Non-Resilient Systems
Non-resilient systems are software or hardware systems that lack mechanisms to handle failures, errors, or unexpected conditions gracefully, leading to crashes, data loss, or service interruptions when issues arise. They are characterized by a brittle architecture that assumes ideal operating conditions and cannot recover from faults without manual intervention. This concept is often discussed in contrast to resilient or fault-tolerant systems, which are designed to maintain functionality despite disruptions.
Developers should understand non-resilient systems to recognize anti-patterns and design flaws that can compromise reliability, especially in critical applications like financial services or healthcare where downtime is costly. Learning about this concept helps in identifying when to implement resilience strategies, such as redundancy, error handling, or monitoring, to prevent system failures. It is particularly relevant when maintaining legacy systems or during code reviews to flag vulnerabilities that could lead to outages.
