The definitive guide for designing and delivering reliable and high-performing persistence layers using Java in the cloud-native agePurchase of the print or Kindle book includes a free PDF eBookKey Features:Uncover database patterns for designing readable and maintainable architectures and Java applicationsMaster various techniques to overcome application and architecture persistence challengesDiscover painless application modernization with change-data-capture powered by cloud-native technologiesBook Description:Having a solid software architecture breathes life into tech solutions. In the early stages of an application's development, critical decisions need to be made, such as whether to go for microservices, a monolithic architecture, the event-driven approach, or containerization. In Java contexts, frameworks and runtimes also need to be defi ned. But one aspect is often overlooked - the persistence layer - which plays a vital role similar to that of data stores in modern cloud-native solutions. To optimize applications and data stores, a holistic understanding of best practices, technologies, and existing approaches is crucial.This book presents well-established patterns and standards that can be used in Java solutions, with valuable insights into the pros and cons of trending technologies and frameworks used in cloud-native microservices, alongside good Java coding practices. As you progress, you'll confront the challenges of cloud adoption head-on, particularly those tied to the growing need for cost reduction through stack modernization. Within these pages, you'll discover application modernization strategies and learn how enterprise data integration patterns and event-driven architectures enable smooth modernization processes with low-to-zero impact on the existing legacy stack.What You Will Learn:Gain insights into data integration in Java services and the inner workings of frameworksApply data design patterns to create a more readable and maintainable design systemUnderstand the impact of design patterns on program performanceExplore the role of cloud-native technologies in modern application persistenceOptimize database schema designs and leverage indexing strategies for improved performanceImplement proven strategies to handle data storage, retrieval, and management efficientlyWho this book is for:If you're a developer, engineer, or software architect working in the field of software development, particularly with a focus on Java solutions, this book is for you.
