• Resource groups are simply groupings of resources.
• When you create a resource, you’re required to place it into a resource group.
• There aren’t hard rules about how you use resource groups, so consider how to set up your resource groups to maximize their usefulness for you

• Billing boundary: This subscription type determines how an Azure account is billed for using Azure. You can create multiple subscriptions for different types of billing requirements. Azure generates separate billing reports and invoices for each subscription so that you can organize and manage costs.
• Access control boundary: Azure applies access-management policies at the subscription level, and you can create separate subscriptions to reflect different organizational structures. An example is that within a business, you have different departments to which you apply distinct Azure subscription policies. This billing model allows you to manage and control access to the resources that users provision with specific subscriptions.

• You organize subscriptions into containers called management groups and apply governance conditions to the management groups.
• All subscriptions within a management group automatically inherit the conditions applied to the management group,
  • the same way that resource groups inherit settings from subscriptions and
  • resources inherit from resource groups.

• E.g. You could limit VM locations to the US West Region in a group called Production.
