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 covered Consul in a Kubernetes environment. We covered service discovery, intentions, mTLS, key-value stores, and external services registration. It is important to note that Consul works in heterogeneous environments spanning multiple data centers. This makes it a very good candidate for service discovery and for providing mTLS out of the box while covering both Kubernetes as well as non-Kubernetes environments.

You can use this service discovery knowledge process to build a catalog of enterprise services so that your cloud-native applications can discover and use them.

In the next chapter, we will go through the traffic management capabilities of Consul Connect in the Kubernetes environment. You will learn how easy it is to shift and route traffic between different versions of the same service.
