In short, you can boot your Raspberry Pi OS remotely over network from a central server that is configured to support PXE booting. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP. The Preboot eXecution Environment, PXE (most often pronounced as /ˈpɪksiː/ pixie, often called PXE Boot/pixie boot.) specification describes a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients.

I am going to use this to host my websites and data. SD cards always have speed limitation and there are chances SD card maybe corrupted during incidents such as power interruption. Running Raspberry Pi 4 with SD card (a good fast SD card) is fine, if speed and resiliency is not a concern.
