Cole Tramp's Microsoft Insights

As more organizations seek greater flexibility and performance in their data pipelines, Microsoft's Dataflow Gen2, now part of Microsoft Fabric, offers compelling improvements over the legacy Dataflow Gen1 experience. If you’ve been using Gen1 for Power BI transformations, it may be time to consider moving your workloads.

Let’s explore the differences, the advantages of Gen2, and how to migrate efficiently using the import/export method.

Understanding the Evolution: Dataflow Gen1 vs Gen2

Dataflow Gen1 was introduced as part of Power BI to help users perform ETL (Extract, Transform, Load) operations with ease using Power Query. It allowed for cloud-based data prep at scale - but it came with several limitations that began to restrict enterprise use cases as demand grew.

As organizations strive to become more data-driven, many face a common challenge: how to modernize data workflows without disrupting existing operations. Microsoft’s introduction of the Azure Data Factory (ADF) Item (Mount) capability within Microsoft Fabric provides a compelling answer. This integration offers a strategic bridge between legacy ADF implementations and the modern data stack enabled by Fabric, delivering both immediate and long-term business value.

Bridging Legacy and Innovation

The ADF Item (Mount) feature allows businesses to bring their existing Azure Data Factory pipelines into the Microsoft Fabric workspace without requiring migration or redevelopment. Rather than starting from scratch, teams can simply “mount” their pipelines into Fabric, allowing them to view, manage, and even edit those pipelines from within Fabric’s unified interface. This seamless integration means organizations can begin to adopt Fabric’s modern capabilities while maintaining the stability and familiarity of their current ADF setup.

In an era where data powers decision-making, products, and customer experiences, the stakes for analytics platforms have never been higher. Enterprises need more than just performance, they need platforms that are dependable, recoverable, and built to withstand disruption. That’s why Microsoft Fabric, the unified analytics platform for modern data estates, puts reliability at its core.

As detailed in Microsoft’s official reliability guidance, Fabric’s architecture and operational model are designed to deliver continuous service, protect against failure, and ensure business continuity for mission-critical workloads. But what makes this reliability possible?

Built on a Global Foundation: The Azure Backbone

The story of Fabric’s reliability begins with its infrastructure. Microsoft Fabric is built directly on Azure’s global backbone, benefiting from the same cloud infrastructure that powers services like Microsoft 365 and Azure itself. This gives Fabric access to a geographically distributed, enterprise-grade cloud platform with redundant compute, storage, and networking capabilities across continents.

In the evolving landscape of data management, Microsoft has unveiled a bold vision with OneLake, a central pillar of Microsoft Fabric. Often described as "the OneDrive for data," OneLake aims to simplify, unify, and accelerate data access and collaboration across the entire enterprise, regardless of tool, format, or platform.

What Is OneLake?

OneLake is a single, unified, multi-cloud data lake built into Microsoft Fabric. It acts as a central storage layer for all data workloads, seamlessly integrating with tools like Power BI, Synapse, and Data Factory. Just like OneDrive abstracts file storage for documents, OneLake abstracts and simplifies access to structured and unstructured data at scale.

With OneLake, organizations no longer need to manage multiple data lakes for different services or business units. Instead, they get a single logical lake for the entire Microsoft tenant, providing consistent access control, governance, and performance optimization out-of-the-box.

Key Features

With the rise of Microsoft Fabric as a next-generation data platform, many organizations that currently rely on Azure Synapse Analytics are wondering how the two platforms compare and what the future holds. Are they competing products? Is Synapse being phased out? And if you're already invested in Synapse, can you migrate to Fabric?

The short answers: they're built differently, Synapse is here to stay (for now), and some migration paths do exist. Let’s explore what that means in practice.

A Tale of Two Platforms

At a high level, both Microsoft Fabric and Azure Synapse aim to solve the same fundamental challenge: helping organizations turn raw data into actionable insights. But the way they go about it is fundamentally different.

Microsoft has officially announced that Copilot in Power BI is now supported across all Microsoft Fabric capacities, marking a major milestone in the integration of generative AI with business intelligence. This expansion empowers users to harness AI-driven insights and report generation, no matter what capacity their organization is operating within, eliminating prior limitations and making this powerful feature universally accessible within the Fabric ecosystem.

Although this update rolled out a few months ago, it's a game-changing shift that still deserves attention today especially for organizations now fully embracing Copilot’s capabilities.
