Is it capable of hosting XMPP, IRC, Email and a simple website altogether?
Yes.
Xmpp, irc, email and websites are all pretty small in terms of resource usage. Where you’ll have problems are with heavy compute workloads like 3d rendering, AI, 3d gaming (sorry, no crysis), and crypto mining. They all can be done on a rpi but not done well.
i run homeassistant, pihole, 2 projects of mine using NodeJS, nextcloud, a very simple static website and Nginx for some DNS customization like pointing nc.home to a specific port. My pi is a 4GB one and for now the used RAM is not even 1 GB. I run debian with no graphical interface
Slaps board of Pi this bad boy can fit so much fucking dust in it.
Username checks out.
How long is a piece of string?
It’s a great games console with archive.org retro games collection and retroPie installation.
If you want email, just setup Zoho free
And even if they can get around the port 25 block Gmail and other large email providers often block any emails coming in from a residential IP.
Mine runs OMV w/ Docker, Plex, Qbittorrent, Xteve as a virtual DVR for Plex feeding my IPTV into Plex, octobot, YouTube-dl web ui, various OSINT tools, MINIO… no issues what so ever, but I’m the only user.
To be fair I my 8vcpu vm struggles with transcoding, so I wouldn’t hold that against the pi. I got a little beelink box for jellyfin and it transcodes no issue with quicksync
MySQL, pihole, nextcloud and secure pastebin. Bunch of dotnet and python apps. Also running a notification service.
Is capable of seven
Sure it can, but it depends on what software you run and how much load you put on those services.
You can fit lots of stuff in 4gb of ram. Just pile on services till it starts running low.
Almost anything. Mine has 1GB of ram and it can do vpn, nginx proxy and other stuff just fine. Use dietpi.
I’m using for hosting lots of stuff in docker, as well as Plex direct streams. As long as it doesn’t have to transcode much its fine
