Architectural difference: SQL Database = single PaaS DB; app backends. Managed Instance = near SQL Server compat; VNet; lift-and-shift. Synapse = analytics; MPP; Spark + SQL; warehouse/lakehouse. Workload: SQL DB for transactional; MI for migration; Synapse for analytics. Best practice: Choose by workload—transactional vs analytic.

Pro Tip

Red Flag: Using Synapse for OLTP. Pro-Move: 'We use SQL DB for apps; Synapse for BI—serverless SQL for ad-hoc, dedicated pool for batch.'
