My main use case for Fabric Data is to get the data from multiple data sources, whether on-premises or other cloud service providers, and store that data into Lakehouse or warehouse, prepare a data model for them, and create reports with the Power BI Desktop.
A specific example of how I have used Fabric Data recently includes a project where data was coming from Oracle and IBM, and there was another data source. All of it was getting combined in Snowflake, and I performed Snowflake mirroring with Fabric Data where all the data is mirrored into the Fabric environment, and then I had to create the data models for the Power BI reports.
Fabric Data enables me to get the data from multiple resources, whether on-premises or any other Azure service providers, and also allows me to transfer and migrate the data from any other platform to Fabric Data smoothly. I accomplish this in the form of files or text, using the functional features of Delta Lake in the Parquet format for transactional data and historical data, and I can store the data in the form of tables or create a data warehouse for data modeling and more.
One use case I can share is that if we have a tenant in which we have multiple users, each user gets a Fabric Data free trial of sixty days in which he or she can explore Fabric Data items depending upon the client's requirement. This gives us the opportunity to only pay for one particular tenant level Fabric Data capacity while all the other users can use the same.
