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.

Tracing with Jaeger

Jaeger is an open source tool (https://jaegertracing.io) that recently graduated from the CNCF project. It provides distributed transaction monitoring, service dependency information, and span tracing using an open standard specification (https://github.com/opentracing/specification). Let's take a look at how to perform tracing with Jaeger:

  1. Open http://jaeger.istio.io and use admin/admin as the user ID and password.

If the curl command for driving traffic has stopped in the command-line window, start it again in order to send traffic to the productpage.

  1. Select the productpage.istio-lab service from the drop-down and click Find Traces:
The graph shows the duration, while the bottom section shows the data that has been collected from productpage tracings
  1. Click on the productpage.istio-lab.svc.cluster.local service and visualize the distributed...
