    Deploy like any asp.net core site. Your cloud host must support .net core apps, and should have docs for deployment. A windows host my support WebDeploy, or you may need to ftp.

    Is there an easy way to create database and tables on the test server on cloud? On my local machine it is SQL express.

    Looks deployed correctly. Just a startup error connecting to the database. You hosting provider should support different database engines. Pick and configure one, then be sure you pick one that EF support and build with the correct driver. Typically ally when you configure you database in the cloud, the configuration includes the connection string.

    It is Windows Server 2012 and SQL Server 2017 on top of it. Is there a practical way to create tables on it via EF Core? Or should I create them manually by creating scripts? Is there a step-by-step guide to creating tables and applying migrations to the remote database?

    It is not Azure, a virtual server on the hosting cloud.
