I want to build a small, serverless engine that pulls brand-related data in real time and feeds it into an insights dashboard, but I’m missing a clear roadmap. The core signal I care about right now is customer reviews; however, I’d like the design to stay flexible enough to add Twitter, Facebook and Instagram mentions later without a full rewrite. What I need from you is a concise, step-by-step plan that shows exactly how to wire AWS Lambda into the overall flow—triggers, event sources, storage, streaming and analytics choices—so the system can ingest, process and surface insights the moment a new review appears. Think practical guidance rather than high-level theory: recommended AWS services, sample Lambda handler code, IAM considerations, deployment scripts (SAM or Terraform are both fine), and a small proof-of-concept that I can extend. Deliverables • Architecture diagram and narrative explaining each component • Deployment instructions or template I can run straight away • Example Lambda (Python or Node.js) that grabs a review, enriches it, and pushes the result downstream • Advice on scaling, cost control, logging/monitoring and GDPR-friendly data retention That’s it—give me the blueprint and a working skeleton so I can start iterating quickly.
