Google Cloud Self-Paced Labs



With Istio, you can manage service discovery, traffic routing, and load balancing for your service mesh without having to update your services. Istio simplifies configuration of service-level properties like timeouts and retries, and makes it straightforward to set up tasks like staged rollouts with percentage-based traffic splits.

Istio’s traffic management model relies on the following two components:

  • Pilot , the core traffic management component.
  • Envoy proxies, which enforce configurations and policies set through Pilot.

Pilot architecture

These components enable Istio traffic management features including:

  • Service discovery
  • Load balancing
  • Traffic routing and control


In this lab, you will learn how to perform the following tasks:

  • Review Traffic Management use cases.
  • Understand ingress configuration using an Istio Gateway.
  • Generate traffic, and use Kiali to view routing to multiple versions.
  • Download open source Istio with sample configs, and istioctl.
  • Apply default destination rules, for all available versions.
  • Apply virtual services to route by default to only one version.
  • Route to a specific version of a service based on user identity.
  • Shift traffic gradually from one version of a microservice to another.
