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.

Service mesh architecture

As we discussed in the previous section, we can enforce ORASTAR rules through a control and data plane. Let's go over these concepts in a bit more detail:

  • Control plane: You can use this to push down configurations, policies, and management services to a data plane for controlling routing, traffic, monitoring, discovery, and registration of services. The control plane is responsible for establishing communication between microservices through authentication, authorization, and securing network traffic.
  • Data plane: All of the sidecars of the microservices form the data plane. The control and data plane, when used together, form the service mesh:

In the preceding diagram, the control plane interacts with the data plane to manage the service mesh's outcome. Its core responsibility is to translate, enforce, and forward service traffic from every...
