Istio is an open platform to connect, secure, and manage a network of microservices, also known as a service mesh, on cloud platforms such as Kubernetes in the IBM Cloud Kubernetes Service. With Istio, You can manage network traffic, load balance across microservices, enforce access policies, verify service identity on the service mesh, and more.In this course, you learn how to install Istio alongside microservices for a simple mock application called Guestbook. When you deploy Guestbook's microservices into an IBM Cloud Kubernetes Service cluster where Istio is installed, you inject the Istio Envoy sidecar proxies in the pods of each microservice. Important: Some configurations and features of the Istio platform are still under development and are subject to change based on user feedback. Allow a few months for stabilization before you use Istio in production.
