In Azure, you can use any of the three SQL databases options listed in this link to host your Becktechnology databases - Azure SQL Documentation.
Additional Pricing Info can be found at the link below
Here are links to set up each option through the portal:

How to set up a Windows SQL VM in Azure
Once you have your instance set up and configured the next step is to push or import the databases to your Azure SQL instance using SSMS.
The example below is pushing the database from your SQL Server into the Azure SQL (.bak files)
The example below is importing backpac files directly into Azure (.bacpac files)
The next step is to add the user's IP address in the firewall tab - setting up IP access to the firewall.
Also, you can use Azure Active Directory to connect the users to the database - How to set up and configure Azure Active directory.
To manage database permission please see this article - Azure SQL database access.
We use this command to create SQL database access for the users:
replace becktech with your SQL user name
replace password with your SQL password
CREATE USER becktech WITH PASSWORD = 'password here';
EXEC sp_addrolemember 'db_owner', 'becktech';
The next step is to create the profiles for the databases. If you are using the serverless option then you will need to use this article to create azure database profiles.
