We are currently using on-premises SSAS-Tabular cubes feeding from the Snowflake Cloud database.
We achieve this using ODBC Drivers to Snowflake.
So far so good but it requires setting up an ODBC datasource on the SQL Server machine itself.
We would like to test/use Azure Analysis Services instead.
We deployed our cube to Azure but cannot process it because we do not have our ODBC drivers setup in Azure.
Is there a way to access Snowflake Cloud database from within Azure Analysis Services?
Thanks

I am migrating from an older version of Microsoft SQL to Azure SQL. The existing SQL Server stored procedures use OPENQUERY and a linked ADSI server to retrieve user information directly from the Active Directory.
Is this possible in Azure SQL?
Azure SQL Database only allows to query another Azure SQL Database (remote) or Azure Synapse Analytics databases using elastic queries. All other SQL and non-SQL sources are not allowed.
Azure Managed Instance uses a private VNET and supports linked servers to a limited number of targets. Supported targets: SQL Server and SQL Database. Not supported targets: Active Directory, files, Excel, Oracle, MySQL, Analysis Services, and other RDBMS.
Azure SQL Database would have no way to communicate with your on-premises servers since it does not uses private VNETs as Managed Instance does.
If you rely heavily on this you should discard all Azure SQL (PaaS) options and go for a SQL Server Azure VM.
I'm trying to query an on-premises SQL Server database from an Azure SQL database. I understand that the elastic query feature allows you to query across multiple databases in Azure SQL Database. But, it doesn't work with querying an on-premises database. Is there any way to do this?
Elastic database queries work between Azure SQL Databases and to query Azure SQL Data Warehouse only. From an architecture point of view on the scenario you describe, Azure would be relying on a server outside of its infrastructure to satisfy a query, if elastic queries were allowing creating external data sources to on-premises SQL Server instances. A better architecture may be replicating the on-premises database to a hub database on Azure SQL using SQL Data Sync and then create elastic queries using that hub database. Even from a performance point of view makes more sense, since queries won't be executing against your on-premises databases and latency will be less a factor.
Another option you have is to consider using Azure Managed Instance with allows you to create Linked Servers that can connect to on-premises databases as you can read here. Azure Managed Instance supports running on a private VNet, from which it's reasonable to connect to on-premises SQL Server instances. Azure SQL Database would have no way to communicate with your on-premises servers.
I am planning to use scribe insight for integration. I have used SQL server with scribe before. But they were related to the same Active directory. But this time my source will be a SQL server hosted in the cloud.
Is it really possible to use a cloud based SQL server as a source?
What kind of adapter should I use?
I have a business scenario where web site and SQL database will be on cloud and after some operations want to save the cloud SQL data to the SQL database which is on-premises and not exposed to the internet.
What would be the best architecture for this scenario?
Need suggestions.
you can either setup a VNET to connect your Website to your on-premises SQL Server or you can configure Azure Hybrid Connect. (see this link)
If the website does not use local resources you can always go for azure websites. Choose the tier based on the requirement.
As far as the database is concerned you choose azure sql database. ( tier based on requirement-size and performance) . You can set up azure sql sync (in preview) to sync between sql azure and local sql server. Or you can take a back up of sql azure db - bacpac. and then restore it local sql server using sql management studio.
I am currently learning Azure. In terms of data store, I see Azure SQL and the migration tool. If you have SQL server 2008 or Oracle, would you be required to migrate in order to use Azure?
I know you can access/query the Azure datastore via web browser or azure tools. Is there anything equivalent to working locally (or setting up local azure sql db)?
Azure is a platform with various components. you can opt to migrate your database to Azure SQL Database, run a Azure VM with either Oracle or SQL Server, or retain your current databases on-premise and make use of VPNs to connect your on-premise databases and your Azure-based application.
There is no emulator for Azure SQL Database. for local development, you can point it to as SQL Express, LocalDB or SQL Server.
