+# Services Exposed to the Internet - `wizzdom`
+
+Firstly, it's important to mention that Redbrick is currently split in 2 parts:
+- Redbrick 2.0 *a.k.a. "old redbrick"* (on `136.206.15.0/24`)
+- Aperture *a.k.a. "new redbrick"* (on `136.206.16.0/24`)
+
+## Old Redbrick
+- [**azazel**](../hosts/azazel.md) - `136.206.15.24`
+	- **OS**: Debian 10
+	- **Services**:
+		- primary ssh login box for users (see [Logging in](servers.md#Logging%20in))
+		- jump-box for admins
+- [**pygmalion**](../hosts/pygmalion.md) - `136.206.15.25`
+	- **OS**: Ubuntu 18.04 LTS
+	- **Services**:
+		- secondary ssh login box for users (see [Logging in](servers.md#Logging%20in))
+		- jump-box for admins
+- [**motherlode**](../hosts/motherlode) - `136.206.15.250`
+	- **OS**: NixOS 22.05
+	- **Services**:
+		- VM for [dcuclubsandsocs.ie](https://dcuclubsandsocs.ie)
+- [**hardcase**](../hosts/hardcase.md) - `136.206.15.3`
+	- **OS**: NixOS 22.05
+	- **Services**:
+		- `apache httpd`:
+			- websites from the webtree (including user webspaces):
+				- all user's websites `<user>.redbrick.dcu.ie`
+				- 
+			- legacy websites (pretty much anything that isn't dockerized)
+		- email (`postfix` and `dovecot`)
+		- mailing [lists](https://lists.redbrick.dcu.ie) (`mailman`)
+		- `*.redbrick.dcu.ie` also points here
+- [**zeus**](../hosts/zeus.md) - `136.206.15.31`
+	- **OS**: Ubuntu 18.04 LTS
+	- **Note**: this is a docker host, everything on here is in a container
+	- **Services**:
+		- [Wetty](servers.md#Logging%20in%20to%20Wetty) [wetty.redbrick.dcu.ie](https://wetty.redbrick.dcu.ie)
+		- [Admin API](api.md) [api.redbrick.dcu.ie](https://api.redbrick.dcu.ie)
+		- Secretary's email generator [generator.redbrick.dcu.ie](https://generator.redbrick.dcu.ie)
+		- [CodiMD](codimd.md) [md.redbrick.dcu.ie](https://md.redbrick.dcu.ie)
+		- all of this is routed through [traefik](traefik.md) as a reverse proxy
+- [paphos](../hosts/paphos.md) - `136.206.15.53`
+	- **OS**: Ubuntu 14.04 LTS
+	- **Services**:
+		- DNS ([bind](bind.md))
+
+## [Aperture](../aperture/index.md)
+In aperture, things are done a little differently than on the other network. Instead of having  a single host per service, aperture is configured to allow services to be allocated dynamically across all 3 servers using [nomad](../aperture/nomad.md), [consul](../aperture/consul.md) and [traefik](traefik.md).
+
+- [glados](../hosts/glados.md) - `136.206.16.4`
+- [wheatley](../hosts/wheatley.md) - `136.206.16.5`
+- [chell](../hosts/chell.md) - `136.206.16.6`
+- all 3 boxes are identical
+- **OS**: Debian 11
+- **Services**:
+	- simple `nginx` containers with the mascot of each server in aperture:
+		- [glados](https://glados.redbrick.dcu.ie)
+		- [wheatley](wheatley.redbrick.dcu.ie)
+		- [chell](https://chell.redbrick.dcu.ie)
+	- the [amikon.me](https://amikon.me) website for DCU AMS in an `nginx` container
+	- [timetable.redbrick.dcu.ie](https://timetable.redbrick.dcu.ie) a timetable that actually works, 10x better than the [official DCU timetable](https://mytimetable.dcu.ie)
+- **Notes**:
+	- all web traffic is routed through [traefik](traefik.md)
+	- all new services will be deployed here
+	- Most services here are deployed as docker containers but there's no reason you couldn't use any of the other [nomad drivers](https://developer.hashicorp.com/nomad/docs/drivers)
+	- For more information see redbrick's [Nomad repo](https://https://github.com/redbrick/nomad)
