Solve difficult service-to-service communication challenges around security, observability, routing, and resilience with an Istio-based service mesh. Istio allows you to define these traffic policies as configuration and enforce them consistently without needing any service-code changes.

In Istio in Action you will learn:

• Why and when to use a service mesh
• Envoy’s role in Istio’s service mesh
• Allowing “North-South” traffic into a mesh
• Fine-grained traffic routing
• Make your services robust to network failures
• Gain observability over your system with telemetry “golden signals”
• How Istio makes your services secure by default
• Integrate cloud-native applications with legacy workloads such as in VMs

Reduce the operational complexity of your microservices with an Istio-powered service mesh! Istio in Action shows you how to implement this powerful new architecture and move your application-networking concerns to a dedicated infrastructure layer. Non-functional concerns stay separate from your application, so your code is easier to understand, maintain, and adapt regardless of programming language. In this practical guide, you’ll go hands-on with the full-featured Istio service mesh to manage microservices communication. Helpful diagrams, example configuration, and examples make it easy to understand how to control routing, secure container applications, and monitor network traffic.
