In this chapter, you have learned how to install Istio using different methods. We discussed the different profiles that are available to install an environment that is suited to a need, such as either a production or a test environment. Installation from the GitHub repository provides options to use a particular version and customized installations. We saw that using the Helm installation is another simple choice that involves using a simple helm install command and override configuration parameters using --set variables. The third method is to do a Helm installation through a cloud provider's catalog. You can request Istio to come pre-configured with a Kubernetes cluster. 

Now that we have successfully installed Istio, we will explore the various features it offers in the upcoming chapters, beginning with traffic management.
