What is SOA Governance?

• Compliance to standards or laws
• Change management
• Ensuring quality of services

• Monitoring performance of services

The SOA Governance issue

• Governance appearing as SOA initiatives
• A dynamic environment for services to interact
• Encouraging the reuse of services
• Controlling how services interact with each other

SOA Governance Stages

• First: Realization that governance is needed
• Second: Governance improving business execution
• Third: Mixing technology & changes in behavior
• Fourth: Technology selection & implementation

Service Management

• Design-time perspective
• Run-time perspective
• Repository of service for reuse
• Services contained in heterogeneous platforms
• Service-virtualization for run-time management of services

Critical governance components

• Service registry service and an asset repository
• Creating a "SOA Centre of Excellence"
• Focusing on establishing SOA organizational guidelines
• The organizational maturity
• Agreed governance policies

SOA Governance tools

• Real time monitoring of events
• Failures in a BSM framework
• Service-level instrumentation
• Hooking into operational management systems
• Virtualization as enabler to separate governance/service logic
• Service virtualization managed by operational staff

Developing core SOA governance

• Why SOA technology stack has grown complex
• Mixing between COTS & in-house
• Justifying external consultants to help out
• Figuring out which business we are really in

Roles and responsibilities involved in SOA Governance

• Establishing a SOA Centre of Excellence
• Enterprise-wide planning and assistance in execution
• The roles of the SOA architect/governance architect
• Solving potential conflicting interests
• Ensure that governance guidelines are followed

Barriers to SOA governance

• Not realizing the need for governance
• Lack of Governance technologies
• Lack of Service virtualizations

State of good governance

• Interaction with external parties
• Managing the business rules and BRE mgmt

• View governance as a moving target
• Manage policies as entities with their own lifecycles
• Choose a technology platform
• The platform should address immediate governance needs
• Future support as SOA infrastructure scales
• Enforce service level agreements
