Question - What do you understand by to be Resilient for a Reactive System?
Answer -
To be Resilient for a Reactive System means the system will stay responsive if it gets any chance of failure. Any system that is not resilient will be unresponsive after a failure. Resilience is achieved by replication, containment, isolation and delegation. Failures are contained within each component, isolating components from each other, thereby ensuring that parts of the system can fail and recover without compromising the entire system.
