Istio is an open platform to connect, secure, control and observe microservices, also known as a service mesh, on cloud platforms such as Kubernetes in IBM Cloud Kubernetes Service and VMs. With Istio, you can manage network traffic, load balance across microservices, enforce access policies, verify service identity, secure service communication, and observe exactly what is going on with your services.

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.


After you complete this course, you'll be able to:

  • Download and install Istio in your cluster

  • Deploy the Guestbook sample app

  • Use metrics, logging, and tracing to observe services

  • Set up the Istio Ingress Gateway

  • Perform simple traffic management, such as A/B tests and canary deployments

  • Secure your service mesh

  • Enforce policies for your microservices


You will perform the following exercises in the lab.
