The goal of this experiment is to measure the amount of latency that is added to a simple service by the addition of various Istio Components. To isolate the contribution of each component, many combinations of avialable components were tested and recorded.

These files will help you follow along with our Learn Kubernetes with Google series (TODO link to YouTube). In them, you take the role of a service operator who's kubernetes application is misbehaving, and we will use Istio to help identify, mitigate, and resolve the misbehavior. Each step corresponds to one five minute episode, and teaches a core concept of Istio.
Run the following command before starting the series to install a slightly broken version of our bookinfo service into your kubernetes cluster.
curl https://gist.githubusercontent.com/therealmitchconnors/b88965a820768e76e02b1b8e4546b64c/raw/install.sh | bash
NOTE: for platforms other than GKE, you may need to modify the gatewayClassName parameter to fit your cloud provider of choice.
