KQL

KQL is the query language that turns Azure Resource Graph into your most powerful operational tool. For administrators managing thousands of resources across dozens of subscriptions, KQL queries become the authoritative source of truth—more reliable than the Azure portal, more current than your CMDB, and more useful than any inventory spreadsheet. Azure Resource Graph stores metadata about every resource in your tenant, and KQL unlocks it. Real KQL mastery means building queries that join cost data with tag metadata, correlate resource configurations across subscriptions, and generate compliance reports that auditors actually accept. It means understanding how to query virtual machine inventory, analyze storage account configurations, track policy compliance, and identify security vulnerabilities—all without clicking through the Azure portal 10,000 times. When you need to answer questions like "show me every VM without a CostCenter tag" or "find all storage accounts with public network access enabled," KQL is the only tool that works.
