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?

A. B. C. D.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.

Decoupling is a design approach that emphasizes reducing dependencies between components of a system. By minimizing the dependencies, each component can function independently, reducing the risk of failures spreading across the system.
In the context of AWS Cloud, decoupling can be achieved through the use of various services such as Amazon S3, Amazon SQS, and AWS Lambda. These services allow different components of an application to interact with each other through well-defined APIs, without having to be tightly coupled.
For example, instead of having components directly communicate with each other, they can communicate via Amazon S3 or Amazon SQS, which act as a buffer between them. Similarly, instead of having a monolithic application, AWS Lambda can be used to break down the application into smaller, independent functions that can be executed separately.
By decoupling components, the application becomes more resilient to failures since any failures that occur in one component are less likely to affect other components. This approach also makes it easier to scale individual components independently, as well as to replace or upgrade them without affecting the rest of the application.
Therefore, in the context of the given non-functional requirement, the design team should focus on decoupling components to reduce inter-dependencies and minimize the impact of failures on other components.
