Box 1: copyIndex -
Notice that the name of each resource includes the copyIndex() function, which returns the current iteration in the loop. copyIndex() is zero-based.
Box 2: copy -
By adding the copy element to the resources section of your template, you can dynamically set the number of resources to deploy.
Box 3: dependsOn -
Example:
"type": "Microsoft.Compute/virtualMachineScaleSets",

"name": "[variables('namingInfix')]",
"location": "[parameters('location')]",
