Deploy a Production AI Platform on AWS for $100/month

From seven broken Lambda functions to a production AI platform in 8 articles. That's the journey we've taken together. Functions that couldn't communicate, hit timeout walls, and left users staring at loading spinners. Now you get a complete platform that orchestrates complex workflows, streams real-time updates, and won't bankrupt your startup. This isn't a toy example. The architecture I'm about to show you serves 1,500+ requests daily, has survived 8 months in production, and handles everything from document analysis to multi-step research tasks. Time to deploy it. The Complete Architecture Before we dive into deployment, here's what we're building: - Content Classification The data flow: API Gateway receives requests, handles auth, enforces rate limits Gateway Lambda validates requests, checks budgets, routes to appropriate service ECS Agents orchestrate multi-step workflows using Lambda tools Lambda Tools perform specific AI tasks (summarize, extract, classify) DynamoDB tracks usa
