Workshop

IELTS Self-Learning Web System - AWS Infrastructure Workshop

Overview

This comprehensive workshop guides you through building a production-ready AWS infrastructure for the IELTS Self-Learning Web System. You will learn how to deploy a highly available, scalable, and secure web application using modern AWS services and best practices.

The architecture implements an active-passive Multi-AZ deployment pattern on Amazon ECS, with a serverless AI service layer for intelligent assessment and content generation.

What You Will Build

By completing this workshop, you will have deployed:
