So what can you do with an 8GB Pi. Why would you need that much memory? Well let me tell you. Because Linux can run on such small amounts of memory you can actually press an 8GB Pi into service as a native Linux hypervisor. That is a server which can run multiple virtual machines. I would recommend using the Ubuntu OS for the Pi and the ARM version Ubuntu 20.04 for the guests I see Raspberry Pi OS has just gained native SATA support so you could just run your VMs on a SATA drive (don't store them on the MicroASD card) but I wanted to go a little further. If you have a shared storage medium like a TrueNAS you can use that to hold the VM files and have live migration. The upshot of all this I will be moving all my servers (monitoring, mail, search, dns, databases, nextcloud) into new VMs running on five (planned) Raspberry Pi 4 Model B 8GB.
