Data Platform Tips 19 - What are DTUs on Azure SQL Database?

DTU (Database Transaction Unit) is a blended measure of CPU, memory, reads and writes. It provides a pre-configured capacity for a specific price for every month.

DTU model is available for Azure SQL Databases and not for managed instances.

It is always better to start with low DTUs if you are not sure about the capacity as Azure allows you to increase the DTUs based on your loads.

To migrate on-premises sql server to Azure and to calculate the required DTUs, use the DTU Calculator.
