Which architectural principle refers to separating dependent components so a failure in one does not directly break others in the AWS Cloud?

Loosely coupling components is an architectural principle that promotes designing systems where individual components are independent and interact through well-defined interfaces. This separation ensures that a failure in one component does not cascade and cause widespread outages in other dependent components, enhancing fault tolerance and resilience. For example, using message queues to decouple microservices allows them to operate independently. Using a monolithic design is the opposite, where all components are tightly integrated, making the system vulnerable to single points of failure. Designing for automation is a good principle but doesn't directly address component failure isolation. Designing for single points of failure is an anti-pattern and would lead to an unreliable system.
