In general, For Microsoft Azure, Amazon, and other vendors, Oracle does not Certify against 3rd party Cloud Products. (this is from Oracle Support but may not be up-to-date info..)
Actually, Oracle and Microsoft Azure have closely integrated, but since it is not OCI , we don't find any good Oracle documentation for this EBS on Azure thing . You have to find blog posts and other web content as well as Azure-side documentation.
This may be a good starting point ->
