The cloud-native architecture centered around microservices proves to be a strong system that ensures what key quality in software systems?

• A. Throughput
• B. Latency
• C. Maintainability
• D. Resiliency

Answer: (D)

The main idea is resilience. In a cloud-native, microservices-based setup, the system is designed so failures in one service don’t bring everything down. Each service runs independently, scales on its own, and is guarded with mechanisms like timeouts, retries, circuit breakers, and bulkheads. If a service hiccups or fails, others continue operating, and traffic can be rerouted or degraded gracefully rather than causing a total outage. This isolation and automated fault tolerance build a system that remains available and functional even under partial failures, which is the core strength of cloud-native microservices. While maintainability, throughput, or latency are relevant considerations, resilience is the quality most strengthened by this architectural approach.
