We're talking here about a project to revisit and revitalise all aspects of the technology landscape provided and managed by CSG. Rather than ''lift-and-shift'' where existing applications and operational strategies are re-homed in a new hardware and operating system enviroment, this project looked at what CSG was doing to support CSE's teaching and research needs versus what was actually required. Thus it became a project..."

Early on, a decision was made that <code>conform</code> would be left behind and that all new servers and hosts set up in AWS would be managed some other way. This other way ended up being -- after a review of configuration management tools -- a split between <code>..." current
