Interview Prep & End-to-End Examples
Cross-service scenario questions, and complete worked examples showing how everything you've learned combines into a real, production-shaped architecture.
End-to-End Example: A Containerized Microservices Platform on AWS
advanced~2hCombining ECR, ECS Fargate, ALB, RDS, and CloudWatch into a complete containerized microservices architecture — the natural next step once an application outgrows a single deployable EC2 fleet.
AWS Solutions Architect Interview Prep
advanced~2hCross-service scenario questions of the kind actually asked in AWS solutions architect interviews — the answers combine multiple topics you've already learned.
End-to-End Example: A Scalable Web Application on AWS
advanced~2hCombining EC2, Auto Scaling, ALB, RDS, S3, and CloudFront into one complete, production-shaped architecture — seeing how everything you've learned fits together.
End-to-End Example: A Serverless Web Application
advanced~2hCombining API Gateway, Lambda, DynamoDB, Cognito, and S3/CloudFront into a complete serverless architecture — no servers to manage at any layer.
Applying the Well-Architected Framework: A Worked Example
advanced~1.5hWalking through a real architecture review against all six Well-Architected pillars, showing exactly what kind of gaps a real review actually surfaces.
Design a URL Shortener on AWS
advanced~2.5hA worked system-design example mapping the classic 'design TinyURL' interview question onto real AWS services — DynamoDB for the core lookup, API Gateway/Lambda for the API, and CloudFront/Route 53 for global low-latency redirects.
Design a Chat Application on AWS
advanced~3hA worked system-design example for a real-time messaging app on AWS — API Gateway WebSockets for persistent connections, DynamoDB for message history, and the fan-out challenge of delivering a message to potentially many active connections.
Design a Video Streaming Platform on AWS
advanced~3hA worked system-design example for a Netflix/YouTube-style platform — S3 for storage, MediaConvert for transcoding into multiple resolutions, and CloudFront for adaptive-bitrate global delivery.
Design an Image Upload & Processing Service on AWS
intermediate~2.5hA worked system-design example for an image-heavy application — direct-to-S3 upload via pre-signed URLs, asynchronous thumbnail/resize processing via Lambda, and content moderation.
Design a Notification System on AWS
intermediate~2.5hA worked system-design example for a multi-channel (push/email/SMS) notification system on AWS — SNS as the fan-out hub, per-channel delivery via Pinpoint/SES, and user preference management.
Design an AI Chatbot on AWS
advanced~3hA worked system-design example for an AI-powered chatbot on AWS — Bedrock for the LLM, a RAG pipeline for grounding answers in your own data, and conversation-history management.
Design an E-Commerce Platform on AWS
advanced~3.5hA worked system-design example for a full e-commerce platform on AWS — product catalog, cart, checkout, inventory, and order processing, tying together nearly every service category covered elsewhere in this course.
Design a Banking System on AWS
advanced~3.5hA worked system-design example for a core banking/ledger system on AWS — the strict consistency, auditability, and compliance requirements that push this design toward RDS transactions, double-entry ledgers, and heavy encryption/audit logging.
