The CentraSite Community: The CentraSite Community: Document Transcript

  • The CentraSite Community: Fast-tracking SOA Governance using best-of-breed solutions Gerd Schneider VP Ecosystem Development, Software AG Justin Vaughan-Brown Director CentraSite Community, Software AG White Paper September 2008
  • A modular and integrated approach delivering real-world answers to SOA complexities. ExECutiVE SummAry this white paper is part of a collection of documents about SOA Governance provided by Software AG. it highlights the complexity in creating an SOA, the reasons for this and some of the best practices to help you begin governing your SOA. the major focus of this particular white paper is on the technology tools that can help support your SOA Governance initiative. in keeping with many analyst perspectives, it recognizes that no one single vendor can provide leading-class solutions in every SOA Governance-related area, such as Enterprise Architecture, SOA testing and SOA management. What should be at the heart of your governance tools is a central registry/ repository that can store details of all services, their lifecycle stage and all interdependencies to assess the full impact of this upon other related services can be known. the registry/repository needs to be open, open in the sense that it can integrate with complementary areas of SOA to provide end-to-end lifecycle governance, from initial modeling of business processes, to building in quality at every stage of a service through to understanding how a service is performing once deployed. this white paper illustrates how real-world answers to SOA complexities can be achieved with integrated best-of-breed solutions using CentraSite, the market leading registry/repository. Details of real-world integrations are provided, this includes the numerous benefits achievable when using an open standards-based approach. unlike most white papers, this will be updated periodically with additional integration examples as well as introductions and discussions of other areas related to SOA Governance.
