Implement Configuration Management Databases that Deliver Rapid ROI and Sustained Business Value

Implementing an enterprise-wide Configuration Management Database (CMDB) is one of the most influential actions an IT organization can take to improve service delivery and bridge the gap between technology and the business. With a well-designed CMDB in place, companies are better positioned to manage and optimize IT infrastructure, applications, and services; automate more IT management tasks; and restrain burgeoning costs. Now, there’s an objective, vendor-independent guide to making a CMDB work in your organization. The CMDB Imperative presents a start-to-finish implementation methodology that works and describes how the CMDB is shifting to the superior Configuration Management System (CMS).

Expert CMDB industry analyst Glenn O’Donnell and leading-edge architect and practitioner Carlos Casanova first review the drivers behind a CMDB and the technical, economic, cultural, and political obstacles to success. Drawing on the experiences of hundreds of organizations, they present indispensable guidance on architecting and customizing CMDB solutions to your specific environment. They’ll guide you through planning, implementation, transitioning into production, day-to-day operation and maintenance, and much more. Coverage includes

  • Defining the tasks and activities associated with configuration management

  • Understanding the CMDB’s role in ITIL and the relationship between CMDBs and ITIL v3’s CMS

  • Building software models that accurately represent each entity in your IT environment

  • Ensuring information accuracy via change management and automated discovery

  • Understanding the state of the CMDB market and selling the CMDB within your organization

  • Creating federated CMDB architectures that successfully balance autonomy with centralized control

  • Planning a deployment strategy that sets appropriate priorities and reflects a realistic view of your organization’s maturity

  • Integrating systems and leveraging established and emerging standards

  • Previewing the future of the CMDB/CMS and how it will be impacted by key trends such as virtualization, SOA, mobility, convergence, and “flexi-sourcing”

Prologue Prologue

This discussion comes from many years of experience in this field, watching companies start and stop their initiatives for a variety of reasons, most of which had some merit but almost all of which were simply postponing the inevitable. Some have survived punitive outsourcing by fighting against the tide of adoption. How much longer they can prevail depends upon their continued vigilance. We hope this book helps all companies succeed by giving them a guide to this vigilance.

As authors of this book, we began to form our vision together, discussing the concepts of federation, leveraging of the DMTF CIM models and usage patterns in 2003 and 2004. We won’t reveal who first suggested it, but one day during one of our usual exchanges, we decided to write this book. We both heard the same questions and concerns about the CMDB and always found ourselves giving the same responses. It was clear that a comprehensive and authoritative guide was needed and that no books existed to offer the pragmatic view. The timing of ITIL v3 and the CMDB Federation Working Group appearing on the scene told us this was the right time to do it. In hindsight, we now think we were right even more than we did then. We hope you agree.

We are excited that aspects of our vision are starting to become a reality but are also very disappointed that more companies didn’t move faster to address systemic foundational problems within their organizations. We have seen, and in some cases been directly impacted by, the failure of companies to address some of these systemic issues. Our mission is to help prevent such nightmares. The CMDB (more accurately, the CMS) holds great promise as one of the greatest forces toward the dream of disciplined IT service management. We trust The CMDB Imperative will help you to realize this dream and avoid the nightmares.
