Fabric pulls everything that might be siloed in different places and unifies it under one SaaS wrapper. It brings together data engineering, integration, science, warehousing, BI analytics, and Synapse with one shared data foundation. This includes the Microsoft Fabric data warehouse capabilities, which combine the best elements of traditional data warehousing with modern cloud architecture.
OneLake: the heart of Fabric
At the core of Fabric is OneLake—think of it as OneDrive, but for all your company data. It’s a central lake where all your data lives, and every tool in Fabric can use it without having to copy anything, so there’s no need for duplication.
That’s not to say you lose control of your data structure. There are lots of options available, so you can still organise things in warehouses or lakes as needed—but it’s all in one place, accessible by every tool.

One experience for everything
Fabric brings together the big three: Power BI for dashboards, Synapse for analytics, and Data Factory for pipelines. But instead of bouncing between different portals, you get one workspace to do it all. It’s a SaaS-style experience you can access easily from the cloud.
While Microsoft Fabric vs Power BI isn’t an either/or choice (you’ll need a Power BI license to use Fabric anyway), knowing the difference is important. Similarly, Microsoft Fabric vs Synapse or Microsoft Fabric vs Data Factory comparisons miss the point—Fabric enhances these tools by unifying them rather than replacing them.
Using these all together under one roof means you’ll spend less time syncing tools, and duplicating data. It’s fast, and like most other things in the cloud, scales with your needs
