If you are building database solutions in Azure , using Azure SQL Database then you will know that you have a purchasing option decision to make. That being should you use a vCore model or DTU approach?

Whilst I am not going to write about what these mean or what they are, I want to pass on a point when relating it to costing. My approach is always vCore, not only is it easier for me to understand the compute (rather than a magic number of RAM, IO and CPU – DTUs) but with this model you can apply Azure Hybrid Benefit cost savings on a vCore database and this is not possible for a DTU database. Look at the screen shot below to confirm this. This is taken from the setup page.

DTU –

Something to remember when building databases for your company.
