About This Architecture

Student Assessment Platform on AWS Mumbai deploys a three-tier architecture with Route 53 DNS, NGINX reverse proxy, and dual portal services (Student and Admin) routing through a unified Backend API Layer. The Assessment Engine, Proctoring Orchestrator, and Background Workers process requests, leveraging PostgreSQL, Redis, MongoDB Atlas, and Amazon S3 for state management and artifact storage. Proctoring integrates real-time video/audio capture with a Dedicated GPU Server running YOLO11n, Google MediaPipe, and Silero VAD for biometric verification, while external AI services (Speechace, OpenAI GPT-4/GPT-5, ElevenLabs) handle specialized inference without storing client data. Jenkins CI/CD, AWS Secrets Manager, and automated monitoring ensure secure, compliant operations with data residency in ap-south-1.

How do you architect a secure, proctored student assessment platform on AWS with real-time biometric verification and AI-powered grading?

This diagram shows a production AWS architecture in ap-south-1 with Route 53 DNS and NGINX reverse proxy routing student and admin traffic to separate portal services. The Proctoring Orchestrator captures live video/audio, sends streams to a Dedicated GPU Server running YOLO11n and MediaPipe for face/pose detection, while Speechace and OpenAI GPT-4 handle voice and content analysis—all without sto
