Modern cloud costs on AWS and GCP scale exponentially. For solo founders and engineering teams, self-hosting on **Coolify** provides 90% of AWS/Vercel developer experience at less than 5% of the bill.

In this operational guide, we dissect production Coolify architecture, automated Git webhook rebuilds, and resource-bounded container management.

## 1. Coolify Architecture Under the Hood

Coolify operates as a control plane orchestrating a local Docker daemon and Traefik reverse proxy:

```
┌──────────────────────────────────────────────┐
│          Coolify Control Plane (Port 8000)   │
├──────────────────────────────────────────────┤
│  • Traefik v3 (Dynamic Ingress & Auto-SSL)   │
│  • Automated GitHub / GitLab Webhooks        │
│  • Multi-Tenant Environment Isolation        │
└──────────────────────┬───────────────────────┘
                       │
       [Docker Engine & Alpine Containers]
```

## 2. Hardening Traefik Ingress & TLS

By default, Coolify configures Traefik with automated Let's Encrypt certificates. In high-traffic deployments, protect against denial-of-service by enabling container-level rate limits:

```yaml
labels:
  - "traefik.http.middlewares.ratelimit.ratelimit.average=100"
  - "traefik.http.middlewares.ratelimit.ratelimit.burst=50"
```

<Callout type="tip" title="Zero VPS RAM Secret">
Pairing Coolify with pre-rendered Astro static sites running inside Alpine Nginx drops per-app RAM consumption to just 8 MB. You can host 20+ micro-sites on a single 4GB VPS without touching swap memory.
