Hi @ArunRaaman ,
Welcome to Microsoft Q&A!
Base on my research, this is a Azure issue, not SSAS issue. You could refer to this thread, see below:
Database Server runs your databases. You can't create "Single Database" without a server.
You pay only for databases/elastic pools, but you manage them through database server.
One server can host many databases.
Database Server is free and is mostly a logical/management tool, something like a "Resource Group".
And also you could get more details from below reference:
What is a single database in Azure SQL Database?
Best regards,
Carrin
