Hi @AhmedAl_Attar ,
I do not have experience with this particular one, but I do have experience with similar ones.
In my case, I connected Azure Datalake Gen2 storage (ADLS G2) to SAS Viya using standard file system methods to allow users to store and read/write data, code, outputs, logs etc. This also work with SAS 9.4, no both Linux and Windows.
ADLS, same as S3, are buckets/blobs of data, and the main access is trough APIs. That is the general best practice.
However, there are some methods for users who don't want to bother with API calls, which are all but developers basically. Some create ODBC or driver bridges that transform the File System standard operations into API calls, and provides views.
Nothing of that is officially supported by SAS, since they are not vendor supported, but supported by normally 1 individual developer, or, if you are lucky, a sizable team; therefore it is a call done by each company.
What you need to always do is to read the small letters, to find out the limitations and to find out as well if those limitations are agreeable (user requirements & risk management) by your stakeholders. You might even need to involve Security or the Enterprise Architect in some cases.
In the case of the one you present, I can see the capabilities described here. I see it has some tricky sentences. For example: it mentions that permissions are not supported, deletions, renames... and it speaks of great sequential throughput performance reads, but it mentions nothing about writes, which is something I would like to learn and query more about.

In short, I would like to encourage you to continue this investigation, don't stop only on the marketing statements, test it by yourself, making a risk analysis, and to find out if this one fits your purposes! Noting, of course, that while the SAS Tech Support folks are always willing to help, the responsibility of official support would not fall on their laps and you would need to find proper support for the maintenance of this component.
I hope it helps somehow!
Best regards,
Juan
