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 understood the overall architecture of BookInfo and how to install the application through a simple deployment of its YAML file on Kubernetes. We also learned how to check BookInfo's availability for pods, services, and deployments and validated its service-based IP address for all six services. Now that we have installed the demo application, we will be able to understand Istio's different service mesh capabilities.

In the next chapter, we will jump straight into the installation of Istio's service mesh and share best practices around how each install process works. Thereafter, we will use the BookInfo application we have just installed to explain Istio's service mesh capabilities, such as traffic management, security, telemetry, and overall observability.
