How to test if database is hosted on SQL Azure?

Question

Is it possible to test whether a database is hosted on SQL Azure? I am looking at SqlAzureExecutionStrategy for EF6 and only want to apply if the database is actually SQL Azure database.

Currently I am testing if App is running within Azure. However we are looking at allowing clients to host DB themselves so would like some way to identify if DB is a SQL Server or Azure SQL.

Assume EF won't know as it is hiding the implementation details.

Could just have a config setting I guess. Just wondered if it was technically possible.

Updated August 2021 to align with updated documentation

SELECT CASE ServerProperty('EngineEdition')
         WHEN 1 THEN 'Personal'
         WHEN 2 THEN 'Standard'
         WHEN 3 THEN 'Enterprise'
         WHEN 4 THEN 'Express'
         WHEN 5 THEN 'SQL Database'
         WHEN 6 THEN 'Azure Synapse Analytics'
         WHEN 8 THEN 'Azure SQL Managed Instance'
         WHEN 9 THEN 'Azure SQL Edge'
         WHEN 11 THEN 'Azure Synapse serverless SQL pool'
         ELSE 'Unknown'
       END
