Introducing Istio Service Mesh for Microservices

Are you in a relentless pursuit to better serve your customers and users? Need to build and deploy cloud-native applications based on the microservices architecture? In your microservices applications are you struggling with reliability and complexity? Istio is the implementation of a service mesh that creates resilience in your applications as you connect, manage, and secure microservices. Red Hatter’s Christian Posta and Burr Sutter introduce you to several key microservices capabilities that Istio provides on Kubernetes and Red Hat OpenShift. In this O'Reilly book learn how: The Istio service mesh enables developers to build better and more dependable software and deliver it faster than before. DevOps teams can use the Istio service mesh to create powerful and resilient cloud-native applications. Istio improves traffic control, service resiliency, testing, observability, and security of your microservices. Cover Red Hat Developer Program Copyright Table of Contents Chapter 1.

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 Kubernetes/OpenShift. Throughout this book, we will use the terms Kubernetes and OpenShift interchangeably. (Open‐ Shift is Red Hat’s supported distribution of Kubernetes.)
