[plug] Pi talk

[Oli Hills]

It really depends on usage.

1.  How large does the FS need to be?
  This depends whether you will need an external disk which on a Pi would be USB.  It's possible but personally I wouldn't trust a FS to a single USB disk with no backups.
2..  How much web traffic are you expecting?
  If it's anything commercial then run it on a cloud platform not from home.

I would offload the Router FW to a Ubiquiti security Gateway, it's a personal preference but I like my internet access to not be reliant on hardware that's used for anything else.

Once done you can happily run networking components such as DHCP / DNS on the Pi Including Pi hole alongside a low traffic webserver and other smaller services.  I like to treat Pi's and their disks as destroyable, so would configure it with Ansible and run all the services in docker.  That way if you ever need to recreate it you can pull a repo and hit the go button.

This is a low power unit (idles ~10W) and way more powerful than a PI with proper full speed GigE and USB3 if you want to hook up external disks. Nice thing too is you can expand/upgrade it with more ram or replace the internal disk etc... It's also tiny, about the same size as my NBN router!

I have a dav server, an asterisk PABX, internet facing web server, slave dns, email and a radicale calendar server plus a buildhost all in lxc on a single N2.  Everything including asterisk runs well on a gentoo-sources kernel and a re-purposed Gentoo aarch64 raspberry pi user-land from my old pi 3B.  An Odroid c4 will also work - note both of these have USB3 if you want to run extra usb network adaptors.  The n2 is running a bridge for LXC to the VLAN segmented networks while the C4 I have (odroid 4.14 kernel, gentoo aarch64 userland) is using 2 bridged USB 3 WiFi adaptors to vlans all without problems.  A major performance boost (at least 3x over an SD card in my tests) is had using the odroid eMMC storage, though the pi's have a sata hat available - I have tried using usb storage and usb networking together on both pies and odroids and its a serious no-no :) - corruption and really bad performance when busy).  The standard odroid OS is ubuntu and it can apparently also use raspian.

>>> Any pi less than a 4 will suffer from poor network performance (it all goes through an internal, under-powered USB2 hub), though I have used pi 1B's for all the above services in the past.  Going on my experience, a pi less than a 4 will do ok for a not very busy home server but wont do well for routing and a pi 4 should be better at networking whereas the more powerful odroid units will do it better, perhaps to small enterprise level with the right storage.  see https://www.hardkernel.com/shop/odroid-c4/ (the page for the older n2 i have uses a pi3 for the comparison, the newer N2+ is here https://www.hardkernel.com/shop/odroid-n2-with-4gbyte-ram-2/.)
