If you are looking for an introduction into the world of Istio, the service mesh platform, with detailed examples, this is the book for you. This book is for the hands-on application architect and development team lead focused on cloud- native applications based on the microservices architectural style. This book assumes that you have had hands-on experience with Docker, and while Istio will be available on multiple Linux container orchestration solutions, the focus of this book is specifically targeted at Istio on KubernetesOpenShift. Throughout this book, we will use the terms Kubernetes and OpenShift interchangeably. (Open? Shift is Red Hat’s supported distribution of Kubernetes.)
