How to tell which AWS services you’re using

Amazon Web Services is a behemoth. When you’re using it – whether you’ve completely set up your account from scratch yourself; have inherited it from someone else; or are using it within a team of people – from time-to-time it becomes necessary to figure out just which AWS services you’ve set up.

As far as I can tell there’s no unified list of what you’ve created, and of course it’s exacerbated by the sheer number of AWS services and regions.

So to help me out when I need to do this again next time – and to help you out if you’ve stumbled across this post – here’s some quick ways to determine which services your AWS account is using:

• Visit Billing (which does not care what region you’re in) and check the dashboard’s Month-to-Date Spend by Service, or browse through the detailed bills.
• Visit CloudWatch’s metrics to see which metric categories and individual metrics are available (region specific, and it won’t cover everything, but it can be helpful).
• If you’ve turned on billing alerts in your Billing Preferences, visit CloudWatch’s metrics in us-east-1 (the default region) and browse the metrics in the Billing category.
• Visit the Tag Editor, select all the regions, and search for All resource types (note that only some resource types are supported by the tag editor).
