I self host on an NAS at home with a free Cloudfront CDN on top; it's really easy to do and for simple websites (including dynamic ones backed by an sqlite db) that don't receive excessive traffic, it works well and is almost free (since the NAS would be on in any case).

Of course it wouldn't work for all cases but I find it beats having a vps somewhere that can be taken down for no reason at all.

Os: Proxmox

Hardware: 4x Old decommed 19" dells on Ebay with plenty of DDR4 memory, HP Proliant G10+ are also good

Ups Eaton Pro

Gigabit Fiber Internet, which is more than enough. 10-50mbit can suffice for compute nodes too.

Bought ssds and m2 storage plus some spinning ols rust drives

Temp and humidity monitoring

Google Nest Protect smoke detector

TP link 16amp smart plugs on all, to have a control plane to turn it all off remotely

Workloads:

Most are LXC

Some Docker

KVM virtual machines

Zero trust: Some Cloudflare

Tailscale

Proxmox backup server to back it all up, lots of retention

Monitoring:

Deployed remote uptime monitoring on fly.io

Read and experiment a lot Hang out on /r/homelab /r/homedatacenter and /r/selfhosted for learning, community and inspiration

I have space in my house, using up half a shed I have 1 gbit fiber
