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 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 Web Services What are Web Services? When should you use them?
Described in the OS 2200 modernization white paper: OpenDTP MQseries DTI MSMQI NTSI CITA 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 Native OS 2200 middleware Use native middleware… Remember: SOA and Web Services are NOT synonymous!
The next generation business and systems modeling architecture that integrates business vision and IT execution, to drive organizational agility. Unisys services are based on 3D Blueprinting —BUSINESS STRATEGY MODEL BUSINESS ARCHITECTURE —BUSINESS PROCESS MODEL — APPLICATION MODEL SERVICES-BASED TECHNICAL ARCHITECTURE —INFRASTRUCTURE MODEL Increase Agility by Assessing Impacts and Reacting more quickly to Change Reduce Business Process “Cycle Times” For Competitive Advantage Reduce Cost by Eliminating Application & Infrastructure Redundancy
3D Blueprinting and SOA SOA provides the “Structural Abstraction” that links Business Architectures to traditional IT Architectures (Application & Infrastructure) Business A robust approach to service orientation leverages services at the Process, Application, & Infrastructure tiers Consumer Business Process Architecture Service Architecture Technology Provider Component Architecture 3D 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
