Azure vs. Fabric: The Ultimate Data Factory Showdown 

Introduction to Azure vs. Fabric

In the modern era of data reliance, managing the flow of information across diverse sources is crucial for businesses. To address this need, Microsoft offers two powerful solutions: Azure Data Factory (ADF) and Fabric Data Factory. This article aims to compare the two tools, highlighting their key differences, benefits, and limitations, to help you make an informed decision based on your specific data management needs.  

What is Azure Data Factory (ADF) 

Azure Data Factory (ADF) is a tool that helps you move and transform data from different places and various sources, and then publish the data to the desired destination. It allows you to create, schedule, and orchestrate data workflows without the complex coding, all in a seamless and automated manner. 

What is Fabric Data Factory (FDF) 

Fabric Data Factory (FDF) is a newer tool in Microsoft’s data management lineup. It works closely with Microsoft’s Power Platform to create a seamless environment for data integration, transformation, and management. FDF simplifies building data pipelines by using the features of Power Query and other Power Platform tools, making the entire process more efficient and user friendly. 


Key Differences 

Let’s see the main differences between Azure Data Factory and Fabric Data Factory. 

  1. Fabric Data Factory allows you to create data pipelines by connecting various unified platforms like Lakehouse and Data Warehouse. This means you can easily move and transform data across different systems within Fabric.
  2. Fabric Data Factory‘s Dataflow Gen 2 is directly linked with Power Query, which enables advanced data transformation and cleansing when connecting data sources. This powerful feature is not available in Azure Data Factory. 


3. In Fabric Data Factory, you have access to new features like Teams, Office 365 Outlook, and KQL Database. Office 365 Outlook and Teams can be easily used for notifications. For example, you can set up notifications in your data workflows to send messages to Microsoft Teams or emails through Office 365 Outlook. These features are not available in Azure Data Factory. 


4. Azure Data Factory uses datasets to define data sources and destinations in pipelines. Fabric Data Factory does not use the concept of datasets. Instead, Fabric Data Factory focuses on more modern concepts like Lakehouse and Warehouse for data storage and processing. 

5. Linked services in Azure Data Factory are configurations for connecting to external data sources or destinations. Fabric Data Factory simplifies this with connections, which serve a similar purpose but are easier to set up and manage within the Fabric environment. 

6. Fabric Data Factory has fewer triggering options compared to Azure Data Factory. Currently, only scheduling is available; other options like event-based triggers and tumbling window triggers are not yet supported. 


7. Azure Data Factory (ADF) uses Integration Runtimes (IR) to manage data movement and processing across different environments. There are three types of IR in ADF: Azure Integration Runtime, Self-hosted Integration Runtime, and Azure-SSIS Integration Runtime. Fabric Data Factory (FDF), on the other hand, does not have Integration Runtimes. Instead, it uses an on-premises data gateway to connect to on-premises data sources. The data gateway acts as a bridge, providing a secure connection between on-premises data sources and cloud services. 

8. Azure Data Factory offers more control over the CI/CD pipeline because you can manually configure and manage the deployment process. This means you have more flexibility but also more responsibility for setting up and maintaining the pipeline. Fabric Data Factory, on the other hand, is designed to be more CI/CD friendly. The entire workspace is connected to a version control system (like Git), which means that changes made to the data factory are automatically tracked and can be easily deployed using CI/CD tools. 


In Fabric pipelines, you can use the ‘Save as’ feature to easily make copies of existing pipelines for different development needs. This is handy for making slight changes or trying out new configurations. In Azure Data Factory, the ARM feature serves a similar purpose, allowing you to create copies of your pipelines. 


The Fabric Monitor Hub makes monitoring easy by bringing all your workspaces together in one place. With everything in a single view, you can keep track of all your resources without switching between different tools, ensuring you’re always up to date effortlessly.
