Information Systems Transformation - Architecture Driven Modernization Case Studies (Electronic book text)

Every enterprise has large investments in mainframe systems - giant infrastructures that manage business operations around the globe, and are the lifeblood of the corporation. Despite the vast changes in information technology in recent years, most of the mainframe systems in use were designed and implemented some time ago, at the enterprise's birth, and are therefore hard to maintain. Integration with newer systems is difficult if not impossible because new corporate software use completely different and incompatible technologies. This necessitates frequent and costly modifications to the existing system, which impedes optimum operational efficiency. Therefore, IT management teams are now placing modernization efforts at the core of their current objectives. Architecture-Driven Modernization (ADM) restores the value of entrenched systems by capturing and retooling various aspects of existing application environments, allowing old infrastructures to deliver new solutions and communicate with modern technology.
This book provides a practical guide to organizations seeking ways to understand and more effectively leverage existing systems as part of their information management strategies. It includes an introduction to ADM disciplines and standards as well as a series of scenarios outlining how ADM is applied to various initiatives. Drawing upon lessons learned from real modernization projects, it distills the theory and delineates principles, processes, and best practices for every industry, ensuring the book's leading position as a reference text for all of those organizations relying on instilled systems to maintain their viability.
