Opis

Much has been written about legacy modernization in the past few years. Most of the books, analysts' 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 provides a detailed guide to how to implement two well known mainframe modernization approaches SOA Enablement and Re-architecture. SOA Integration is a non-invasive approach and allows legacy components to be used as part of an SOA infrastructure quickly and without risk and is often the first step in the larger modernization process. Re-architecture focuses on reverse engineering legacy applications to preserve business knowledge then forward them to modern architectures that take advantage of open and extensible standards. In this book you will learn how to quickly and easily expose a mainframe VSAM data store in an Oracle-based Java EE application. You will also learn how to leverage your mainframe application code to create a new Oracle/Java EE SOA-based application. The book is agnostic in terms of hardware and operating system as most of these have proven to be able to handle the reliability, scalability, and performance of a mainframe system. After reading this book, you will feel much more comfortable that mainframe modernization is possible and can made less risky by following the recommendations and approaches used in the book.
