You may add any number of public cloud providers (using API keys or tokens) to your Nova organization. This allows Nova to deploy into your cloud, as well as read information about backends (your virtual machines).
Nova's Cloud API integrations allow you to configure your Nova ADCs to automatically send traffic to matching tags, or AMI IDs on the cloud when creating backends.
Additionally, you can deploy Nodes to a cloud with the click of a button, and primarily this allows cloud autoscaling.
IP Access Requirements
To install Nova to a freshly launched cloud instance you need to ensure that we will be able to connect on port 22. We handle this for the given cloud instance, but you may have global rules that prevent it.
The IP addresses Nova uses for provisioning new cloud servers are:
220.127.116.11 18.104.22.168 22.214.171.124
Cloud Autoscalers are dynamic services which scale up and down the compute requirements based on your load.
