In this course, you can see how to install Istio alongside microservices for a simple mock app called Guestbook. When you deploy Guestbook's microservices into an IBM Cloud Kubernetes Service cluster where Istio is installed, you can choose to inject the Istio Envoy sidecar proxies in the pods of certain microservices.
