Which layer should each tenant have dedicated to their specific tenancy in a multitenant implementation?

In a multitenant implementation, it is essential for each tenant to have its own dedicated layer that handles tenant-specific functionality and configurations. This allows for customization and distinct management for each tenant while ensuring that the underlying system remains stable and shareable among different tenants.

The Project layer is designed for this purpose. It contains tenant-specific items, such as templates, content, and any customizations needed that pertain to the unique business logic or requirements of that specific tenant. Isolating these customizations in the Project layer enables developers to maintain clear separation between different tenants' data and functionality, minimizing potential conflicts and ensuring that each tenant can operate independently while leveraging the shared resources of the platform.

In contrast, the Foundation layer typically handles cross-tenant shared utilities, while the Feature layer often encompasses functionalities that can be used across multiple tenants but do not need specific customizations. Therefore, the Project layer is the most appropriate choice to ensure each tenant's specific needs are met within a multitenant framework.
