What is DTU? DTU = Database Throughput Units Resources assigned to a database Unified measure of CPU+Memory+Read/write rates CPU Writes Reads Memory 40% 65% 30% 50% Utilization https://msdn.microsoft.com/en-us/library/ms189457.aspx

What is DTU – DTU Calculator How to calculate the needed DTU to my SQL Database? You can predict the service tier  Too much: Not cost effective. Too less: You can put your database in trouble (and you!). DTU Calculator Online service (http://dtucalculator.azurewebsites.net/) Based on collected performance indicators. Processor - % Processor Time Logical Disk - Disk Reads/sec Logical Disk - Disk Writes/sec Database - Log Bytes Flushed/sec Does not take into account: Uptime SLA Point in time Restore Performance Objective https://msdn.microsoft.com/en-us/library/ms189457.aspx
