Flexible business requires flexible IT  Economics: globalization demands greater flexibility  Business processes: daily changes vs. yearly changes  Growth through flexibility is at the top of the CEO agenda  Reusable assets can cut costs by up to 20%  Crucial for flexibility and becoming an On Demand Business Today’s World-Class Business* *Sources: CBDi Traditional Business* 3 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture Business and IT Alignment A transformation across domain views Business View Process View IT View 4 A Framework for Delivering Business Value © 2008 IBM Corporation What is ….. … a service? … service orientation? A repeatable business task – e.g., check customer credit; open new account A way of integrating your business as linked services and the outcomes that they bring … service oriented architecture (SOA)? … a composite application? An IT architectural style that supports service orientation A set of related & integrated services that support a business process built on an SOA © 2008 IBM Corporation 5 SOA Foundation Architecture What do We Mean by an SOA Foundation?  A software and hardware platform for building, deploying and managing solutions that subscribe to the SOA style of enterprise architecture – Along with: – Community – Ecosystem – Governance – Content – Standards 6 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture SOA Use & Adoption: Focus of upcoming activities Infrastructure services focus 55% 41% Internal integration 54% 46% Customer-facing applications 53% 47% Employee-facing applications 51% 43% Extended/integrated business processes 44% 41% Using SOA Considering Legacy modernization 38% 31% Supplier-facing applications 37% 27% © 2006 AMR Research, Inc. 7 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture The SOA Foundation Reference Model Business Services Supports enterprise business process and goals through businesses functional service Interaction Services Enables collaboration between people, processes & information Process Services Orchestrate and automate business processes Information Services Manages diverse data and content in a unified manner Development Services Integrated environment for design and creation of solution assets Management Services Manage and secure services, applications & resources Enterprise Service Bus Partner Services Connect with trading partners Business App Services Build on a robust, scaleable, and secure services environment Access Services Facilitate interactions with existing information and application assets Infrastructure Services Optimizes throughput, availability and utilization 8 A Framework for Delivering Business Value Apps & Info Assets © 2008 IBM Corporation SOA Foundation Architecture Supporting Products WebSphere Business Modeler WebSphere Business Monitor WebSphere Business Svcs Fabric WebSphere Process Server WebSphere Information Server WebSphere Customer Center DB2 Data Warehouse WebSphere Service Registry & Repository Data Power WebSphere Portal Lotus Workplace Collaboration Services Lotus Development Expeditor Business Services WebSphere ESB Interaction Services Process Services Information Services WebSphere Message Broker Services Management WebSphere Services Transformation Enterprise Service Bus Rational Software Architect Rational Application Developer WebSphere Integration Developer Extender Partner Services Business App Services Access Services Apps & Info Assets Tivoli Composite Application Monitor Tivoli Identity Manager Tivoli Federated Identity Manager Infrastructure Services WebSphere Partner Gateway WebSphere Application Server WebSphere Adapters WebSphere Network Deployment WebSphere Extended Deployment Tivoli Access Manager 9 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture Core Principles of an SOA Foundation  SOA style of Enterprise Architecture  Loosely-coupled  Strongly-coherent  Heterogeneous  Legacy enablement  Holistic  Evolutionary  Flexible  Governed 10 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture SOA Lifecycle Discover Construct & Test Compose Integrate people Integrate processes Manage and integrate information Gather requirements Model & Simulate Design Financial transparency Business/IT alignment Process control Manage applications & services Manage identity & compliance Monitor business metrics © 2008 IBM Corporation 11 A Framework for Delivering Business Value SOA Foundation Architecture Three Key Sources of Services for SOA Consume external services Serviceenable existing assets Create new services from scratch 1. Service-enable high-value existing IT assets for reuse 2. Use externally provided services to support commodity tasks 3. Fill in gaps by creating new services 12 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture SOA Programming Model  Service Components – A technology- and language-independent representation of a service which can be composed with other services  Service Data – A technology- and languageindependent representation of a data entity that can be passed between services Portlets Query  Service Bus – A technology- and protocolindependent representation of the interconnection between services Community Manager DB Oracle Adapter SAP Access DB Adapter Access 13 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture SOA Programming Model Aspects  User Interaction – Dynamic support for people integration into the business design Design ( Models, Patterns, Templates, Policy )  Business Components – – Composable and reusable services  Information Built-in access to service state, disconnected service-data exchange, information composition and transformation Wired assembly of services to form businesslevel applications, workflows, and business orchestration User Interaction Invocation Information Composition  Composition of Business-level Applications –  Invocation – Loosely-coupled call-style and event-driven interconnection of services with built-in support for topology transparency, mediation, and brokering featuring standards-based interoperability  Design – – Focus on business design modeling, simplification, and role-based collaboration Use of declarative policy to control execution behavior and relationships Business Components 14 A Framework for Delivering Business Value © 2008 IBM Corporation SOA Foundation Architecture Service Assembly Model Model for assembling

from ISV, Legacy, 3rd Party, or Custom assets  Subscribable: Platform needs to control and manage service entitlements for service subscribers Dynamic: Platform needs to dynamically select and execute services based on context, contract and content Visible: Platform needs to Publishable: Platform must be able to describe CBS via meta-data and publish for discovery, inspection and reuse capture business-level usage data to further optimize and adapt offerings to changing needs Governable: Platform needs to manage and govern services through their lifecycle including change mgmt,
