University of Alberta went from a pilot project of 13 courses in January 2011 to running all centrally supported courses (3600+) in Moodle in September 2012. Our central Moodle instance has seen more than 500,000 page loads and 24,000 unique visitors per day. This is a technical discussion of the challenges involved with providing this solution in large enterprise environment. We will discuss the architecture decisions, processes required to support this project, major incidents, resolutions and workarounds that were encountered during the first year and a half of the life of this project.
