By: Anand Rai

Overview of this book

Istio is a game-changer in managing connectivity and operational efficiency of microservices, but implementing and using it in applications can be challenging. This book will help you overcome these challenges and gain insights into Istio's features and functionality layer by layer with the help of easy-to-follow examples. It will let you focus on implementing and deploying Istio on the cloud and in production environments instead of dealing with the complexity of demo apps.  You'll learn the installation, architecture, and components of Istio Service Mesh, perform multi-cluster installation, and integrate legacy workloads deployed on virtual machines. As you advance, you'll understand how to secure microservices from threats, perform multi-cluster deployments on Kubernetes, use load balancing, monitor application traffic, implement service discovery and management, and much more. You’ll also explore other Service Mesh technologies such as Linkerd, Consul, Kuma, and Gloo Mesh. In addition to observing and operating Istio using Kiali, Prometheus, Grafana and Jaeger, you'll perform zero-trust security and reliable communication between distributed applications. After reading this book, you'll be equipped with the practical knowledge and skills needed to use and operate Istio effectively.

In this chapter, we read about various troubleshooting techniques as well as best practices for configuring and operating istio. By now, you should have a good understanding of various ports exposed by istio and how they can help diagnose any errors in the mesh. You also read about debugs and access logs produced by Envoy and istiod and how they can help you pinpoint the root cause of errors. istio provides various tools in its diagnostic toolkit that are very helpful for troubleshooting and analyzing issues and errors in the Service Mesh.

Security is of utmost importance when running the Service Mesh, which is why we discussed various attack vectors for the control and data planes. You should now have a good understanding of the list of controls you can put in place to secure the Service Mesh. Finally, we read about how to automate best practices using OPA Gatekeeper to catch most, if not all, non-compliant configurations. You learned how to set up OPA Gatekeeper, how to...
