A brief overview of the servers.

Open Source Platforms

We have a number of open source software platforms running on a Dell Quad Core Server with 16Gb Ram and 1Tb Raid Hard Drives

Ubuntu Server

We have Ubuntu server that is capable of running virtual instances. It has redundant drives and power, however only a single fixed IP address and support is adhoc. If you need 24/7 uptime - this is not for you. If you want a place to test something before deploying to a bigger better platform this may be helpful. Automation

We have a docker running - which provides a platform for integration between various web objects, at the moment this is not eternally accessible. That may be a possibility in the future.

R Studio Server

We have an R Studio Server running R 4.x - if you have a data analysis application that needs R but can’t install it locally this may be useful. Much of what we post here will be about succesful implementation of R code.

Uses include

Shiny Server

We have a Shiny Server. Access is behind a password. Shiny is quite new to us, so we aren’t quite sure what its main applications could be. We are using it for a learnR application.

Gaucamole Server

We have a mothballed implementation of Gaucamole. If you need remote access to a linux GUI we may well be able to bring this back out of mothball.

Mail Server

We have a Dovecot IMAP mail server, with a webmail front end, which is mostly for private use, however may have a role in maintaining integrations.

Technical Stuff

SSL Certificates

All our servers support SSL through a common certificate *, which is renewed regularly through Lets Encrypt


All inbound traffic is routed through a single server point which is running nginx, and can (and does) re-direct traffic to other servers within the virtual cluster. It could also redirect traffic outside the cluster. This redirection is seamless and secure.
