Case Study: a major U.S.-based educational organisation achieves peak exam uptime with LLInformatics' .NET modernisation and AWS migration support

a major U.S.-based educational organisation keeps peak exam season downtime at zero with LLInformatics

LLInformatics partnered with a major U.S.-based educational organisation to address the challenges of its mission-critical, 20-year-old education platform. The legacy system, built on outdated .NET libraries, suffered from performance issues, slow reporting, and a high risk of failure, which was especially critical with a peak exam season approaching that had zero tolerance for downtime. The client needed to stabilise the platform immediately without a disruptive full rewrite while also creating a path for a future AWS migration.

The solution from LLInformatics involved a targeted application modernisation and migration approach. They prioritised and refactored high-risk components, improved database performance and real-time reporting, and implemented automated monitoring. This incremental modernisation delivered immediate results: the platform operated with no downtime during the busy exam season, allowing students and administrators uninterrupted access. For the organisation, LLInformatics provided greater operational stability, improved system maintainability, and a controlled, phased path toward its planned AWS architecture.
