A company aims to run workloads efficiently in AWS, reduce operational overhead, and improve procedures. Which pillar of the AWS Well‑Architected Framework addresses these goals?

Operational excellence focuses on running workloads effectively, understanding their operational state, and continuously improving supporting processes and procedures to deliver business value. This includes automating changes, responding to events, and defining standards for daily operations. Reliability ensures a workload performs its intended function correctly and consistently. Performance efficiency focuses on using computing resources efficiently to meet system requirements and maintaining that efficiency as demand changes. Cost optimization is about avoiding unneeded costs and achieving business value at the lowest price. The company's goals of efficient workloads, reduced operational overhead, and improved procedures directly align with the principles of operational excellence.
