A Cost Group is a logical grouping of resources, usage and costs that can span multiple Subscriptions, Resource Groups and Resources.
In reality, a cloud application is never just a single Subscription or Resource Group. For example, there’s usually multiple environments; DEV, TEST and PROD, not to mention different standards from Group IT for how you manage your Non-Prod resources in Resource Groups.
CloudMonitor allows you to create Cost Groups that map to Business Units, Applications and Cost Centres as opposed to cloud technical structures, which means your Business Unit Owners can now get more accurate cost reports!
