Just a quick reminder to myself.

In order to set the “always on” property on a Azure Web App when provisioned from an ARM template, the resource should look like this

 {
            "apiVersion": "2015-06-01",
            "name": "[parameters('siteName')]",
            "type": "Microsoft.Web/Sites",
            "location": "[parameters('siteLocation')]",
            "dependsOn": [ "[concat('Microsoft.Web/serverFarms/', parameters('hostingPlanName'))]" ],
            "tags": {
                "[concat('hidden-related:', resourceGroup().id, '/providers/Microsoft.Web/serverfarms/', parameters('hostingPlanName'))]": "empty"
            },
            "properties": {
                "name": "[parameters('siteName')]",
                "serverFarmId": "[parameters('hostingPlanName')]",
                "siteConfig": {
                    "AlwaysOn": true
                }
            },
            "resources": [
                {
                    "apiVersion": "2014-11-01",
                    "type": "config",
                    "name": "connectionstrings",
                    "dependsOn": [ "[concat('Microsoft.Web/Sites/', parameters('siteName'))]" ],
                    "properties": {
                        "MetadataGovernance": {
                            "value": "[concat('Data Source=tcp:', reference(concat('Microsoft.Sql/servers/', parameters('serverName'))).fullyQualifiedDomainName, ',1433;Initial Catalog=', parameters('databaseName'), ';User Id=', parameters('administratorLogin'), '@', parameters('serverName'), ';Password=', parameters('administratorLoginPassword'), ';')]",
                            "type": 2
                        }
                    }
                }
            ]
        }

Note the siteConfig element under the “Microsoft.Web/Sites” resource.

The following is a list of supported site properties (Note, not sure all of them can be set)
