Microsoft has unveiled Brain, an internal AI-based system that continuously monitors Azure's health and increasingly acts on its own: declaring outages, halting problematic rollouts, and notifying affected customers. As Azure CTO Mark Russinovich explained, Brain builds a real-time digital twin of the cloud and assesses service health using machine learning. Automatic notifications have markedly cut support tickets, as customers learn about a problem before they need to call. On top of Brain, the company is already running AI agents that help find and fix the cause of an outage faster.
