The Challenge
EduHam needed to scale their learning platform from 5K to 50K+ concurrent students without performance degradation while maintaining real-time collaboration features.
Overview
EduHam partnered with us to transform their learning platform into a scalable system capable of serving 50K+ concurrent students.
Challenge
The existing monolithic architecture couldn’t handle rapid growth, leading to slow page loads, dropped connections during live sessions, and frustrated students.
Solution
We redesigned the architecture with CDN-first content delivery, distributed session management, and optimized real-time collaboration features.
Results
The platform now serves 10x more concurrent users with 85% student engagement and 200ms average response times.

Key Technical Decisions
CDN-first architecture
Tradeoff: Higher infrastructure cost
Why: Critical for global student base with low latency requirements
Redis for session management
Tradeoff: Additional service to maintain
Why: Needed for horizontal scaling of real-time features
