 Azure Synapse is an analytics service that brings together enterprise data warehousing and Big Data analytics. It gives you the freedom to query data on your terms, using either serverless on-demand or provisioned resources—at scale. Azure Synapse brings these two worlds together with a unified experience to ingest, prepare, manage, and serve data for immediate BI and machine learning needs.
 
 Azure Synapse has four components:
 
 - Synapse SQL: Complete T-SQL based analytics – Generally Available
   - SQL pool (pay per DWU provisioned)
-  - SQL on-demand (pay per TB processed) – (Preview)
-- Spark: Deeply integrated Apache Spark (Preview)
-- Synapse Pipelines: Hybrid data integration (Preview)
-- Studio: Unified user experience.  (Preview)
