The emergence of cloud computing within the last two decades has brought ground-breaking innovations and related transformations to the information technology industry. It has revolutionized the way organizations develop, deliver, and operate software applications, as well as brought profound changes to supporting infrastructure, security, and enterprise services.

Well-implemented cloud computing strategy could be a competitive advantage and has already become a differentiating factor in the marketplace for many companies. Amazon, Microsoft, and Google are prime examples of such success. Conversely, cloud computing has also introduced numerous challenges that could lead to higher costs, increased complexity, and missed market opportunities. Hence, it is vital to understand what cloud computing is, what opportunities and challenges it presents, and how to ride the cloud computing wave to benefit your organization without drowning in it.

Thats where this book comes in. Its objective is to serve as a comprehensive, coherent, and systematic cloud migration guide. Experiences shared in this book are drawn from real-life migration projects and contain practical advice, as well as step-by-step architecture, design, and technical implementation instructions using sample application code from GitHub. Following this book will provide much needed support to your teams, and help you successfully complete the application cloud migration journey.

This text is primarily designed with software developers, team leads, technical development managers, DevSecOps engineers, production support technicians, and software architects in mind. Their day-to-day activities include architecting, designing, developing, delivering, and operating software in the cloud environment. In addition, this book will benefit infrastructure, network, security, and operations engineers, who in turn, can provide better support for the software development product teams.

The book provides structured and deep insights into cloud-related characteristics, paradigm shifts, cloud-native tools, methodologies, and technologies, plus sound engineering and cost-efficient design techniques. You will find valuable insights that will help you identify cloud-related training requirements and help you develop the skillset to successfully migrate. These newly acquired skills will future-proof your technology career for years to come.

At the end of the day, this book aims to be your table-top reference guide. It provides straight migration advice and guides you to a solution as well as points you to carefully selected supplementary materials for additional research.

Application Cloud Migration Structure

Part I: Introduction to Cloud Computing

This part starts with an introduction to cloud computing and establishes a basic understanding of the different types of cloud computing characteristics. It lists business and technical motivational factors and benefits and explains cloud-native technologies and core paradigm changes within the application, infrastructure, delivery, operations, and security technology and service areas. In addition, it establishes and elaborates on major migration areas: software development (application code, data, infrastructure, security and configuration), software delivery (pipeline and automation), and software operations (observability, cost, and platform management). It concludes with an introduction to a high-level migration process, including major steps to be applied to each migration area. This blueprint becomes our roadmap for the rest of the book, and could be adapted by the reader for a specific migration project.
