Sarah: "Hi David, now we'll talk about transport and landscapes! Have you heard about the "3-System Landscape"?"
Sarah: "Your SAP S/4HANA Cloud, public edition system is generally offered as a 3-System Landscape. This means that all custom configuration takes place locally within a Development Tenant.
All custom configuration is then transported to the Test Tenant and subsequently to the Production Tenant.
I've suggested to David the following link to get more information about this topic."
