# Overview

> Configure CPU, memory, storage, and auto-scaling policies.

Specifications define the infrastructure requirements for your services. You can set these globally or override them per environment (e.g., smaller instances for `staging`, larger for `production`).

<div style={{ display: "flex", justifyContent: "center" }}>

</div>

## Auto-scaling

For `WEB_SERVICE` types, you can define fluid scaling based on traffic or resource pressure.

```yaml revolte.yaml theme={"dark"}
revolte:
  version: "1.0"
  project: Demo-Project
  appName: "demo-app"
  env:
    production:
      branch: main
      services:
        rid_1:
          type: WEB_SERVICE
          specifications:
            autoScaling:
              replica: { min: 1, max: 5 }
              utilization:
                cpu: { target: 70 }
                memory: { target: 70 }
```
