Running it safely
Most MongoDB incidents are not exploits; they are an open port and no password. The image closes both, and the network firewall keeps it that way even if a config is later edited by mistake.
What the platform adds
A private network at no cost
Your application talks to the database over private IPs, and the database needs no public address at all.
A firewall in front of the machine
Rules enforced in the network, before traffic reaches the daemon.
Snapshot before a migration
Freeze the disk, run the migration, and put it back if it went wrong.
Memory first, then disk
MongoDB likes to keep the working set in RAM, so memory matters more than cores. Performance VPS puts the same tiers on NVMe, which is what a write-heavy collection notices.
From order to a working MongoDB
Pick MongoDB as the image
Performance VPS if writes are the workload.
Attach a private network
Your app server joins it and reaches the database privately.
Create an application user
Scoped to one database, not the admin account.
Point your connection string
At the private IP, never at the public one.
Straight answers before you deploy
Not by default, and that is deliberate. Reach it through an SSH tunnel, or open the port to your office range in the firewall.
Yes, across servers in the same region over the private network. Across regions you would need a tunnel.
