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, you learned that Istio is a very feature-rich open source service mesh project that uses adapters to integrate with external telemetry, authentication, authorization systems. As we have seen, the four main categories of Istio are Traffic Management, Security, Policies, and Telemetry, all of which are covered in detail in their own chapters.

Istio's architecture of Pilot, Mixer, Galley, and Citadel forms a control plane, while the proxies attached to the service pods form the data plane, which provides a complete service mesh with a separation between development and operations. The Istio service mesh is a very powerful tool in the hands of the SRE team and is used to control traffic, manage security, implement policies, and observe the service mesh.

Pilot, as its name suggests, is the main navigator for the Envoy engines and steers the application...
