How much RAM does MongoDB need?

Plan on 4 GB+ for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so MongoDB plus your other workloads fit in RAM with room to spare.

Data

The leading document database.

A flexible JSON-document store used by many modern apps, with rich querying and horizontal scaling.

Self-hosting MongoDB avoids managed-tier costs and keeps your documents on your own disk.

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Native packages or Docker.
3
Deploy the application
Follow the project’s official install guide for your distribution.
4
Enable HTTPS
Serve it on your own domain behind a reverse proxy with a certificate.
5
Back it up
Schedule a database dump plus a copy of any uploaded files to an off-box location.

Give MongoDB its own database user with rights only on its own schema.
Reverse-proxy MongoDB and terminate TLS at the proxy so certificates are managed in one place.
Take a VPS snapshot before major upgrades so you can roll back cleanly.
Keep MongoDB patched — most self-hosting incidents are unpatched software.
