# Cloudflare Spectrum Skill Reference
|
|
|
|
## Overview
|
|
|
|
Cloudflare Spectrum provides security and acceleration for ANY TCP or UDP-based application. It's a global Layer 4 (L4) reverse proxy running on Cloudflare's edge nodes that routes MQTT, email, file transfer, version control, games, and more through Cloudflare to mask origins and protect from DDoS attacks.
|
|
|
|
**When to Use Spectrum**: When your protocol isn't HTTP/HTTPS (use Cloudflare proxy for HTTP). Spectrum handles everything else: SSH, gaming, databases, MQTT, SMTP, RDP, custom protocols.

## Decision Tree
|
|
|
|
**What are you trying to do?**
|
|
|
|
1. **Create/manage Spectrum app**
|
|
- Via Dashboard → See [Cloudflare Dashboard](https://dash.cloudflare.com)
|
|
- Via API → See [api.md](api.md) - REST endpoints
|
|
- Via SDK → See [api.md](api.md) - TypeScript/Python/Go examples
|
|
- Via IaC → See [configuration.md](configuration.md) - Terraform/Pulumi
|
|
|
|
2. **Protect specific protocol**
|
|
- SSH → See [patterns.md](patterns.md#1-ssh-server-protection)
|
|
- Gaming (Minecraft, etc) → See [patterns.md](patterns.md#2-game-server)
|
|
- MQTT/IoT → See [patterns.md](patterns.md#3-mqtt-broker)
|
|
- SMTP/Email → See [patterns.md](patterns.md#4-smtp-relay)
|
|
- Database → See [patterns.md](patterns.md#5-database-proxy)
|
|
- RDP → See [patterns.md](patterns.md#6-rdp-remote-desktop)
|
|
|
|
3. **Choose origin type**
|
|
- Direct IP (single server) → See [configuration.md](configuration.md#direct-ip-origin)
|
|
- CNAME (hostname) → See [configuration.md](configuration.md#cname-origin)
|
|
- Load balancer (HA/failover) → See [configuration.md](configuration.md#load-balancer-origin)
|
|
|
|
## Reading Order
|
|
|
|
1. Start with [patterns.md](patterns.md) for your specific protocol
|
|
2. Then [configuration.md](configuration.md) for your origin type
|
|
3. Check [gotchas.md](gotchas.md) before going to production
|
|
4. Use [api.md](api.md) for programmatic access
