Simplifying Application Development with Kotlin Multiplatform Mobile. Write robust native applications for iOS and Android efficiently

Róbert Nagy

Sharing code between platforms can help developers gain a competitive edge, and Kotlin Multiplatform Mobile (KMM) offers a sensible way to do it. KMM helps mobile teams share code between Android and iOS in a flexible way, leaving room for native development.The book begins by helping you to gain a clear understanding of the Kotlin Multiplatform approach, how it works, and how it is different from cross-platform technologies, such as React Native and Flutter, and code sharing options, such as C++. You'll then see how your team can use this software development kit (SDK) to build native applications more effectively by learning timeless concepts and working through practical examples. As you advance, you'll get to grips with the core concepts, understand why UI sharing fails, and get hands-on with developing a small KMM application. Finally, you'll discover expert tips and best practices, along with production- and adoption-related questions, that will help you take the next step in your project and career.By the end of this Kotlin book, you'll have gained a solid understanding of the capabilities of KMM and be able to share code between Android and iOS flexibly.

High availability is a system design approach and associated service implementation which ensures that a prearranged level of operational performance will be met during a contractual measurement period. High availability is usually a system combined with many different components that achieve different goals. High availability cluster implementations attempt to build redundancy into a cluster to eliminate single points of failure.JBoss EAP6 High Availability is the perfect guide for learning how to apply the newest technologies provided by JBoss to build your high availability system. With a clear explanation of the design of JBoss EAP6 and its clustering components, this book will help you customize each component to fulfill your specific requirements.Throughout the course of this book, you will learn how to build high availability clusters using the projects provided by JBoss. The book begins with an introduction to the design of JBoss EAP6 and its uses. The next step will be to explore the two companion open source projects - mod_jk and mod_cluster. In this section, you will get to grips with the concept of load balancing with mod_jk and mod_cluster. You will also learn how to enable SSL in the clustering environment and how to configure session replication between EAP6 servers.
