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.
