The Azure SRE Agent is designed to streamline incident response, improve service uptime, and cut operational costs, allowing Site Reliability Engineers to focus on higher-value tasks. Why’s it interesting from a licensing perspective? It’s the first Azure-hosted autonomous Agent that’s billed via a new measure – Azure Agent Units or AAUs. The Azure SRE Agent continuously monitors in the background incurring charges of 4 AAUs an hour and then, when issues are detected, billing is 0.25 of an AAU for every second the Agent is engaged on a task.
