Build production AWS foundations
Start with architecture boundaries, IAM, observability, failure handling, cost, and cleanup—the parts that determine whether a demo survives production.
Choose a structured pathStart learning
Choose a problem. Follow a path. Prove what you learned.
InfraTales is organised for engineers who want production judgement, not a pile of disconnected tutorials. Begin with one path and complete the practice before moving to the next lesson.
Pick your starting point
What are you trying to do today?
Compare architecture options
Use decision-led guides when you need to choose between services, justify a trade-off, or document why one design fits better than another.
Browse architecture decisionsUnderstand a production failure
Follow the signal, failure edge, likely cause, and response. Every useful diagnosis should leave you with a stronger runbook.
Browse failure breakdownsHow each lesson works
One consistent learning contract.
Answer
Get the recommendation and its conditions immediately.
Reason
Understand the system model, trade-offs, and rejected alternatives.
Practise
Build, diagnose, or work through a safe decision exercise.
Prove
Use expected evidence and a knowledge check to confirm the outcome.

S3 to Lambda Through EventBridge: Cost, Audit, and Routing Trade-offs
Choose direct S3 events or CloudTrail data events for EventBridge without paying for an audit path your Lambda trigger does not require.
AWS CodeDeploy on EC2 Auto Scaling: ALB Health, Rollback, and Safe Releases
Wire CodeDeploy, an Auto Scaling group, and an ALB so new instances receive the right revision and failed releases stop and roll back.
AWS Web App on Fargate, Aurora, and CloudFront: Production Boundaries That Matter
Design the traffic, network, database, secret, scaling, and cost boundaries for a Fargate web application instead of stopping at deployment.
