Zero-Trust Architecture
Connecting distributed VPS nodes across AWS, DigitalOcean, and private clouds without exposing database ports to the public internet requires a secure private mesh overlay network.
- ▸Headscale WireGuard Mesh: Deploying a self-hosted control plane for Tailscale WireGuard VPN, enabling encrypted point-to-point IPsec tunnel connections.
- ▸Caddy Reverse Proxy: Automating ACME TLS/SSL certificate lifecycle management and proxying internal microservices without public port exposure.
- ▸Firewall Rules: Locking down cloud security groups to restrict all inbound traffic except WireGuard UDP ports and HTTPS port 443.
