Tailscale VPN Setup for Apache CloudStack

This document outlines the steps to install and configure Tailscale VPN, enabling users to deploy Apache CloudStack on a private network accessible from anywhere, even without public IP addresses.

Tailscale VPN is a mesh VPN that simplifies secure access to your networked devices. It allows you to connect your devices directly without the need for complex firewall rules or port forwarding.

Prerequisites

• A running instance of Apache CloudStack.
• Access to the terminal on the server where Apache CloudStack is installed.
