Understanding AWS Config Cost Differences Between Regions
Asked by

Hey there! I'm trying to get a grip on the high costs we're seeing with AWS Config. We have servers in two regions (East and West), each with about four EC2 instances. After cleaning up some security issues, I've noticed a massive price difference; we're looking at around $1 in one region versus $90 in another over a week. When I checked our billing, I found that one region recorded 25 Configuration Items while the other recorded over 30,000! I'm curious to know how I can find out what these items are. I did read a blog about downloading data and using Athena for this, but I'm not familiar with it at all. Is there a way to use the AWS Console or command line to pinpoint these directives? Also, if anyone has ideas on what might have triggered this jump in configuration items during the security cleanup, I'd appreciate it!

I found this blog to be really helpful: [Vantage's AWS Config Pricing](https://www.vantage.sh/blog/aws-config-pricing). Just a heads up, the example queries might need some tweaking, but they’re pretty intuitive once you dive in.

Check if you have any custom config rules scheduled to monitor all objects like snapshots or volumes. This can really drive up your costs. You might want to adjust the rules to only check resources when they change. That could really help cut down on your bill!

CuriousCoder42: That sounds like a possibility! I'm not sure what settings were enabled during the security checks.
