University of Oxford - Preparing a new system for an admissions peak of 3,500+ applications
Capacitas Ensures The World's Top University Manages Its Admissions Peak
Situation
When you have just been recognised as the top university in the world, you need to do all you can to protect that position. The Times higher education world university rankings 2016/17 placed the university of oxford in the number one position – the first time that a UK institution has won this accolade.
As one of the world’s top universities, the volume of students applying for postgraduate study at the University of Oxford has always been very high, with a large number of applications pouring through the admissions website just before the January admissions deadline.
“Capacitas provided us with the information we needed to ensure that our services operated effectively during our busiest deadline.”
David White, Director of Student Systems
The Challenge
This time around the University was relying on a new system to manage applications, so there was understandable apprehension about how well it could handle peak demand. Anxious to avoid frustrating the applicants - due to long response times or website failure - the University called on a trusted supplier, Capacitas, to prove the expected peak demand could be met.
Solution
In October, Capacitas undertook a structured risk assessment of the system architecture and software. A key risk was the uncertainty around the demand profile on the peak day. Capacitas addressed this risk by examining the University’s historical data to model and extrapolate future demand volumes. Several demand scenarios were then modelled to size the IT infrastructure needed to service the demand. As the January admissions deadline approached, Capacitas recommended increasing server memory and CPU processing power.
Results
On the final day of application submissions, demand was even higher than the University had expected. Members of the in-house IT team monitored events and found that the system worked exactly as the Capacitas model had predicted. Over 3,500 applications were processed by the system, with a peak of 750 in one hour.
Prior to the risk analysis and modelling of the admissions deadline, capacitas had undertaken a significant amount of performance testing, covering a six to eight-month period, resulting in five critical risks being identified that required software and configuration fixes.
Final Day of Application Submissions
Demand was even higher than the university had expected. The system worked exactly as the capacitas model had predicted.
“Capacitas have a proven systematic approach to performance and capacity management, they understand the university and i knew i could be confident that the performance risks identified would be mitigated prior to the postgraduate admissions deadline
Nigel Emm, IT Services Head
