Question
Which design principle is included in the operational excellence pillar of the AWS Well-Architected Framework?
A. Create annotated documentation
B. Anticipate failure
C. Ensure performance efficiency
D. Optimize costs
Answer
A. Create annotated documentation
Explanation
Create annotated documentation supports operational excellence by improving understanding and management of workloads.
The Operational Excellence pillar of the AWS Well-Architected Framework focuses on designing, operating, and evolving workloads effectively to deliver business value. It emphasizes continuous improvement of processes, people, and technology. Among its core principles is “Create annotated documentation”, which ensures that teams have clear, accessible documentation to support operations and decision-making.
Annotated documentation is critical for
- Enabling effective collaboration across teams by providing context and clarity.
- Supporting operational procedures with detailed, actionable insights.
- Facilitating troubleshooting by offering a well-documented history of system behaviors and configurations.
This principle aligns with the broader goal of operational excellence to ensure that workloads are well-understood and can be managed efficiently at scale. Other design principles in this pillar include performing operations as code, anticipating failure, and refining operational procedures frequently.
Why Not the Other Options?
B. Anticipate Failure: While this is a design principle for operational excellence, it is not the correct choice here as the question specifically asks about “Create annotated documentation.”
C. Ensure Performance Efficiency: This belongs to the Performance Efficiency pillar, not Operational Excellence.
D. Optimize Costs: This is part of the Cost Optimization pillar.
