Cost management: cost analysis, budgets and budget alerts, Azure Advisor cost recommendations, reservations

Azure is billed on consumption, so costs can grow quietly: a forgotten test VM, an unattached disk or a public IP address left behind after a lab all keep charging. Microsoft Cost Management, available in the portal at no extra charge for Azure resources, gives you the tools to see where money goes, warn you before overspending and find savings. An administrator is expected to set these up and act on them, not just read the invoice at the end of the month.
