The cloud native architecture centered around microservices provides a strong system that ensures ______________.

Fallback is a specific pattern within resiliency, but resiliency encompasses the broader ability of a system to recover and continue functioning.

Microservices promote independent deployment and scaling, allowing individual components to fail without bringing down the entire system, and enabling quick recovery, thus enhancing overall system resiliency. This architecture, coupled with patterns like circuit breakers and retry mechanisms, ensures the application can continue functioning despite transient issues.

Failover is a mechanism for switching to a redundant system upon failure, which contributes to resiliency but is not the sole overarching benefit.

High reachability refers to accessibility, which is a desirable outcome but not the core architectural principle ensured by microservices in the same way resiliency is.
