Deploying add-on components to provide observability
By now, you know how to deploy Istio and understand some of the most used objects, but you haven’t seen one of the most useful features yet – observability. At the beginning of the chapter, we mentioned that observability is one of our favorite features provided by Istio, and in this chapter, we will explain how to deploy a popular Istio add-on called Kiali.
