PARAMETERS: Values that are provided when deployment is executed to customize resource deployment.

VARIABLES: Values that are used as JSON fragments in the template to simplify template language expressions.

Could you explain your query bit more to understand better? Is there any template or script which you are referring to?

It's a generic question. In any VM deployment template there are Parameters and Variables. So when is it the one or the other? And how can it be that as in my example NetworkSecurityGroupName is a variable while VirtualVnetName is a parameter.

I'm following a MOC training and the templates comes from GitHub.

Any entry like that can be either, you could have a template with no parameters and all variable or the reverse.

It all depends on level of interaction required at deployment phase.

Okay. A good begin. I'll add:

Value is free to insert. Think about Password.

Variable is something you must choose. Think about a region. You can choose "West Europe". "South Europe" is not an option.
