Preface
Modernization requires a multi-dimensional approach. There is a lot to understand when you embark on a digital transformation journey and modernize your platforms, which includes building new applications and retiring legacy solutions. As your journey to the cloud matures, you will want to accelerate your modernization and maximize its value. This book is designed to help you develop appropriate knowledge on the various aspects of modernization using Amazon Web Services (AWS). You will gain insights that will enable you to make decisions and reach new levels of operational efficiency, increased scalability, and improved performance and resiliency on the cloud.
As per the Gartner research as of 2022, 70% of workloads will be on the cloud by 2024, and organizations need a cloud strategy to leverage the advantages of cloud computing. A cloud strategy is a living document that guides teams to leverage the advantages of cloud computing within their organization. Many organizations have no cloud strategy or only think they have one.
A cloud strategy is not an executive mandate or the same as an implementation/adoption/migration plan. Cloud-first is a common principle specified in cloud strategies. By itself, it is not a strategy. Devising a broad strategy requires the alignment of multiple stakeholders and accommodating scenarios, cloud services, vendors, and non-cloud environments.
This book covers a phased approach when it comes to relevant topics on modernization, not just for applications but also for databases, storage, networks, and security. By referencing the best practices and adoption patterns, this book provides a comprehensive view of the knowledge required to consume new technology and to deliver portfolio, application, and infrastructure value faster. This book will also guide you through strategies to simplify your business operations, architecture, and overall engineering practices.
We begin with introducing cloud migration for your existing workloads, evaluating modernization readiness for your workloads, prescriptive guidance for cloud migration, and choosing a cloud vendor. This is then followed by a modernization roadmap for your workloads with AWS services for technology categories such as Compute, Storage, Databases, Security, Networking, and Cloud Operations. Each chapter includes use cases for using the AWS services and case studies on how companies of various industries can take advantage of modernization.
