SOA governance [ edit ]
SOA governance (Service-Oriented Architecture (SOA)refers to a service-oriented architecture to execute control service related activities. SOA governance can be seen asa subsetof information technology governance , and information technology governance isa subsetof corporate governance . SOA governance focuses on how to use resources to bring value to the enterprise. SOA requires many IT support processes and many organizational processes that involve business leaders. Service-oriented architecture requires a solid foundation based on standards, including strategies, contracts, and service level agreements. By using services, companies want to be able to quickly build and change organizational business processes. To achieve agility, there needs to be coarse-grained and fine-grained services that can be used. Therefore, a service-oriented architecture has increased the demand for good governance. Good governance will help allocate decision-making power, roles and responsibilities, and focus attention on the organizational capabilities needed to achieve success.

Definition [ edit ]
The different definitions of SOA governance are the same in that the purpose of SOA governance is to implement controls. The difference lies in the responsibilities that SOA governance should have. Some narrow definitions focus on implementing strategies and monitoring services, while others use a broader business-oriented perspective.
Anne Thomas Manes defines governance as “the process that an organization implements to ensure that things are done correctly, that is, to follow best practices, architectural principles, governance regulations, laws, and other determinants. SOA governance is the process used to manage the adoption and implementation of architecture-oriented services." [1]
The unique focus of SOA governance lies in the development of services that add value to the business. Effective SOA governance must include the people, processes, and technologies involved in the entire SOA lifecycle from a business perspective, and it must include connectivity and reuse from an information technology perspective. In order to use information technology to adjust business.
Again quotes Anne Thomas Maynes: “Service-oriented architecture is about behavior, not what you build and buy. You need to change your behavior to make it work.” [2]
Gartner defines SOA governance as "ensure that the assets and work products in the architecture work as expected and maintain a certain level of quality." [3]
ISO 38500 describes a framework that includes six guidelines for organizational governance of information technology and models for managers to govern information technology. The main tasks of governing information technology are: (evaluation, guidance, and monitoring. ISO 38500 distinguishes between "governance", "management" and "monitoring".
Scope of SOA Governance [ edit ]
Some typical governance issues that may arise in service-oriented architecture are:
- Providing value for stakeholders : Investment will bring benefits to shareholders, and service-oriented architecture is the same.
- Compliance with standards and laws : IT systems need to undergo audits to demonstrate compliance with Sarbanes-Oxley- like regulations. In service-oriented architecture, the behavior of the service is usually unknown.
- Change Management : Changing a service often has unforeseen consequences because the service provider does not have information about the service consumer. This makes analysis of the impact of change services extremely difficult.
- Guarantee the quality of the service : Because adding new services in the service-oriented architecture is very flexible, special attention needs to be paid to the quality of these services, including design quality and quality of service ( QoS ). A service usually invokes other services. The failure of such a service can cause failures in many applications.
Key activities mentioned as part of SOA governance include:
- Inventory of management services: Planning for the development of new services and updates of existing services
- Manage service lifecycle: The need to ensure that service updates do not disrupt current service consumers.
- Use policies to limit behavior: To ensure the consistency of services, you can create rules that apply to all services.
- Monitor the performance of the service: Due to the combination of services, the consequences of service downtime or inefficiencies can be severe. Therefore, it is necessary to monitor the performance and availability of the service and respond to it in a timely manner if there is a problem.
