# Helloworld service

This sample includes two versions of a simple helloworld service that returns its version
and instance (hostname) when called.
It can be used as a test service when experimenting with version routing.

This service is also used to demonstrate canary deployments working in conjunction with autoscaling.
See [Canary deployments using Istio](https://istio.io/blog/2017/0.1-canary).
