SOA Manifesto unveiled

SOA Manifesto unveiled

Summary: A working document for the SOA journey ahead.

SHARE:

As mentioned earlier, I had the opportunity to join a group of highly motivated and very smart people at the SOA Symposium in Rotterdam to formulate what is being called the SOA Manifesto. Here is the final version of the document, spelling out the core values and related principles that should be part of service orientation and SOA. Hopefully, they will help guide your thinking on the SOA journey:

SOA Manifesto

Service orientation is a paradigm that frames what you do. Service-oriented architecture (SOA) is a type of architecture that results from applying service orientation.

We have been applying service orientation to help organizations consistently deliver sustainable business value, with increased agility and cost effectiveness, in line with changing business needs.

Through our work we have come to prioritize:

  • Business value over technical strategy
  • Strategic goals over project-specific benefits
  • Intrinsic interoperability over custom integration
  • Shared services over specific-purpose implementations
  • Flexibility over optimization
  • Evolutionary refinement over pursuit of initial perfection

That is, while we value the items on the right, we value the items on the left more.

SOA Manifesto Guiding Principles

We follow these principles:

  • Respect the social and power structure of the organization.
  • Recognize that SOA ultimately demands change on many levels.
  • The scope of SOA adoption can vary. Keep efforts manageable and within meaningful boundaries.
  • Products and standards alone will neither give you SOA nor apply the service orientation paradigm for you.
  • SOA can be realized through a variety of technologies and standards.
  • Establish a uniform set of enterprise standards and policies based on industry, de facto, and community standards.
  • Pursue uniformity on the outside while allowing diversity on the inside.
  • Identify services through collaboration with business and technology stakeholders.
  • Maximize service usage by considering the current and future scope of utilization.
  • Verify that services satisfy business requirements and goals.
  • Evolve services and their organization in response to real use.
  • Separate the different aspects of a system that change at different rates.
  • Reduce implicit dependencies and publish all external dependencies to increase robustness and reduce the impact of change.
  • At every level of abstraction, organize each service around a cohesive and manageable unit of functionality.
