# Narwhal Cloud - Full Specifications & Lab Manual

> Complete summary of Narwhal Cloud NAT VPS platform, features, and key documents for AI consumption.

Narwhal Cloud is an experimental NAT VPS (natvps) platform offering low-overhead virtualization (LXC, Podman) and hardware-level isolation (KVM). By utilizing Network Address Translation, multiple instances share a single public IPv4 address, significantly reducing hosting costs.

## Core Technology Stack & Architecture

1. **Lightweight Engines (LXC & Podman)**:
   - Near-native performance density.
   - Ideal for light databases, tools, script execution, and web development.
   
2. **KVM Isolated Engines**:
   - Hardware-level isolation.
   - Dedicated kernels, ideal for custom network topologies or raw performance validation.

3. **Billing Model**:
   - Fully daily billing (pay-as-you-go).
   - No contract, spin up or delete nodes instantly.

## Frequently Asked Questions (FAQ)

### What is a NAT VPS?
A NAT VPS (often referred to as a shared IP server) is a virtual private server that shares a public IPv4 address using Network Address Translation (NAT). Users get dedicated system resources along with private port mappings. Services are exposed via custom port forwarding rules.

### Can it be used for production?
No. Narwhal Cloud is optimized for latency testing, script playgrounds, and geeks. It does not provide high-availability SLAs for critical production services.
