Our cloud bill has jumped 40% in three months because different dev teams are spinning up expensive instances. How can we implement a FinOps framework to gain visibility and control?

FinOps is about creating a culture of financial accountability. The first step is "Visibility." You need a strict tagging policy—if a resource isn't tagged with a "Project" and "Owner," it gets deleted automatically. This allows you to show each dev team exactly what they are spending. Next is "Optimization." Encourage teams to use Spot Instances for non-production workloads and Reserved Instances for steady-state apps. By shifting the responsibility of cost from the finance department to the engineers who are actually clicking the buttons, you naturally see a reduction in waste.
Does implementing such strict tagging and automated deletion policies risk slowing down development speed or causing accidental production outages?
We use a tool called CloudHealth. It gives us a great dashboard that breaks down spending by department, which makes those monthly FinOps meetings much more productive.
Tools like CloudHealth or even the native AWS Cost Explorer are essential. You can't manage what you can't measure, and Diana is right that clear dashboards are key.
It’s a balance, Bryan. We don't start with "delete." We start with "notify." We send automated Slack alerts to owners of untagged resources. If they don't fix it in 48 hours, then we stop the instance. This gives them a chance to fix it without breaking anything. It actually speeds things up in the long run because it forces teams to be more organized and thoughtful about the infrastructure they deploy.
