![]() In my thought, If the deployed database will not consume too many resources the DTU-Based purchase model will be more suitable. Virtual Core (vCore)-Based purchasing modelĪ purchasing model decision directly affects the database performance and the total amount of the bills. Undoubtedly, nobody wants to pay money for the redundant resources or features that they do not use or plan to use.Īt this point, Microsoft Azure offers two different purchasing models to provide cost-efficiency:ĭatabase Transaction Unit (DTU)-Based purchasing model. The significant consideration of the Azure SQL Database is to meet the performance requirement of the deployed database against the minimum cost. If you still keep the database backup file, i think you can try this calculator. Here is a link about Azure SQL Database DTU Calculator.This calculator will help us determine the number of DTUs for our existing SQL Server database(s) as well as a recommendation of the minimum performance level and service tier that we need before we migrate to Azure SQL Database. Please see: Monitoring and performance tuning: ![]() Since your DB instances are already on Azure, you can monitor your DB instances and improve your DB Performance with Azure Portal by troubleshot or change the service tiers. The DTU-based purchasing model offers a set of preconfigured bundles of compute resources and included storage to drive different levels of application performance: Basic, Standard and Premium. The Database Transaction Unit (DTU) represents a blended measure of CPU, memory, reads, and writes. Compute sizes are expressed in terms of Database.Transaction Units (DTUs) for single databases and elastic Database Transaction Units (eDTUs) for elastic pools. Azure SQL Database provides two purchasing models: vCore-based purchasing model and DTU-based purchasing model.ĭTU-based purchasing model is based on a bundled measure of compute, storage, and IO resources.
