Your design team is planning to design an application that will be hosted on the AWS Cloud. One of their main non-functional requirements is given below:
Reduce inter-dependencies so failures do not impact other components.
Which of the following concepts does this requirement relate to?
 

Answer options:

A.Integration
B.Decoupling
C.Aggregation
D.Segregation

Answer – B
The entire concept of decoupling components ensures that the different components of applications can be managed and maintained separately. If all components are tightly coupled, the entire application would go down when one component goes down. Hence it is always a better practice to decouple application components.
