Using service discovery in a cloud provider

While the Kubernetes service discovery we’ve looked at so far is great and all, you more than likely have some regular old servers that need to be monitored too! How can we discover those? If you’re one of the thousands of people running virtualized infrastructure in the cloud, you may be entitled to dynamic service discovery.
