards-based – relatively low cost to develop and deploy • Legacy components can be wrapped instead of re-built • Application components can be “outsourced” • Flexibility in solution architecture • Dynamic application-to-application integration • More rapid application development • Developers can focus on “core” business applications

  27. Business Benefits of Web Services • Opportunity to develop new business relationships • On sell-side – Opportunity to compete and sell into a larger market • On buy-side – Opportunity to identify new vendors and better terms & prices • Faster, more flexible e-business

  28. 2 ERP application searches for vendor Web Services that provides product availability and price info 3 Two product query services are found. Descriptions of these services are returned to the ERP application 1 Manufacturer’s ERP system determines need for 1000 5mm steel ball bearings to fulfill customer order 4 ERP application submits order to vendor with best terms and price Simple Web Services Example UDDI Repository

  29. Complex Web Services Example Companies publish descriptive information about themselves (CPP) and required business process (BPSS) in a repository Design Time ebXML Repository CPP CPP BPSS BPSS Run Time ebXML Repository CPP BPSS Buyer discovers seller, electronically defines partner agreement (CPA) based on buyer’s andseller’s CPP, then initiates BPSScollaboration using ebXML messaging

  30. Future: Adoption and Evolution of Web Services

  31. Adoption of Web Services • Hype around Web Services continuing to grow • Standards expected to evolve and mature over coming years – increased focus on security and transactionality required • Organizations will begin to experiment with Web Services internally at first, then “test the waters” outside the firewall with simple components

  32. Adoption of Web Services (cont’d) • Widespread adoption/implementation of Web Services not anticipated until 2004 and beyond • Early applications likely to support transportation, commodity goods & services, and complex calculations • Potentially as revolutionary as the “web browser”, but adoption will be key measure of success

  33. Sybase Web Services Solutions for Integration

  34.
