Governance definitions

A lot of debates about SOA Governance definition…

… but no doubt about the importance of Governance to succeeding with SOA

We take the following definitions of SOA governance:

“The ability to organize, enforce and re-configure service interactions in an SOA”. (Michael Wheaton – Sun)

SOA Governance is a set of roles, policies and procedures that guide the adoption of SOA (Miko Matsumura – Software AG)

Registry/Repository

Useful to: Provide a single system of record where all relevant elements of

your SOA become visible to all interested parties Main features:

Registry • Publish, discover services and related metadata like WSDL, XSD, etc.• Organization management (enterprises, persons, jobs, etc.)• Roles of organizations in relation to services and endpoints• Agreement established between consumers and providers• Publish, discover policies that govern the behavior of users (persons or systems)

that participate in the service lifecycle• Dependencies between services or between services and other SOA assets (BPEL

processes, etc.)• Lifecycle management• Reporting: usage indicators, policy violations, etc.

Repository• Service metadata storage• Versioning• Notification

7

Contract/Agreement Management

Useful to: streamline service consumption

Main features: Service Level Agreement (SLA) negotiation between service

consumer and provider Establishing SLA policies like authentication and QoS Definition of penalties and rewards Contract lifecycle and versioning

8

Policy Management

Useful to: Ensure desirable behavior among SOA participants (people or

systems), all along service lifecycle Support an increasing number of services, service providers and

service consumers Main features:

Policy publication, discovery Support of different kind of policies like conformance policies (WSI

Basic profile), QoS policies (latency, availability, etc.), Security policies (access right, encryption, etc.), etc.

Policy lifecycle and versioning Policy enforcement at design time and runtime (in relation to

runtime management)

9

Runtime Management

Useful to: Have an unified vision of all service runtime environments Significantly increase the adaptability to consumers needs

Main features: Service definition and access point import Service monitoring: availability, latency, consumption, reusability,

etc. SLA and Runtime Policies enforcement Policy violation notification

Solution Targeted Audience

18

Dragon targeted audience

Business Analyst: has a business vision of a specific domain. Defines new business capabilities, objectives, processes and constraints (or rules).

SOA Architect: has a global vision of the entire (or domain specific) service architecture. Assembles services into business processes or composite services.

Service Developer: implements and maintains (updates, fixes...) services based on service definition and business constraints.

Quality Manager: defines and executes service tests based on service definition and business constraints.

Operator: push to production, setup and monitor services.

19

Dragon targeted audience

Service Manager: manages service versions and life cycles (state transitions). Defines service categorization and semantic. Enforces policies and SLA.

Chief Information Officer: monitors SOA indicators (QoS, Service usage/reuse, development time...).

Operation Analyst: creates SLA and other policies based on business constraints and objectives.

SOA Librarian (Administrator): manages governance platform (roles, access rights, service categories, tags, indexation rules, life cycle definitions...).
