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.

Visualizing metrics through Grafana

Let's take a look at some of the open source visualization tools that can be used for distributed tracing, dependency visualization between services, and monitoring dashboards with the data we've collected through Prometheus. First, let's take a look at the Grafana dashboard, which has been built by the Istio community to show monitoring features:

  1. Launch the Grafana dashboard by going to http://grafana.istio.io.
  2. From the left-hand navigation panel, click on the Configuration (gear) and click on Data Sources:

Notice that the backend data source is configured using Prometheus.

  1. Go back to the navigation panel, click on Dashboard, and navigate to Manage.
  2. Next, go to the search bar and type Istio. The search output shows Galley, Mesh, Mixer, Performance, Pilot, Service, and Workload dashboard.
  3. Click on Istio Mesh Dashboard:
