Istio is the implementation of a service mesh that improves application resilience as you connect, manage, and secure microservices. In the course of reading this second edition, you will focus on several key microservices capabilities that Istio provides on Kubernetes and OpenShift.
This book explains how to:
* Build more dependable software and deliver it faster than before.
* Create powerful and resilient cloud native applications.
* Improve traffic control, service resiliency, testing, observability, and the security of microservices.
