DevOps for a municipal API wants the Well-Architected pillar that emphasizes automating changes and learning from day-to-day operations. Which pillar matches that emphasis?
Select an answer to reveal the explanation.
Short Explanation
Automating the boring change steps and reviewing what broke last Tuesday is classic ops craftsmanship. Operational Excellence is the pillar that pushes teams to automate changes, observe what happens, and refine how they work. Cost, performance, and sustainability pillars care about money, speed/fit, and environmental impact — not that learning-and-automation loop first.
Full Explanation
Operational Excellence includes practices such as performing operations as code, making frequent small reversible changes, refining procedures from operational events, and using observability to understand workloads. Cost Optimization focuses on spend efficiency, Performance Efficiency on selecting and using computing resources effectively, and Sustainability on environmental impact. For a municipal API team prioritizing automation of changes and learning from operations, Operational Excellence is the correct pillar.
