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 rules

A perfect service mesh should establish the ORASTAR rules without having to code anything at the microservice level:

  • Observability: The control plane provides the observability of services running in the data plane.
  • Routing: The routing rules for traffic management can be defined either graphically or through the use of configuration files and then pushed down from the control plane to all the data planes.
  • Automatic scaling: The control plane services automatically scale to handle the increased workload.
  • Separation of duties: The control plane UI allows operations to manage the service mesh independent of the development team.
  • Trust: It pushes down secure communication protocols to the data planes and provides automatic renewal and management of certificates.
  • Automatic service registration and discovery: The control plane integrates with the Kubernetes API...
