Chapter 11: SOA Governance
- SOA governance has clear impact on IT governance of the organisation. IT governance is about managing IT of an individual department and managing IT across departments.
- From implementation perspective SOA governance is a combination of policy, process and metadata of the component
- SOA governance is more about how business units interacts involving SOA services, people in order to achieve business goals.
- IT governance is about building business services where rules and process are correctly implemented; this is more targeted towards the reuse of services organization wide.
- It is hard to convert or codify business requirements into services, and that’s about IT governance is. These requirements are implemented by SOA services. This is a how IT and SOA are related.
- As requirements keep changing, business processes and rules keep on updating, and so the IT governance is. As SOA is an implementation of this IT governance, it has to accommodate all such change i.e. to remain dynamic.
- SOA governance steps – organisation wide
o Setup a board – to verify the business processes are followed correctly
o Setup implementation standards across the board e.g. common technologies
o Setup IT SOA governance Best practices – towards reuse of services across organisation, like service names, impact analysis, remedy action standards
o Monitor the life-cycle services – bread-butter services for organisation, make it fail-safe and performance improvement
- IT of an organisation expects from SOA
o Modular design, standardization of webservice interfaces
o Dependent webservices, reliable access, verification of quality and integrity of service and security
o Track and report on results and service improvement
o Well documented process on how regulations followed by services
- Focus and object of SOA governance is: to identify the services business needs and to conduct predictable and accurate those services. Also to maintain quality of service.
- Without SOA governance, SOA will not be trusted as a business computing model.
