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.

Consul's control and data planes

Consul is easy to understand and use. It is highly available and dynamically distributed. This section will detail how Consul works as a service mesh and its architecture components for the control plane and data plane.

Consul is configured as a control plane that provides four main functionalities: service discovery, secure communication, resource configuration, and network segmentation. These components are managed by a cluster manager (Consul server) to provide a robust service mesh.

Consul provides a data plane through the use of a proxy and native integration model with microservices. It is shipped with the popular sidecar Envoy (built by Lyft) proxy. This can be seen in the following diagram:

The preceding diagram shows the Consul control and data planes. Some primary features of Consul's control plane are as follows:
