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.

Exploring the Reliability Features of Linkerd

In this chapter, we will go through Linkerd's reliability features, such as automatic load balancing through dynamic requests routing, service profiles, retries, timeouts, and proactive error code hunting.

This chapter will explain the traffic management capabilities of a service mesh. Understanding this framework is necessary if you want to use networking resources that coordinate, restrict, and scale traffic throughout microservices.

We will be covering the following topics in this chapter:

  • Load balancing traffic between services in the booksapp application
  • Understanding and creating service profiles
  • Routing traffic between the booksapp application for a newly created service profile
  • Deploying service profiles for the booksapp application using Swagger specs
  • Understanding aggregated routing for the booksapp application
  • Enabling...
