Hello @manish verma - sorry for the delayed response.
If I understand your question correctly, you are looking for documentation on Azure-based Data Fabric solutions.
I recommend starting with this content on using complimentary Azure-based Data solutions to design a virtualized Data Warehouse - refer to illustration below.
Also worth pointing out that third party solutions like Denodo and Netapp both have integrated solutions with Azure platform - check out the hyperlinks for details. Also sharing this Product-comparison content that may be useful for you to make an informed decision on what product to chose for your business & customer scenarios.
Hope this helps but dont hesitate to ping if you have any followup questions.
Regards.
