ASP .NET Core database on linux?

Question

linux

When working with the technology stack from Microsoft .NET Framework, .NET Core, ASP NET, etc. The most commonly used database is Microsoft SQL Server.
Let's say we have a project on the .NET Framework and ASP NET MVC 5, we deploy it on a machine with Winodws Server. We raise Microsoft SQL Server on this machine and everything works without problems.
And if we have an application on ASP .NET Core and we are going to host it on a machine with linux. How is the base then? You can install SQL Server on linux only from version 2017.
How do you solve this situation?

1. Do they make a separate Window Server for the database?
   
2. Use Postgresql, Oracle?
   

Answer 1

So all options are acceptable, use the one you like:
1. SQL Server 2017/2019 on linux
2. Remotely to Azure SQL Database, or similar
3. Postgresql, Oracle, MySQL, etc.
