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 Istio Traffic Management Capabilities

In this chapter, we will focus on traffic management and how to split and steer network connections between different versions of microservices. We will detail the different ways this can be accomplished, identify challenges, and list the best practices.

By the end of this chapter, you will be able to create and deploy Istio-specific Kubernetes objects such as the gateway, virtual service, and destination rule, which configure incoming and outgoing requests to Istio's demo application. You will also learn how to enable and disable traffic patterns to access Istio's demo application regarding traffic routing, traffic shifting, canary deployments, fault injection, circuit breaker, ingress and egress traffic patterns, and traffic mirroring

In a nutshell, this chapter covers the following topics:
