one of the good things about azure cost management is that it gives reports whats costing you all that money ….i still remember 10 years ago , where we had built a CMDB and using that for cost management and it became an expensive task just to get insight on the costs for the on- prem infrastructure ….in Azure it takes a few clicks and you have the cost analysis ready
Here is a report from one of my subscription
i had spent the bulk of money in running an app service which i never really used
this report quickly helped me narrow down what the costs were, where it was running etc .
i quickly deleted the resource and i was good ….
