What are we trying to achieve?

Reduction!

• Reduction of Complexity• Reduction in Time to Market• Reduction of the Cost of Change• Reduction of Duplicated Effort• Reduction of Information Silos

Promises, Promises…

• Lots of technologies and methodologies have promised to deliver one or all of the “reductions”.

• As a result, standards bodies and professional organizations have been formed to create standards.

Important SOA Standards Bodies

• TOGAF 9 – Architecture Methodology• FEA – Reference Architecture, Complexity

Reduction Techniques• OASIS – SOA Standards, XML Document

Standards• OMG – UML, BPMN, XMI, CORBA• Industry specific standards exist as well

Where to Begin?

• Executive Sponsorship– SOA projects usually cross departments– Gather business requirements

• Select an Architecture Methodology– Zachman, TOGAF, FEA, Gartner– May use components from more than one

Create a Vision

• Agree on business goals and requirements

• Gap analysis• Establish architecture vision• Establish the value proposition• Establish scope

Create the Architectures• Business Architecture

– As Is and To Be with roadmap

• Application Architecture– Identify current systems and create roadmap for target

• Data Architecture– Establish source(s) of truth, replication requirements

• Technical Architecture– Software, hardware and networking

Establish Governance

• Ensures alignment to architecture• Creates a framework for reuse• Manages and enforces run time SLAs• Security policy management &

enforcement• Lifecycle management

No Programs Written, Yet

• By establishing strategy, vision and reference architectures first, a blueprint is created for all implementation project work to use as guidance

• Governance ensures that the architecture is being followed, SLAs are being met, policies enforced and ensures visibility of your enterprise assets

Idea to Action

• Use your roadmap to determine the pilot project

• Use your swim lanes to identify integration points, services, applications and systems involved

Create Swim Lanes for Business Processes

Detailed Business Processes

• Create detailed business processes• Identify gaps (automation required,

business process change, compliance risks)

• Identify existing interfaces• Indentify new interfaces

Midlevel Web Services Breakdown• Identify existing and “to be” web services• Cross-reference with swim lanes/business processes

Canonical Analysis and Creation• Canonicals are simply model documents like invoices

and purchase orders that contain all possible fields that could appear.

• Universal Business Language (UBL) can be used as a starting point (OASIS)

• Oracle AIA Foundation Pack has 140+• EDI Documents can be used as a starting point as well• Design others as needed

Enterprise Service Design

• Use the reference architecture, canonicals and identified web services as the basis for the design.

• There are several types and “layers” of services

• Create the service contracts

Reporting, Monitoring and Security

• All SOA-related reporting and monitoring should be identified and specified

• Should include business and technical control panel

• Security roles and users should be established

Detailed Design• Intended for technical audience implementing

specifications• Includes all services and XML documents• Product-specific modifications also identified, if needed• Security and monitoring policies specified as well• Will need to be reviewed for compliance with reference

architectures

Implement!

• Need promotion policies in place, usually different from existing non-SOA promotions.

• Load testing is important, use the initial load as a stress test, if possible
