SOA Practitioners Guide

A few early adopters of SOA met last year back (August 2005) and agreed to establish an SOA community. This community was prelaunced at the Global Integration Summit (GIS) with the following proposed objectives.
  • Get agreement on terminology for discussing SOA.
  • Influence and deliver requirements to Standards Organizations and Vendors
  • Provide education and rich understanding:
  • Articulate & Promote Business Value Capture
  • Disseminate Success Stories, Best/Worst Practices
  • Offer templates, tool and methodology to ensure investment success
The same early adopters did publish the SOA Reference Architecture at the same event and continued working on documenting SOA best practice. As the SOA communitly was has not yet been formally launced early SOA adopters agreed to publish these best practices as SOA Practitioners Guides and are also available at my structured blog.

SOA Practitioners Guide (Abstract):

SOA is relatively new, so companies seeking to implement it cannot tap into a wealth of practical expertise. Without a common language and industry vocabulary based on shared experience, SOA may end up adding more custom logic and increased complexity to IT infrastructure, instead of delivering on its promise of intra and inter-enterprise services reuse and process interoperability. To help develop a shared language and collective body of SOA, a group of SOA practitioners created this SOA Practitioners Guide series of documents. In it, these SOA experts describe and document best practices and key learnings relating to SOA, to help other companies address the challenges of SOA. The SOA Practitioners Guide is envisioned as a multi-part colelction of publications that can act as a standard reference encyclopedia for all SOA stageholders.

The guide is available in three parts:

SOA Practitioners Guide Part 1: Why Services-Oriented Architecture? - This guide provides a high-level summary of SOA.

SOA Practitioners Guide Part 2: SOA Reference Architecture - This guide covers the SOA Reference Architecture, which provides a worked design of an enterprise-wide SOA implementation with detailed architecture diagrams, component descriptions, detailed requirements, design patterns, opinions about standards, patterns on regulation compliance, standards templates and potential code assets from members.

SOA Practitioners Guide Part 3: Introduction to Services Lifecycle — This guide introduces the Services Lifecycle and provides a detailed process for services management though the service lifecycle, from inception through to retirement or repurposing of the services. It also contains an appendix that includes organization and governance best practices, templates, comments on key SOA standards, and recommended links for more information.

Key Learnings - Using EDA to implement the core SOA principle of "loose-coupling"!!!

A lot has been said about how SOA and EDA are unique "architecture styles". It seems like only one or the other architectural prin...
