During academic assessments, the stability and user-friendliness of IRIS is paramount. The team undertook the crucial steps to achieve this goal. The IRIS user interface was thoughtfully designed to streamline the process into three simple steps:

  • Selecting input devices
  • Entering student information
  • Granting browser permissions

Once these steps are completed, the proctoring process commenced, and upon finishing the assessment, the session was automatically uploaded to the IRIS servers.

To guarantee optimal performance and accommodate the fluctuating demands during exam periods, AWS was selected as the ideal cloud hosting provider. Its capabilities around scalability, reliability, and cost-effectiveness made it the perfect fit. We then proceeded to configure auto-scaling capabilities to efficiently handle sudden surges in activity.

Considering the critical nature of data security and risk management, automated database backups and extensive logging mechanisms were implemented in the IRIS project. This ensured data integrity and provides comprehensive support in case of any unforeseen issues.

Extra measures were implemented to guarantee the safe collection of session files on the IRIS servers. Offline mode and an automated retry process were put in place to ensure that no data was lost, providing users with added confidence in the system's reliability.

By prioritising stability, user experience, scalability, and reliability, the IRIS platform is effectively equipped to handle the pressures of assessment periods, ultimately serving students and educators alike with a dependable and efficient assessment solution.
