Which AWS architectural best practice will meet this requirement?
Use request throttling
Use a stateful service
Implement automatic data backups
Implement loose coupling
Explanations:
Request throttling helps manage the rate of requests to a service but does not inherently prevent one component from negatively impacting another. It can limit overload but doesn’t ensure isolation between components.
A stateful service retains information about the state across requests, which can lead to tighter coupling between components. This can make the system more vulnerable to one component affecting another negatively, especially if the state is shared.
Implementing automatic data backups is crucial for data recovery and resilience but does not address the interaction between components. It does not prevent one component’s failure or performance issues from affecting others.
Implementing loose coupling ensures that components interact with each other through well-defined interfaces, minimizing dependencies. This architectural style allows components to operate independently, so issues in one component are less likely to impact others, enhancing overall system resilience.
