Which design principle should the company use to meet this requirement?
To ensure that an application remains available even if an individual component fails, the design principle of loose coupling should be applied. Loose coupling means that the components of the application are independent of one another, so a failure in one does not affect the others. This design principle allows the system to isolate and manage failures without causing widespread outages, thereby maintaining the application's availability.
Loose coupling reduces the risk that a change made in one component, such as a database or user interface, creates unanticipated changes in other parts.
