How much RAM does HAProxy need?

Plan on 1 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 HAProxy plus your other workloads fit in RAM with room to spare.

Networking

A high-performance TCP/HTTP load balancer.

Balance and fail over traffic across backends with health checks and detailed stats.

HAProxy is rock-solid for load balancing self-hosted services and databases on your own hardware.

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Single C binary.
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 HAProxy its own database user with rights only on its own schema.
Reverse-proxy HAProxy 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 HAProxy patched — most self-hosting incidents are unpatched software.
