Power BI dataflow Gen1 needs Gateway to connect to Azure SQL DB
I’m in the progress of migrating some legacy stuff at a client, and in their Power BI environment there are still quite some Power BI dataflows Gen1. I had migrated an Azure Synapse Dedicated SQL Pool to an Azure SQL DB (much cheaper for their volume of data), and in the dev/test environment all dataflows […]

Book Review – Microsoft Power BI Performance Best Practices
I was asked to do a review of the book Microsoft Power BI Performance Best Practices 2nd edition (Amazon link), which means I got a copy for free. The book is written by Thomas Leblanc and Bhavik Merchant and published by Packt. As the title obviously implicates, the book aims to give you a set […]

When you have a organization with multiple tenants in Azure (also called directories in some products like Azure Devops), or you’re a consultant like me who works with multiple clients […]

Sometimes your Microsoft Entra ID account (formerly known as Azure Active Directory) is added as a guest user in another tenant. This happens quite a lot when you’re a consultant and your client can’t create a new user in their own tenant, so they add the account of your own company as a guest instead. […]

Both connect to the same Azure SQL database, but with different SQL users (they have both different permissions on the data in the database). This can be a use case for example where you have data for multiple clients inside one single […]
