With Nova you describe a service, not a server. Once you are ready to deploy that service to one or more servers you are "Deploying" in Nova terminology. This attaches that ADC configuration to Nodes.
Primer: ADCs are Templates
With Nova, an ADC is really an intent or configuration template. It describes the way a Node or set of Nodes should behave, what traffic they accept, what rules are applied to it, and where that traffic goes.
Once it is attached to one or more Nodes it becomes a deployed ADC - ready to accept traffic. Any changes to the ADC are automatically synchronized to all Nodes within seconds.
Deploying an ADC
Once you have created an ADC you can deploy it. Alternatively, you can add or modify the attached Nodes to an ADC by selecting Attachments in the ADC header menu.
This will link the ADC configuration to one or more Nodes, ensuring they are always running your ADC template, and all the requirements of it (WAF, Geofencing, Logging, etc).
To attach an ADC you must have at least one online Node that is ready to receive the configuration. This Node will then function as the ADC, and you can send traffic directly to the Node (not via Nova).
Deploys are Instant
Regardless of the number of Nodes you have, an ADC deploy will sync to your Nodes in around 2 seconds. Remember when making changes they will apply right away!
Single ADC Deployment
When deploying an ADC you will see the status of your latest deploy inside the ADC view.
Multiple ADCs per Node
You can attach multiple ADCs to a single Node if you wish, however, you must ensure there is no IP:port clash between them. For example, you cannot deploy two ADCs that both listen on 0.0.0.0:80 as they will clash.
Should you want to have multiple websites for example, deploy one ADC with multiple Backends enabled instead.
ADC Deployment History
You may also see the deployment history under the Deployments menu item at any time, for all ADCs.
