Create Azure Single Database
The Single Database deployment option creates a single isolated database in Azure SQL Database
Azure Single Database Support DTU-based and Vcore-based Purchased Model
The internal of SQL Database server is hidden from the end-user and all are managed by Microsoft Azure
Azure Single Database has it is own Resources (DTU or V-Core) and this resource will not be shared with other databases in the same single instance. Each Database has dedicated resources.
Single Database Isolated meaning if you created two single databases on the same single database server each Database has dedicated resources and the two databases cannot be communicated together and I think this one is a security feature
This means Azure Single Database is the best option for small workloads with applications connects to one DB.
To Provision Azure SQL Single Database, you need (resource Group, Database name, Server Name, User Name, Password, Location, deployment option either single or elastic pool, Compute Storage and purchase model either DTU-based or vCore-based)
In Azure SQL Single database provisioning you can create new or select existing one from (Resource group and Server name)
In Azure SQL Single database provisioning the (resource Group, Database name, Server Name) Should be a unique name.
Azure Active Geo-Replication Services is one of the powerful services in Azure used for replicating the SQL database data to another Regions using the same concept of always on data are readable on the another regions and synced on time , With Active Geo-Replication we can configure up to four readable secondary databases in the same or different data center locations (regions).
When we are talking about Performance tuning and Monitoring on Azure SQL Server, we should consider some services provided on azure supporting us in this task
