====== X2Go at the German Red Cross civil protection in Herne ======

The Red Cross is part of the civil protection services in Germany since decades 
and is mostly run by volunteers.
One of the numerous tasks people do there is ambulance service when damaging 
events occour or for planned public major events.

Such events require to quickly build up infrastructure in either unforeseeable 
locations, infrastructure that needs to provide services reliably for longer 
than a week, or both.

We provide the ambulance service for "Cranger Kirmes", a funfair taking place 
every year and lasting about 10 days.

Within this time, a control center is build up nearby the event temporarily, 
with a demand for reliable IT infrastructure.

Until 2017, client PCs were a mixture of donated general purpose PCs. As 
server, a modified standard PC was used, providing netboot via PXE and one 
"shared" hard drive via NFS.
The solution was built by hand and should be replaced by something that is 
well-known, supported by a community and has documentation available.
Moreover, there was demand for virtualization to be flexible and let the server 
provide additional services in the future.

Starting with 2018, the whole infrastructure was rebuilt from scratch. A 
rollable 19 inch rack was acquired, a rack mountable server has been donated 
and basically all supplementary hardware could be mounted permanently into the 
rack (e.g. router, PDU, switch, PBX).
To realize connectivity to the building's cabling, a patchpanel with RJ45 jacks 
on both sides was installed, so that the rack can be wired just as usual, and 
connections to the building's wiring can be established just by putting the 
rack next to the MDF und use a bunch of long patch cables.

Flexibility, scalability and ease of transport and setup were the main 
requirements in this project.

Thus, the rack-mount server runs Proxmox virtualization environment and a 
Debian-based linux installation providing the whole X2Go environment as one VM 
in it.
The mix of various PCs of different ages was discarded and replaced by a number 
of Fujitsu thin clients of the same model.

With the help of Proxmox, administrative tasks like distribution upgrades, 
backup/restore/snapshots can be performed by less experienced personnell and 
without fear of service outage.
In the long run, the classic PBX may be replaced by a Soft-PBX, and 
additionally, it is conceivable to provide this rack to nearby Red Cross 
organizations and to give them the possibility to let VMs for their needs run 
on the server alternatively.

Nevertheless, X2Go, in combination with X2Go-TCE provides an easy to setup 
remote desktop environment at no license cost. In our use case, management of 
clients is unnecessary and there is just one OS installation that needs to be 
maintained. With desktop-sharing, there is even a possibility of providing 
remote support directly without depending on solutions with a centralized 
infrastructure.
