How much RAM does ClickHouse need?

Plan on 8–16 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 ClickHouse plus your other workloads fit in RAM with room to spare.

2
Install the stack
Install Single binary + native/web UI.
3
Deploy the application
Follow the project’s official install guide for your distribution.

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 ClickHouse its own database user with rights only on its own schema.
Reverse-proxy ClickHouse 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 ClickHouse patched — most self-hosting incidents are unpatched software.
