C t i• Cost savings • Promote consolidation, standardization,

and reuseand reuse

Role of an Architect in SOA Governance

• Apply standards and policies to actions• Provide visibility

P ib hit t l• Prescribe architectural standards and policies /guide project team selection

• Measure compliance

• Frame architectural fsuccess in terms of

business goals

Agenda



Best Practices for Architects

• Organize around a Reference Architecture• Organize around a Reference Architecture• Use the SOA Roadmap to define boundaries• Establish and communicate architectural standards and

id liguidelines• Establish/participate in processes

• SOA Architecture Management• SOA Project Approval• SOA Alignment• SOA Service Infrastructure Management

Iterate• Monitor and enforce architecture and roadmap boundaries• Measure success• Close the loopClose the loop

The Reference Architecture

• A framework to help guide SOAA framework to help guide SOA implementations• Communicates overarching

architectural concerns• Vision and Roadmap• Vision and Roadmap

• Future vision 2-3 years out• Roadmap defines convergence on

future vision over time• Consistency

• Promotes consistency, best practices, standardization

• Provides a means to measureProvides a means to measure architectural compliance

• Empower• Enable educated architectural decisions

and trade offsand trade-offs• Justify

• Relate functionality back to business benefits

The SOA Roadmap

The SOA Roadmap prioritizes the capabilities needed tothe capabilities needed to support the business, and therefore establishes the architectural boundariesarchitectural boundaries.

Monitor & Enforce Boundaries

• SOA involves wrapping your organization’s functional areas in service• SOA involves wrapping your organization s functional areas in service wrappers.

• Foundational organization and architecture guidelines need to be l t d d il i t d t d l t t dencapsulated and easily communicated to development teams and

monitored in production. • Policies

C l ti h• Common solution approaches• The implications of simple guidelines such as “data is owned by the

Enterprise” are far-reaching, and set the boundaries that smaller sub-t dd i d t ilteams can address in detail.

• Adherence to architectural guidelines must to be monitored. • Deviations from architectural guidelines must be tracked and the reason g

for the deviation must be understood.• Some Centralized group is mandatory.
