Cloud Migration for EdTech Platform
A cloud transformation engagement for an online education platform that had outgrown its legacy on-premise infrastructure. The platform serves 200,000+ students and educators with live video classes, assessment tools, and an adaptive learning engine. During exam seasons, traffic would surge 10x, causing outages and degraded user experience. We re-architected the entire platform from a monolithic PHP application into a cloud-native microservices ecosystem on AWS.
The Challenge
What We Faced
The client's monolithic PHP application was running on bare-metal servers with a single-point-of-failure database. During peak enrollment periods and exam seasons, the platform regularly crashed under 10x normal load, resulting in lost revenue and user trust. Deployments required 4-hour maintenance windows, and the team had no CI/CD pipeline, automated testing, or infrastructure-as-code practices. The migration needed to happen with zero downtime — the platform could not afford an outage during the academic year.
Our Solution
How We Solved It
We executed a phased migration strategy: first containerizing the monolith with Docker, then decomposing into 12 microservices (auth, video, assessments, analytics, etc.) deployed on AWS EKS. We implemented a strangler fig pattern to migrate services incrementally without downtime. The video streaming service was moved to AWS MediaLive with CloudFront CDN for global low-latency delivery. We built a full CI/CD pipeline with GitHub Actions, automated testing (95% coverage), and Terraform for infrastructure-as-code. Auto-scaling groups handle traffic spikes automatically.
