The Challenge

What They Were Facing

A breakdown of major operational friction points prior to our team's integration and custom build.

An online school suffered from database load spikes and site crashes during exam schedules. We refactored their video and testing servers to run on auto-scaling serverless nodes and configured an edge CDN cache, ensuring site stability for 25,000+ simultaneous test takers.

  • !Exams with 10,000+ simultaneous users caused database crashes.
  • !High bandwidth bills from raw video hosting.
  • !Slow mobile load times for users in tier-3 cities.

We had zero visibility on our daily logs, and errors were cropping up in invoicing sheets regularly. We had to fix it before expanding our footprint.
