AWS module 9.1 Well-architected framework

Question 1

What is the main purpose of the AWS Well-Architected Framework, and how does it help cloud architects?

Answer 1

It provides best practices and a structured approach to design cloud systems that are secure, high-performing, resilient, and cost-efficient, helping architects evaluate and improve architectures.

Question 2

Why do cloud architects need to work with business decision makers when designing systems?

Answer 2

To ensure alignment between technical solutions and business goals, so the architecture delivers actual business value, not just technical performance.

Question 3

A system is high-performing but frequently fails under stress. Which Well-Architected pillar is being neglected and why?

Answer 3

Reliability — because the system cannot handle failures or recover effectively despite good performance.

Question 4

List the five pillars of the AWS Well-Architected Framework and explain what they collectively aim to achieve.

Answer 4

• Operational Excellence • Security • Reliability • Performance Efficiency • Cost Optimisation Together they ensure systems are well-balanced, efficient, secure, and scalable.

Question 5

A company focuses only on reducing costs and ignores performance and reliability. Why is this poor architecture according to the Well-Architected Framework?

Answer 5

Because the framework requires balancing all five pillars — focusing on cost alone leads to unstable, inefficient, and unreliable systems.
