Question: Is there a “per transaction” cost for Windows Azue SQL Database (SQL Azure)?
Short Answer: No
I recently answered the question on MSDN forum where the question was about Transactions and the associated cost in SQL Azure. As of now, There is no “per transaction” cost associated with SQL Azure. There are two parameters that affect your SQL Azure Bill: 1) Database Size 2) Outbound Data Transfer and an example of an outbound transfer would be data access by an application hosted outside of your Azure DB’s data-center.
