Service Oriented Architecture (SOA) coupled with Enterprise Architecture Frameworks provided the much needed discipline in the IT lifecycle. SOA Governance provides an effective control framework along the people, process and technology dimensions to successfully adopt SOA within an Enterprise. A typical SOA lifecycle has the following phases :
- Master data management/data services
- Enterprise business process and domain consolidation and normalization
- SOA governance-plan creation
- Enterprise service bus (ESB) implementation
- SOA product-selection assistance and recommendations
- Business process and SOA alignment
- Real-time SOA monitoring and reporting
- Change management
During each of the phases, SOA governance best practices are critical in successfully managing the SOA processes and infrastructure.
- Service Development
- Service Discovery
- Service Deployment
- Service Execution
Service Discovery: It is very important to locate a service for reuse rather than building from scratch. The service repository helps you locate the service. Service discovery also enables in creating a composite service by discovering and combining two or more services. Service Deployment:The service descriptions created during the service development stage should be published to the service repository. The promise of SOA is achieved through the reuse and effective governance review and processes ensure that the development teams publish the descriptions before deploying the service. Service Execution: To achieve location transparency the right service endpoint and interface information needs to be accessed. This is achieved through the use of service registry. It is important to capture the right service metrics so as to monitor the service usage effectively. There are products today available in the market that accelerates service registry and repository.
Beside the process and technology aspects having the right people organization (roles and responsibilities) is critical to successful SOA governance. An executive sponsorship and the ability (and willingness) of various teams to come together and define a joint strategy/roadmap/architecture are the foundations to effectively adopt SOA.
- Service Development: The developer community needs to adopt the contract first development methodology while developing a service. This ensures that the right metadata is identified. The metadata includes service descriptions, taxonomies, XML Schemas and other service metadata artifacts.
