Facilities asks which AWS Well-Architected Framework pillar focuses on reducing the environmental impact of cloud workloads. Which pillar should the team cite?
Select an answer to reveal the explanation.
Short Explanation
Picture a green-building checklist for software, not just for the city hall HVAC. Sustainability is the Well-Architected pillar that asks how workloads use energy and materials, and how to shrink that footprint over time. Cost Optimization cares about dollars, Performance Efficiency about speed and fit, and Operational Excellence about runbooks — none of those is the environmental-impact pillar.
Full Explanation
The AWS Well-Architected Framework includes Sustainability as a named pillar that guides teams to minimize the environmental impacts of cloud workloads. Practices under that pillar include efficient resource use, right-sized capacity, and designs that reduce waste over the workload lifecycle. Cost Optimization addresses spend efficiency, Performance Efficiency addresses selecting and scaling resources for performance needs, and Operational Excellence addresses how teams operate and improve systems — so they are related design concerns but not the pillar that Facilities is asking about.
