If needed, a larger disk can be added on demand later. The same for memory capacities. The current hosting cost is about 170 EUR/month.
* **Server configuration** :
> * Operating sytem: Debian 12
> * ProxMox Virtual Environment (PVE 8.2)

> > * community.youth-care.eu > campus-yc.rio20.net (Moodle/Iomad in production mode)
> > * dev.campus.youth-care.eu > dev.campus-yc.rio20.net (Moodle/Iomad in development mode)
> > * meet.youth-care.eu > bbb-yc.rio20.net (Big Blue Blutton) https://meet.youth-care.eu
> > * video.youth-care.eu > peertube-yc.rio20.net (Peertube)
> > * kb.youth-care.eu > knowledge-base-yc.rio20.net (Redmine) https://kb.youth-care.eu
