Slide 1: The Road To Service Oriented Architecture Eric Schmidt Technical Evangelist Platform Strategy and Partner Group Microsoft Corporation
Slide 3: Agenda Service Orientation Web Services Architecture Technology Roadmap
Slide 4: Connected Systems Everything Connected Service Oriented Architecture Web Services Architecture Application Archetypes
Slide 5: Shift To Service Orientation From Connections = cost Function oriented Build to last Prolonged development To Connections = value Process oriented Build for change Incrementally deployed Application silos Tightly coupled Object oriented Orchestrated solutions Loosely coupled Message oriented
Slide 6: Service Orientation A service oriented architecture (SOA) significantly elevates the abstraction level for code re-use It allows applications to bind to services that evolve and improve over time without requiring modification to the applications that consume them Evolution not revolution
Slide 7: Service Orientation Core Tenets Explicit Boundaries Autonomous Negotiation Via Policy Exposed Schema and Contract Message Driven Reuse & Dynamic Meaningful Information
Slide 8: Service Orientation Key Concepts Operational Requirements enforce Policies governed by bound by Message Exchange Pattern Contracts describe is a set of Schemas define structure of Applications State composed of manage Services exchange Messages have contain
Slide 9: Service Orientation Basic Consumer/Provider view Service Consumer Service Provider Business Component Service Façade
Slide 10: Service Orientation Required Capabilities Security Reliability Transactions Discovery Management Transport independence Interoperability Process orchestration
Slide 11: Service Orientation Business Process View Coarse Grained Web Service Operations Finer Grained Internal Service Operations Fine Grained Object and database calls Business Component Business Component Consumer Application Business Process
Slide 12: Why This Is Important To You… How do you extract and leverage value from? Connectivity Decomposition Business process aware Resilient to change Continuous improvement Reuse
Slide 13: Unified Connectivity Less overhead, reduced surface area Consistent programming model Native interoperability EJB MQ DCOM ODBC Your Application
Slide 14: Abstraction Enables you to more gracefully decompose your application Enables you to extend and optimize your processes Business Processes Business Process Business Processes Your Application
Slide 15: Dynamic Discovery enables you to add services and consume services at “run-time” Policy enables services to dynamically calibrate and optimize overtime Guaranteed Delivery PKI Windows Credentials Guaranteed Delivery Windows Credentials Custom Credentials
Slide 16: Resilient Schema provides a mechanism to decouple database, programming and “wire” format – this makes your application more resilient to change Coarse grain messaging enables loose coupling Business Process <ORDER>…..</ORDER> <ITEMS>…..</ITEMS> 1 Shoes 12.99
Slide 17: Reuse Decomposition promotes reuse and enables more dynamic business processes Requires you to embrace a business process model 000197 TBLEDIT SECTION. 000198****************************** 000199* 000200 DISPLAY ROOM-TOTAL-NUM(TBL-IDX). 000201 DISPLAY TBL-IDX. 000202 MOVE ROOM-TOTAL-NUM(TBL-IDX) TO WK-ALL. 000203 MOVE ROOM-RSV-NUM(TBL-IDX) TO WK-RSV. 000204 PERFORM RITU-COMP. 000205 MOVE WK-ALL TO POW-0001. 000205 MOVE TBL-IDX TO POW-0002. 000205 MOVE 1 TO POW-0003. 000205 CALL "_XPOWTABLESETNUMERICTO" USING BY VALUE ROOMTBL 000205 BY REFERENCE POW-0001 BY VALUE POW-0002 POW-0003 . 3.3.

Slide 18: Foundation For Smart, Visible Office BI Services Processes  Schema enables your services to become more strongly typed to business process  Decomposition provides more discrete access to business visibility (Milestones)  Information access drives smart processes Business Process Real-time collection of activities Real-time Monitoring Business Process Activity Tracking
Slide 19: Security, Reliability, Transactions The message dictates capabilities and behavior Efficiently cross boundaries Stand on the shoulders of the architecture and the plumbing You can focus on building applications not the infrastructure
Slide 20: Service Oriented Systems Business Impact ISV Impact Deployment and integration efficiency Flexibility, extensibility and reuse Broad new opportunities Customer Impact New access to knowledge assets Agility to react to business change Solution flexibility
Slide 21: WRQ (Verastream) The emergence of Web services and Service Oriented Architectures has invigorated a market for integration of legacy platforms… many companies now feel that they can take an incremental approach to integrating with their legacy infrastructure and don't have implement a large, complex integration project.  This has been good for WRQ because customers have found Verastream to be the right tool to abstract their legacy applications into a series of reusable services that fit nicely into their Service-Oriented architectures.
