In order to provide appropriate context for the concepts and techniques that can help you implement appropriate SOA Governance, this book will tell a story of a fictional company, Advasco. You will follow key members of the company, including:
Andrea, the CIO of Advasco
Spencer, an Enterprise Architect
Elena, the Chief Architect
Maria, the Service Manager
In each chapter, you will hear a portion of their journey on the path to SOA adoption. Following the narrative of their experiences will be an explanation of the situations that arose for Advasco, along with the role that SOA Governance played in the scenario, either through the lack of it, or through the successful application of people, policies, and process.
Chapter 1 will introduce you to the concept of governance, using the familiar concept of municipal government, introduce its core components of people, policies, and processes, and then illustrate why these are important to the adoption of SOA within an enterprise.
Chapter 2 will introduce you to the beginning of Advasco's SOA journey, and their initial experiences building and consuming services.
In Chapter 3, you will find out what ensues when Advasco tries to expand on its initial successes after some recognition and encouragement from Andrea, the CIO.
Chapter 4 will take you through the experiences of Advasco when one of their production services needs to be upgraded to a new version and support the needs of a new consumer.
Chapter 5 brings Advasco to the inevitable let down after its initial success and addresses the steps that the company takes to keep the SOA effort progressing forward.
Chapter 6 explores the world of run-time SOA governance by discussing the activities of Advasco after a bug in a service is exposed in the production environment.
In Chapter 7, the changes that have occurred in Advasco over the course of their SOA journey are summarized.
Finally, Chapter 8 provides a detailed overview of both the techniques explored in the Advasco story, as well as other options available to you and your organization.
The Appendix shows a list of characters that appear in the Advasco story, their role, and the chapters in which they appear.
