In an example,
I have Resource Group A that has Azure SQL 1 and Web App 1.
I have Resource Group B that has Azure SQL 2 and Web App 2.
Can Azure SQL 1 see/do queries in Azure SQL 2?
Can Web App 1 call database Azure SQL 2?
In another words, is Resource Group a way to organize the work, but does not put up walls from one to another?
I was planning on creating a Resource Group DEV, QA and UAT. But a database is required to be used in all 3 environments.
My thoughts it having this database in another resource group and DEV/QA/UAT web apps access it when it needs.
