Reducing Inter-dependencies in AWS Cloud Application Design

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.

The non-functional requirement of reducing inter-dependencies so failures do not impact other components relates to the concept of decoupling.

Decoupling refers to the practice of designing an application or system in a way that minimizes dependencies between its components. This approach makes the system more flexible and resilient because it reduces the impact of failures in one component on other components.

In the context of AWS Cloud, decoupling is typically achieved by using loosely coupled services that communicate through well-defined APIs. For example, AWS Lambda, Amazon Simple Notification Service (SNS), and Amazon Simple Queue Service (SQS) are commonly used services that help to decouple components in an AWS-based application.

By using these services, developers can create a more modular architecture that isolates failures and improves the overall reliability of the application. Additionally, decoupling can also improve scalability, as it allows developers to scale individual components independently without affecting the rest of the system.

In summary, decoupling is an important concept in designing applications for the AWS Cloud because it helps to reduce inter-dependencies and improves the reliability and scalability of the system.
