Hi,
Azure portal and DMV providing % of memory used by database
I want to query MAX RAM in GB allocated to server assuming we have only one customer database per server
DTU 500 = ? GB Ram , DTU 1750 = ? GB Ram
Is this information secret ? 🙂

Thank you
Alex

From what I understand, DTU is not based on RAM alone. Please see the following article.

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
