We use Azure SQL serverless or with virtual machines.
Azure SQL is used mostly by my clients for ETL.
The most useful feature of Azure SQL is the queries for manipulating the data, such as the tables and the storage processors.
Azure SQL can improve by adding more machine learning features like other databases, such as Cassandra or Cosmos DB.
I have been using SQL Azure for approximately three years.
Azure SQL is a stable solution.
The scalability of Azure SQL is good. However, it is limited by the infrastructure. The cloud version gives more scalability.
The support from Azure SQL is good.
I rate the support from Azure SQL a four out of five.
The initial setup of Azure SQL is of a medium level of difficulty. We need some expertise in installing, configuring, and deploying Azure SQL.
We have approximately 20 to 30 specialists for the deployment of Azure SQL.
The price in general of Azure SQL could improve.
We have enterprises in Chile, Peru, Spain, Italy, and Colombia that provide IT services. We use this solution every day to maintain new projects and use the on-premise and cloud versions.

I rate Azure SQL a nine out of ten.
