Authentication vs Authorization in AWS | System Design #systemdesign #aws #interviewprep

Authentication and Authorization are core security concepts in AWS system design, yet they are often confused in interviews.
In this breakdown, we explain how AWS verifies identity using Cognito, IAM, and STS, and how IAM policies control access to services like S3, Lambda, and DynamoDB.
This real-world AWS flow helps you understand how every request is authenticated first and authorized next — exactly how AWS evaluates permissions in production systems.
A must-know concept for backend, cloud, and distributed systems interviews.
