Resilient System Meaning

A resilient system is one that possesses the capability to effectively adapt, recover, and maintain operational functionality in the face of disruptions, challenges, or unexpected events. It encompasses the ability to withstand and recover from various forms of adversity, including failures, faults, errors, or external threats, while minimizing the impact on overall performance and service availability. The primary goal of resilient systems is to maintain operational integrity, reliability, and service delivery even in the presence of adverse conditions or unforeseen circumstances.

Some of the important points regarding the Resilient System:

• Fault Tolerance: Resilient systems can tolerate faults and failures without experiencing complete system failure, often through redundancy and failover mechanisms.
• Redundancy: Resilient systems incorporate redundancy at various levels to provide backup and ensure critical functions can be performed even if primary components fail.
• Failover and Recovery: Resilient systems automatically switch to backup resources or alternate paths to maintain service availability in the event of a failure, with procedures in place to restore the system to a stable state.
• Isolation and Containment: Resilient systems isolate failures to prevent them from propagating and affecting other parts of the system, using techniques like compartmentalization and encapsulation.
• Monitoring and Alerting: Resilient systems continuously monitor their health and state, detecting anomalies and failures and alerting operators for proactive mitigation.
