Microservices Architecture for Modular EdTech File Processing

If you’re building or scaling a learning management system, you’ve probably seen this: exam week arrives, thousands of students upload assignments at once, and the system starts to slow down or crash. Video processing delays document uploads. A failed virus scan blocks everything behind it. One bad file affects other students. When everything runs inside one big system, a small problem can impact everyone. The fix isn’t just better servers. It’s a better architecture. With a microservices approach, each task runs independently. You can scale specific parts, prevent failures from spreading, and meet strict education compliance requirements more easily. This guide is an architectural blueprint for technical decision-makers who need to build that system. Key Takeaways EdTech platforms need a smarter architecture to handle deadline spikes, many file types, and strict privacy rules. Break the system into six clear services: Ingestion, Validation, Transformation, OCR, Metadata, and Delivery.
