Web Services What are Web Services? • Standardized way to implement SOA over the Internet (or any network) • Based on XML files and messages – WSDL (Web Service Description Language) to describe services – SOAP (Simple Object Access Protocol) to format messages – Dozens of other standards at varying levels of maturity When should you use them? • When you want the highest degree of standardization, platform independence, and future flexibility • When functionality is needed by business partners, clients, and suppliers who operate in a wide variety of computing environments • When you have technology that supports them, such as the Java EE environment on OS 2200 21

Native OS 2200 middleware • Described in the OS 2200 modernization white paper: – – – Open. DTP MQseries DTI MSMQI NTSI CITA Remember: SOA and Web Services are NOT synonymous! Use native middleware… • When you have no need to extend the services outside the data center and your internal, active networks • When you have real-time performance needs that cannot be met in a Web Service environment • When you have specific platform and technology integration needs • When you do not have Java expertise but do have expertise in direct use of these middleware solutions • When you are using distributed transactions that span services 22

SOA-enabling Unisys Professional Services Page 23

Unisys services are based on 3 D Blueprinting The next generation business and systems modeling architecture that integrates business vision and IT execution, to drive organizational agility. BUSINESS ARCHITECTURE SERVICES-BASED TECHNICAL ARCHITECTURE Increase Agility by Assessing Impacts and Reacting more quickly to Change — BUSINESS STRATEGY MODEL — BUSINESS PROCESS MODEL — APPLICATION MODEL — INFRASTRUCTURE MODEL Reduce Business Process “Cycle Times” For Competitive Advantage Reduce Cost by Eliminating Application & Infrastructure Redundancy 24

3 D Blueprinting and SOA approach to service orientation leverages services at the Process, Application, & Infrastructure tiers Business Process Architecture Service Architecture Technology Provider A robust Consumer SOA provides the “Structural Abstraction” that links Business Architectures to traditional IT Architectures (Application & Infrastructure) Component Architecture 3 D Blueprinting provides methods and frameworks to structure “services” at the Business Process layer, Application Layer, and Infrastructure layer, providing a robust and “aligned” SOA implementation across an implementation 25
