Mastering Service Mesh

By: Anjali Khatri, Vikram Khatri

Overview of this book

Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment. You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability. By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.

Chapter 13: Exploring Istio Telemetry Features

  1. True A sidecar proxy sends asynchronous telemetry data to backend services.
  2. False Observability and monitoring a system are two different things.
  3. True The recommended web UIs for Istio's monitoring and observability features are Grafana, Prometheus, Kiali, and Jaegar.
  4. False Port forwarding is not the only way to access different web UI components. Ingress rules and node port mechanisms can also be used to access a web UI.
  5. True Istio reports multiple spans within a microservice chain.
  6. True Prometheus is a web UI tool that can visualize collected data or metrics.
  7. True Custom dashboards in Grafana provide details for inbound and outbound workloads.
  8. True All mis-configurations are highlighted in red under the YAML viewer in Kiali.
