AWS Cloud Architecture and Design Principles Flashcards

Which AWS Well-Architected Framework pillar focuses on protecting data, systems, and assets through risk assessments and mitigation?

Answer: Security

The Security pillar of the Well-Architected Framework covers identity management, detecting incidents, protecting data, and automating security best practices.

Which AWS Well-Architected pillar focuses on the ability of a system to recover from failures and meet demand?

Answer: Reliability

The Reliability pillar addresses designing systems that can recover from infrastructure failures, scale to meet demand, and mitigate disruptions.

What is the purpose of deploying resources across multiple Availability Zones in AWS?

Answer: To improve fault tolerance and eliminate single points of failure

Multi-AZ deployments ensure that if one data center fails, your workload continues running in another AZ, eliminating single points of failure.

What does 'designing for failure' mean in AWS cloud architecture?

Answer: Building systems that assume component failures will happen and remain operational anyway

Designing for failure means architecting systems with redundancy and auto-recovery so they remain available even when individual components fail.

Which architectural pattern decouples application components so they can scale and fail independently?

Answer: Loose coupling

Loose coupling uses queues, APIs, or events to separate components, so failures or scaling needs in one part don't directly impact others.

Which AWS service helps implement loose coupling by allowing components to communicate asynchronously via message queues?

Answer: Amazon SQS

Amazon SQS (Simple Queue Service) provides a managed message queue that decouples producers and consumers, enabling asynchronous and fault-tolerant communication.
