Azure Data Explorer

Azure Data Explorer is a managed analytics service from Microsoft for log, telemetry and time-series data. Data is queried with the Kusto Query Language and with T-SQL, and the service includes built-in time-series functions. It is also categorised as an analytical or warehouse product. The service is proprietary and available only as a managed cloud service on Azure, so there is no self-managed option and no separate commercial edition. No release version or release date is stated for it as a product, although the overview page in Microsoft's documentation is dated 23 July 2026. Pricing has not been checked here, so buyers should consult Microsoft's Azure pricing page for current charges before planning a deployment. Azure Data Explorer suits organisations that already run on Azure and want to analyse large volumes of logs and telemetry using a query language designed for exploring such data, and that are content to depend on a single cloud provider. Because it is closed and runs only in Azure, it is less suitable for teams that need to keep the option of moving the same database to another cloud or to their own servers.
