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.

  1. The control and data plane can be in a single namespace if so desired.

  1. You can add a debug sidecar to a microservice without having to restart the pod.

A) True
B) False

  1. The retry budget helps us avoid a retry storm, and we don't need to do any configuration in Linkerd to achieve this.

A) True
B) False

  1. For automatic sidecar injection, Istio needs a labeled namespace with istio-injection=enabled, while Linkerd needs a namespace annotated with linkerd.io/inject...
