How much RAM does Zabbix need?

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

What stack does Zabbix run on?

Server + frontend + DB (MySQL/Postgres).

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

Networking

Enterprise-class monitoring for servers and networks.

Collect metrics, define triggers and alert on infrastructure of any size, all self-hosted.

Zabbix scales from a single box to thousands of hosts, and self-hosting avoids per-device licensing.

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Server + frontend + DB (MySQL/Postgres).
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 Zabbix its own database user with rights only on its own schema.
Reverse-proxy Zabbix 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 Zabbix patched — most self-hosting incidents are unpatched software.
