Most organizations rely on complex enterprise information systems (EISs) to codify their business practices and collect, process, and analyze business data. These EISs are large, heterogeneous, distributed, constantly evolving, dynamic, long-lived, and mission critical. In other words, they are a complicated system of systems. As features are added to an EIS, new technologies and components are selected and integrated. In many ways, these information systems are to an enterprise what a brain is to the higher species--a complex, poorly understood mass upon which the organism relies for its very existence. To optimize business value, these large, complex systems must be modernized--but where does one begin? This book uses an extensive real-world case study (based on the modernization of a thirty year old retail system) to show how modernizing legacy systems can deliver significant business value to any organization.

PREFACE The financial services industry is at the precipice of a profound transformation. As technology continues to evolve, so too does the need for banks and financial institutions to modernize their core systems, many of which are deeply entrenched in legacy infrastructure. These outdated systems, while functional, are increasingly becoming impediments to growth, innovation, and customer satisfaction. To remain competitive and relevant in the modern world, banks must embrace digital transformation, adopt new technologies, architectures, and processes that enable them to meet the expectations of today’s digital-first customers. “Modernizing Legacy Banking Systems: A Practical Guide to Digital Transformation” is written for banking executives, IT leaders, and financial technology professionals seeking to navigate the complex journey of modernizing their legacy systems. In this book, we delve into the strategic, technical, and operational considerations of digital transformation in the banking sector. We examine the key challenges faced by institutions operating with legacy systems and provide practical guidance on how to evolve these systems to harness the full potential of modern technologies like cloud computing, data analytics, artificial intelligence (AI), and open APIs. This guide aims to provide a comprehensive, step-by-step approach to the modernization process, exploring everything from understanding the fundamentals of legacy banking systems to leveraging new technologies for improved operational efficiency, customer experience, and regulatory compliance. With case studies, industry best practices, and expert insights, we outline how banks can transform their IT infrastructure while minimizing risk and ensuring that customer needs remain at the heart of the process. The traditional model of banking—characterized by rigid, monolithic, and often siloed systems—is no longer suitable in an era where customers expect seamless, personalized, and always-on services. Modern banks are increasingly turning to cloud computing, data analytics, artificial intelligence, and API-driven architectures to provide more agile, scalable, and cost-effective solutions. Yet, the journey to digital transformation is complex. The scale of change required is vast, and each institution’s path will be unique, depending on its existing technology landscape, organizational culture, and strategic goals. We also explore the critical importance of data management, cybersecurity, and compliance in this transformation. As banks modernize their systems, they must ensure that security and privacy remain top priorities. Ensuring compliance with financial regulations, including GDPR, CCPA, and Basel III, is essential for both mitigating risk and maintaining customer trust in an increasingly interconnected digital world. The challenges of modernizing legacy banking systems are significant, but the opportunities are equally vast. With the right tools and strategies in place, banks can not only improve their internal operations but also enhance customer satisfaction, drive innovation, and create new avenues for growth. From improving operational efficiency to offering new services, the benefits of a well-executed digital transformation are clear. This book aims to serve as both a roadmap and a reference for financial institutions at any stage of their modernization journey. Whether you’re just beginning to explore the potential of digital transformation or are during overhauling your systems, this guide provides valuable insights and actionable strategies that can help ensure success. In the chapters that follow, we will walk you through the essential components of modernizing legacy banking systems, covering topics ranging from the technical architecture of cloud-based core banking platforms to the role of artificial intelligence in improving customer service. By the end of this guide, readers will have a clear understanding of how to navigate the complexities of digital transformation and unlock the full potential of modern banking technology. As we move forward into this digital age, one thing is certain: banks must evolve, adapt, and embrace change if they are to thrive. This book will help you take the first steps on that transformative journey. Authors

While containers, microservices, and distributed systems dominate discussions in the tech world, the majority of applications in use today still run monolithic architectures that follow traditional development processes. This practical book helps developers examine long-established Java-based models and demonstrates how to bring these monolithic applications successfully into the future. Relying on their years of experience modernizing applications, authors Markus Eisele and Natale Vinto walk you through the steps necessary to update your organization's Java applications. You'll discover how to dismantle your monolithic application and move to an up-to-date software stack that works across cloud and on-premises installations. Learn cloud native application basics to understand what parts of your organization's Java-based applications and platforms need to migrate and modernize Understand how enterprise Java specifications can help you transition projects and teams Build a cloud native platform that supports effective development without falling into buzzword traps Find a starting point for your migration projects by identifying candidates and staging them through modernization steps Discover how to complement a traditional enterprise Java application with components on top of containers and Kubernetes
