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.

Summary

In this chapter, we demonstrated Istio's traffic management capabilities for traffic shifting, setting request timeouts, controlling Ingress and Egress traffic, circuit breaking to protect services from overload and attacks, and mirroring traffic from one route to another route.

These were the breakthroughs from the earlier concepts of achieving the same results either through coding in the application or by using libraries for every language. The capability to control traffic at the edge of the cluster gives operations staff ease-of-use to manage the application infrastructure dynamically and resiliently without needing intervention from developers. As an example, it is possible to completely block access to any external service from the distributed microservices application except whitelisted service entries.

It is worth noting that all of the features we learned...
