There are several metrics that can be used to measure architectural resilience. These include:
1. Failure rate: This measures how often components or systems fail, giving an insight into their reliability.
2. Mean time to repair: This measures the time taken to repair components or systems after a failure, giving an indication of how quickly the system can recover from disruptions.
3. Mean time between failures: This measures the average time between successive failures, indicating the system's overall resilience to failure.
4. Redundancy: This is the use of multiple components or systems to ensure that if one fails, the others can take over. The degree of redundancy can be measured to determine the system's ability to tolerate failures.
5. Scalability: This measures the system's ability to adapt and continue functioning under changing conditions, such as increased demand or changes in the environment.
6. Security: This measures the system's ability to protect against cyber-attacks, data breaches, and other security threats.
7. Sustainability: This measures the system's ability to maintain its functionality over an extended period while minimizing its impact on the environment.
8. Performance: This measures the system's ability to meet its intended objectives, such as meeting user requirements, providing reliability, and supporting performance.
