How to use a existing Microsoft.Web/serverfarms in a Azure Resource Manager Template?
<p>I want to deploy a website (Microsoft.Web/sites) resource to a existing hosting plan (Microsoft.Web/serverfarms) without having to define the sku, workersize, etc. in the ARM template. It should just use the hosting plan as-is without changing it. But the sku seems to be required for the hosting plan definition and the hosting plan definition seems to be required for the website definition.</p>

<p>At the moment we read the sku of the hosting plan and set it as a parameter in the ARM template, but sometimes it still triggers a scaling operation in azure and restarts all websites on the hosting plan.</p>
