Secure your Database Connection

In the guide Provision and Binding Cloud Resources and Provision a Database and Import a SQL File for initialization, a database's public host DB_PUBLIC_HOS is used to connect by business component. It's necessary when you want to have a try, create a PoC, or use the database outside a cloud provider. But it's not secure for production use of database.

This tutorial will talk about how to secure your database connection.
