The company's AWS runs a lot of different services, EC2,S3,VPC and so on, and they belong to more than 20 different clinics. The previous administrator did not do a very good Tag, so the bill at the end of each month can only see a large amount of total expenditure. For each service, it is difficult for each clinic to determine the specific expenditure. As a result, all the expenses come from the budget of the IT department, rather than apportioned to the actual clinics.

To solve this problem, you can customize the Tag tag for each service, then activate the custom tag in the Cost Allocation Tag console, and after a day, you can filter the query based on the self-defined tag in the billing bill.

For example, in order to distinguish between clinics, I defined a Tag,key that is Clinic,value, which is the name of each clinic.

Because I have hundreds of volume and thousands of Snapshot, Douzi wrote a simple PowerShell script to add tags. Manually add the corresponding tag on the EC2 instance, then add Tag according to the volume associated with EC2, and then associate snapshot with volume to add Tag

After the execution, it is about like this. After confirming the work, just put him in the task plan and run automatically.

Then, 24 hours later, log in to the console of billing, categorize according to Tag, and you can see the expenditure records of each clinic.
