Azure SQL vs On Premise SQL Server

(0) ShareShare
ReportReport
Posted on by pyee 35

I haven't found any articles outlining the primary differences (if any) between Azure SQL database and an on-Premise database via Data Gateway for running PowerApps applications.

 

  • Is delegation exactly the same?
  • Has anyone noticed any performance gains/hits? I realize this may depend on the specs on each database, but I'm assuming any comparisons are pretty similar spec.
  • Are they developing new features on one of these faster than the other?
  • Anything I don't know I should be asking?

I'm using on-premise databases now, but thinking about migrating the PowerApps back-ends to Azure. Any gotchas I should be aware of first?


Thanks!

    Hi @pyee,

    For your first question, the On-premise SQL Server and Azure SQL Server have same Delegation functionality. More details about the Delegable data sources, please check the following article:

    https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/delegation-list

     

    For your second question, I think an app connects to a Azure SQL Server has a better performance than an app to On-premise SQL Server.

     

    For your third question, there are also some known limits in SQL Server connector, please check the following article for more details:

    https://docs.microsoft.com/en-us/connectors/sql/#known-issues-and-limitations

     

    Best regards,

    Kris
