A company is building a new application on AWS. The company needs the application to remain available if an individual application component fails.

Which design principle should the company use to meet this requirement?

Show Suggested Answer Hide Answer
Suggested Answer: D

Loose coupling is a design principle that involves reducing dependencies between application components so that they can operate independently. This approach ensures that the failure of one component does not affect the availability of the others, thereby improving the application's fault tolerance and resilience. Disposable resources, automation, and rightsizing are valuable principles in cloud architecture, but they do not directly address the requirement of remaining available despite the failure of an individual component like loose coupling does.

Disposable resources can be useful too, but not the main focus here.

Automation seems important too, but I’m not convinced it directly addresses the availability requirement like loose coupling does.

I feel like we had a practice question on this, and I think loose coupling was the answer because it allows for better fault tolerance.

I’m not entirely sure, but I think disposable resources might be more about scaling rather than availability.

I remember we discussed loose coupling in class as a way to ensure that components can fail independently without affecting the whole system.

Loose coupling seems like the right approach here. If the application components are loosely coupled, then a failure in one component won't bring down the entire application. Gotta love that fault tolerance!

Hmm, I'm not totally sure about this one. I'm debating between Loose coupling and Disposable resources. I'll have to think it through a bit more.

This looks like a classic question on AWS design principles. I think the answer is Loose coupling, since the question specifically mentions the need for the application to remain available if an individual component fails.

Automation could also be a good option, since you'd want the system to be able to automatically recover from component failures. But I think Loose coupling is the more direct answer to the question.
