You're debugging a critical bug in the Example App. You need to see the raw data in the sale table to understand why the totals aren't adding up.
You fire up TablePlus or DBeaver, but you hit a wall. The database is (rightfully) in a private network.
How do you get in?
Do you temporarily open port 3306 to the world? Dangerous. Do you deploy a VPN server just for this? Expensive.
The answer is an SSH Tunnel.
You're building features for the Example App from your favorite coffee shop. You need to connect to the production database to debug a weird order issue.
But wait—you're on public Wi-Fi. Your IP address changes every time you reconnect.
Do you open port 3306 to the world? No. Do you constantly update your firewall rules with your new IP? Tedious. Do you set up a complex OpenVPN server? Overkill.
Enter Filess.io + Tailscale.
Your Example App store is growing. You have thousands of customers, which means you have thousands of emails, addresses, and purchase histories.
But there's a problem. Your database port (3306) is open to the entire internet.
Any script kiddie with a port scanner can find your server, start brute-forcing passwords, or exploit a zero-day vulnerability.
You need to lock it down, now.
