Indira Gandhi National Open University, India (IGNOU) is the world's largest open university in terms of student enrolments (2.5 + million approx.) for different programmes. Catering to the web based services to such large student fraternity is indeed a hard task. The systems and services were heavily biased towards proprietary corporations products, thereby, aggravating the quality of service to its intended audience. Moreover, virtualization was a blackbox to the IT department of IGNOU, until May 2009. Thereafter the entire networks and systems were stunned to see at least 3 Mediawiki sites , 2 Subversion server for in-house development team, 1 egroupware server on a single SUN Fire X 4140 powered by OpenVZ.
All the services are live with service downtime of 5 hours(due to electrical outage, ISP downtime) since May 2009 till date. That makes 99.91 % uptime.
Kudos to OpenVZ team for making this possible.
