Infrastructure cost fell by up to 62%.
Problem

Infrastructure cost was high relative to game revenue, which hurt profitability.

Approach

Revenue metrics and infrastructure cost were monitored together. Python found unused resources across every cloud automatically each day.

Result

Infrastructure cost fell by up to 62%.

What I learned

I learned that cost is easier to judge against revenue than as an amount on its own. Putting infrastructure cost next to revenue metrics made it clear which resources affect profitability and what to cut first. Cost leaks also do not end after one cleanup, so detecting unused resources every day in Python, instead of someone looking now and then, was what kept the savings in place. Detection alone saves nothing until resources are actually removed, which showed me that the next step in cost management is a flow that takes each finding quickly to cleanup approval and action.
