Class overview :

Class goals :

• Design modern Service-Oriented Architectures (SOA)
• Evaluate and analyze your organization to map it as a « set of services »
• Develop logical service model designs using the Service-Oriented Modeling Framework (SOMF)
• Convert logical designs into service contracts that can be implemented in any development environment
• Select the right service technology to support each of the four service-oriented business scenarios
• Orchestrate services to implement interoperable solutions

Content of Service-Oriented Architecture (SOA): A Comprehensive Hands-On Introduction

Overview of SOA

• Integrating business processes with SOA
• Deriving services from the organization’s goals and purpose
• Merging SOA design and project management processes

Architecting Services

Service-Oriented design process

• Progressing from conceptual services to buildable services
• Structuring business requirements into SOA
• Aligning services with the organization

Following an architectural road map

• Working forward to deliver applications
• Recycling backwards to support change

Mapping Services to Your Organization

Discovering conceptual services

• Defining the service domain
• Drilling down into atomic services
• Consolidating into composite services

Refining the conceptual design

• Identifying the underlying resource for the service
• Leveraging legacy assets for inclusion in the SOA
• Selecting cross-boundary services

Modeling Services

Developing logical services

• Integrating consumers
• Exploiting the four composition styles
• Hierarchies
• Star
• Network
• Circular

Achieving effective designs

• Supporting loose coupling
• Handling sequential processing
• Establishing relationships between consumers and services

Addressing the business needs

• Designing for reuse and integration
• Aligning services with the organization to improve responsibility

Factoring in brokers

• Identifying « services for services »
• Leveraging the seven categories of brokers
• Transform
• Filter
• Gateway
• Monitor
• Enricher
• Locator
• Router
• Aggregator

Converting Designs to Specifications

Specifying operations

• Deriving operations from use cases
• Identifying design flaws early to take corrective action

Communicating the specification

• Building on the three principles of contract design
• Expressing the service as a contract

Messaging for interoperability

• Evolving messages from the SOA design
• Formatting the operation’s messages

Finalizing the service design

• Specifying operations and endpoints
• Binding messages to operations

Transitioning from Design to Implementation

Supporting implementation

• Enabling parallel development with contract-first design
• Optimizing infrastructure for SOA scenarios
• Interoperability
• Internal backbone
• Ajax
• Implementing components of the SOA

Building services

• Creating services from the SOA modeling process
• Developing service consumers

Orchestrating services

• Assembling services to deliver new functionality
• Dealing with long running processes

Avoiding Common Problems

Applying « Lessons Learned » to improve designs

• Facilitating asynchronous services
• Dealing with change and growth

Ensuring performance

• « Chatty » vs. « Chunky » messages
• Avoiding the failures of applying object-oriented design to services

Managing the SOA Environment

Instituting governance at run time and design time

• Advancing up the Services Integration Maturity Model
• Leveraging Enterprise Services Buses (ESB)
• Integrating key tools in managing your SOA environment
