What is the OS used by Azure SQL

Question

We are in the process of certifying our product with Azure SQL as back end. Considering our entire product being hosted on AKS , Linux based VM , would like to know the OS type of Azure SQL.

Answer 1

Good day,

You speak about Azure SQL and use the tag azure-sql-database. Therefore, I assume that you means Azure SQL Database, which is a database service. it is not relevant how Microsoft provides you the service. Microsoft can use any solution which they find best for them in order to host the service, including using any operating system which they want. Moreover, even if we/they will provide the current architecture behind the scenes then no one guarantee that it will stay the same tomorrow and no one will inform you if it is changed in public channels probably.

You need to choose if you want to use database level service (Azure SQL Database) or server level service (Azure SQL Managed Instance) or hosting level service (Azure Virtual machine - in this case you can control the OS)

Answer 2

When you create Azure SQL DB, you don't have to worry about the OS. It is managed by Azure. We just create Azure SQL DB and get started. If you want the control over OS, you will have to go with option - SQL Server on VM.

Reference: Choose azure databases

@Honey Nadackal
As pointed out in the other answers by @Ronen Ariely and @Vaibhav Chaudhari , Azure PaaS services are offerings backed by performance and availability SLA's. These apply irrespective of the underlying OS/architecture.
As and end customer consuming these services, you shouldn't be concerned about the underlying implementation as such.

You had asked a similar question regarding Azure database for PostgreSQL as well.
Just out of curiosity, is there a reason you need to know about the host operating system?
