Microsoft has made clear that Fabric is its strategic data platform investment. Synapse is not being deprecated, but new capabilities - Direct Lake, OneLake, Fabric IQ, Fabric Data Agents and the Rayfin backend SDK - are being built on Fabric, not Synapse. The practical question for most organisations is not "Fabric or Synapse?" in isolation. It is: should we migrate our Synapse investment to Fabric, and if so, when and how? ## What Azure Synapse Analytics Is Azure Synapse Analytics is Microsoft's unified analytics service, launched in 2020. It brings together several previously separate Azure services: - **Synapse SQL** - dedicated SQL pools for data warehousing, and serverless SQL for querying data lake files - **Synapse Spark** - Apache Spark for big data processing and machine learning - **Synapse Pipelines** - data orchestration and movement based on Azure Data Factory - **Synapse Link** - real-time integration with Dataverse, Azure Cosmos DB, and SQL databases Synapse is a well-established, production-grade platform. Many organisations have significant investments in Synapse dedicated SQL pools, Spark notebooks, and pipelines that are running reliably in production. ## What Microsoft Fabric Is [Microsoft Fabric](https://solv-systems.com/services/microsoft-fabric-data-platform-and-azure-services) is Microsoft's next-generation unified data platform, generally available since November 2023. It encompasses six workloads on a single SaaS platform: - **Data Engineering** - Spark notebooks, Lakehouses, Delta Lake - **Data Factory** - pipelines and dataflows - **Data Warehouse** - SQL-based warehousing - **Data Science** - ML experiments and models - **Real-Time Intelligence** - event streams and KQL databases - **Power BI** - embedded natively as the reporting layer All workloads share OneLake as a single unified storage layer. Data written by a pipeline is immediately available to Spark, SQL, Power BI Direct Lake, and Fabric Data Agents without copying or moving it. ## Key Differences ### Architecture **Synapse** is component-based. Each workload (dedicated SQL pool, Spark pool, serverless SQL) is a separate resource with separate configuration, scaling, and billing. Integration between components requires explicit data movement or sharing. **Fabric** is a unified SaaS platform. All workloads share OneLake storage and a single capacity-based billing model. Data written once is available to all workloads without copying. ### Billing **Synapse** uses resource-based billing. Dedicated SQL pools are billed hourly when running. Spark pools are billed per job. Serverless SQL is billed per terabyte processed. Costs scale with each resource independently. **Fabric** uses capacity-based billing. You purchase an F-SKU (ranging from F2 to F2048), and all workload usage is metered against that capacity. For organisations with mixed workloads across data engineering, Power BI, and analytics, capacity-based billing is typically more predictable. ### Power BI Integration **Synapse** connects to Power BI via dedicated SQL pool or serverless SQL endpoint. Semantic models use Import or DirectQuery. No Direct Lake. **Fabric** has Power BI as a native workload. Semantic models can use Direct Lake mode against OneLake tables - Import-level performance with near-real-time freshness. This is a significant capability advantage for Power BI-heavy organisations. ### AI Readiness **Synapse** supports Azure Machine Learning integration for ML workloads. No native Fabric IQ, Fabric Data Agents, or Copilot integration. **Fabric** has Fabric IQ, Fabric Data Agents, Microsoft 365 Copilot grounding, and Azure AI Foundry integration built natively - and Rayfin gives coding agents an application backend on the same platform. For organisations building AI on their data estate, Fabric's AI readiness is a material advantage over Synapse. ## When Synapse Still Makes Sense Despite Fabric being the strategic direction, remaining on Synapse is appropriate in some scenarios: - **Stable dedicated SQL pool workloads:** If your Synapse data warehouse is running reliably and meeting performance requirements, migration has a meaningful implementation cost that may not be justified immediately - **Existing Synapse Link integrations:** Synapse Link for Dataverse or Cosmos DB is stable and production-proven. Migration requires planning and testing - **Regulatory constraints on SaaS platforms:** Synapse has more direct infrastructure control than Fabric's SaaS model. For organisations with regulatory requirements that complicate SaaS adoption, Synapse may remain appropriate for specific workloads ## Migration from Synapse to Fabric For organisations planning to migrate, the typical sequence is: **Step 1 - Assess the current estate:** Inventory all Synapse workloads - dedicated SQL pools, Spark notebooks, pipelines, and link integrations. Identify which workloads migrate cleanly and which require rearchitecture. **Step 2 - Start with new workloads:** New data engineering and analytics projects go on Fabric from day one. This builds team capability and proves the platform without disrupting production Synapse workloads. **Step 3 - Migrate pipelines first:** Synapse Pipelines and Fabric Data Factory are architecturally similar (both are based on Azure Data Factory). Pipeline migration is typically the lowest-risk starting point. **Step 4 - Migrate Spark notebooks:** Synapse Spark notebooks migrate to Fabric Spark with relatively minor adjustments - primarily Lakehouse references and mount point configuration. PySpark code typically runs with minimal changes. **Step 5 - Migrate dedicated SQL pool workloads:** SQL pool migration to Fabric Warehouse requires the most planning - T-SQL dialect differences, distribution and partitioning strategy, and performance testing.
