A CostHub allows you to create and maintain an Azure resource bucket that consists of subscriptions and resource groups. This will allow you to compare costs by month and understand your Azure resource bill.
When you create a new CostHub, you will be able to see a month by month comparison of your cost actuals over the last year.
If you set a monthly budget and alert, you can easily ensure that your spending stays on track.
You can click in the top right corner of the screen to export your data to a .csv file.
Edit your CostHub at any time by clicking the menu button.
