I have a STAGING and PROD environment, web apps, SQL databases, etc in Azure. Currently, the scale of the SQL db for PROD is much higher than STAGING - no surprises there.
I suppose there is some temptation to save money by pooling these SQL resources together with an SQL Elastic Pool. However I'm concerned that it will create a coupling between STAGING and PROD which everything inside me screams is a bad idea.
What are the legitimate drawbacks that could reasonably affect performance, reliability, security, etc?
