Universal Containers (UC) innovative apps division is releasing an application that can be installed in its trading partners Salesforce environments. The application lets the trading partners book containers from UC directly without leaving their own Salesforce environment.
The partners can then build on top of the application with process builders and triggers so the container booking process can be integrated with the trading partners' own processes.
What is the recommended mechanism for releasing the application considering the innovative apps division wants to keep the application up to date in various environments?
