Session Objectives : 

Session Objectives Introduce Service-Oriented Architecture (SOA) Review market maturity and industry adoption of SOA Understand the principals and practices behind successful SOA implementations Explore the business innovation focus areas for SOA and understand how to achieve maximum business value

The Business Justification for SOA : 

The Business Justification for SOA Business and IT Alignment Driving IT design decisions from a fundamental understanding of the business model to which IT is being applied Business Flexibility Ability to accelerate change Ability to deliver innovative new business functions/capabilities Ability to shift IT spend toward new function => reduce costs

Defining the capabilities for your SOA environment SOA Reference Model : 

Defining the capabilities for your SOA environment SOA Reference Model Business Services Supports enterprise business process and goals through businesses functional service Enterprise Service Bus 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 DevelopmentServices Integrated environment for design and creation of solution assets 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 Management Services Manage and secure services, applications & resources Infrastructure Services Optimizes throughput, availability and utilization Apps & Info Assets

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 Eco-System Governance Content Standards What do we mean by an SOA Foundation?

Core Principles of an SOA Foundation : 

Core Principles of an SOA Foundation SOA style of Enterprise Architecture Loosely-coupled Strongly-coherent Heterogeneous Legacy enablement Holistic Evolutionary Flexible Governed

SOA Lifecycle : 

SOA Lifecycle Gather requirements Model & Simulate Design Discover Construct & Test Compose Integrate people Integrate processes Manage and integrate information Manage applications & services Manage identity & compliance Monitor business metrics Financial transparency Business/IT alignment Process control

Three key sources of services for SOA : 

Consume external services Create new services from scratch Service-enable existing assets Service-enable high-value existing IT assets for reuse Use externally provide services to support commodity tasks Fill in gaps by creating new services Three key sources of services for SOA

SOA Programming Model : 

SOA Programming Model Design Focus on business design modeling, simplification, and role-based collaboration Use of declarative policy …. User Interaction Dynamic support for people integration into the business design Business Components Composable and reusable service implementations Information Built-in access to service state, disconnected service-data exchange, information composition and transformation Composition of Business-level Applications Wired assembly of services to form business-level applications, workflows, and business orchestration 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

Application of the SOA Programming Model : 

Application of the 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 language-independent representation of a data entity that can be passed between services Service Bus A technology- and protocol-independent representation of the interconnection between services Portlets Query CommunityManager

Composite Service Assembly : 

Composite Service Assembly Model for assembling tightly coupled code (Modules) Model for assembling loosely coupled services (Systems) Module Module Web Service

Service Component Architecture (SCA)Implementation :

SOA Governance : 

SOA Governance Business Governance SOA Governance IT Governance SOA Governance is a catalyst for aligning business value from IT governance

SOA governance effectively manages the service lifecycle by governing key processes across the entire lifecycle : 

SOA governance effectively manages the service lifecycle by governing key processes across the entire lifecycle

Business Innovation Focus Areas for SOA : 

Business Innovation Focus Areas for SOA BPM with SOA SOA Maturity Business Agility Service-Enabled IT Assets Composite Business Applications Dynamic Business Ecosystems Semantic Interoperability Enterprise Service Bus Service Registry & Repository Legacy Service Enablers Business Service Lifecycle Management Business Process Management Consumability & Governance

The 5 Facets of Business Process Management (BPM) : 

Business Process Management Rules & Process Execution Modeling & Simulation Content Centric Processing Pre-built industry accelerators Business Activity Monitoring Design and simulate business processes Orchestrate processes across applications and systems Manage processes where content is used as input for a decision or produced as the output Accelerate delivery of composite applications using process, services, and data assets Track performance, processes and operational activity using key performance indicators The 5 Facets of Business Process Management (BPM)

Anatomy of a Business Service : 

Anatomy of a Business Service Operational Capabilities Credit Lookup: 3rd Party Service Credit Eligibility: Legacy System Customer Profile: Packaged CRM Customer Notification: Custom J2EE Web Portal Communication Channels IVR CRM Role-Based Users CSR Consumers Pre-Approval Policies Risk Assessment Policies Business Policies WS-I for service interfaces MISMO, IFW for messages and transactions Technical and industry standards Example: "Credit Check" Business Service Business Services are business level "building blocks" whose execution can be adapted at runtime based on business policy and user context.

Information Modeling and Business Semantics : 

Information Modeling and Business Semantics Data Model Message Model Service Model Process Model Operational Model Semantic Model Classification and Business Dictionary Policies and Constraints Service Relationships Insufficient for ensuring the integrity of service composition

Industry Content for BPM : 

Business Process Business Service Reference Business Service Template Operational Capabilities Industry Content for BPM Accelerate initial Business Service deployment Accelerate Business Service assembly into industry business processes

Business Services Platform: Built for Business Value : 

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

Summary : 

Summary SOA is not just a technology Holistic relationship between Business and IT Enable heterogeneous eco-systems Increased efficiency of technology investments Incremental (“pay as you go”) investment protection Manage risk Focus on value
