Daily anomaly detection across 5 dimensions (org, cloud account, resource group, resource, team) using percent deviation and z-score. Higher severity wins. Root cause analysis identifies instance resizes, new resources, reservation expiry, and schedule failures per anomaly. ZopNight applies cost anomaly detection to non-production across AWS, GCP, and Azure, measured against real usage. See it by cloud or by service below, and the discipline in [FinOps](https://zop.dev/learn/finops).

## Frequently asked questions

### Where should I start?

Start with the FinOps overview for the discipline that ties it together, then use the specific guide, cloud, or location page for the task you are on.

### Is production at risk?

No. Production is excluded by default; ZopNight acts only on the non-production resources you choose.

### What access does ZopNight need?

A read-only role to start. Discovery, cost reporting, and recommendations all run read-only, and you enable actions when you are ready.
