Operating internet-facing services in the home, in my opinion, requires a layer-3 managed switch so that internet traffic is 100% separated from home traffic, w/attendant DMZ to bridge home<-> internet-facing services safely.
L3 managed is the simplest method to contain a penetration to just the internet-facing devices (which is still pretty bad). Cloud hosting is more manageable, but you must watch the spend.
The biggest issue is a DDoS attack on the home network, which could impact internet-facing services and home clients (streaming TV, gaming, email, etc.).
Agree. Best to have that dedicated hardware, and a degree in network engineering first! Hah :)
tech waffle...
You might achieve network isolation without dedicated managed switches by: using prosumer routers or OpenWRT, with a Hypervisor like Proxmox, which support VLAN tagging. But this wouldn't save your home connection from a DDoS. To help with that, running public services behind CloudFlare seems to be one of the better choices, even our Lemmy hosts are using.If you're starting out, best keep internet facing home services private through a VPN, maybe ZeroTier or TailScale. Don't advertise them publically at all.
