A CostHub is a view type that allows you to create and maintain an Azure resource bucket that consists of subscriptions and resource groups. This will allow you to compare costs, create a budget, and understand your Azure resource bill for a specific project or team in your organization.
If you set a budget, you can easily ensure that your spending stays on track.
Once you create a new CostHub, you can select it with the Change View button in the top ribbon.
You can edit your CostHub at any time by clicking the menu button.
