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)

Governance Infrastructure
 The main components of an SOA Governance solution:

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
6
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
7
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)
8
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

Dragon Governance Platform
 Open Source governance solution: LGPL license
 Developed by eBM Websourcing, leader in open source
middleware solution development
 Member of the OW2 consortium
 Based on Web Services standards: includes support for WSDL
(1.1, 2.0), XSD, WS-* (WS-Agreement, WS-Policy, etc.)
 Integrates with different kind of Service Platform: Enterprise
Service Bus (PEtALS ESB), Application Server, etc.
 Integrates with a lots of Database: Oracle, MySQL, HSQLDB, etc.

 Targeted Audience
17
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.
18
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...).
