Preface

Much has been written about legacy modernization in the past few years. Most of the books, analyst reports and white papers focus on why you should modernize and theorize at a high level regarding the different approaches and possible outcomes. This book intends to get to the heart of the matter very quickly and into the details of two very well known modernization approaches — SOA Integration and Re-architecturing.

The book is agnostic in terms of hardware and operating systems as most of these have proven to be able to handle the reliability, scalability, and performance of a mainframe system.
