Azure offers a broad array of data services, individually they are compelling but choosing the right services and integrating them has always been tricky. Azure Synapse reduces this friction by bringing together the best of Azure's existing data services along with some powerful new features and making them play together nicely. You can use SQL to query the contents of your data lake either using provisioned resources (SQL Pools) or using serverless compute (SQL on-demand). It also comes with Spark notebooks, Azure Data Factory (Synapse Pipelines), Mapping Data Flows (ETL) and Power BI integration.
