Architecture evolution can have a significant impact on the reliability of a system. As a system evolves, it may become more complex, with additional components, interfaces, and dependencies. These changes can increase the likelihood of failures and make it more difficult to diagnose and recover from them.
On the other hand, if architectural evolution is carried out correctly, it can lead to improved reliability. For example, if new components are added to the system, they can be designed with greater robustness and fault tolerance than the existing components. Similarly, if the architecture is restructured to reduce dependencies and simplify interfaces, this can make it easier to isolate and fix faults.
Overall, the impact of architecture evolution on reliability depends on how it is managed. Careful planning, testing, and monitoring can help ensure that changes to the architecture improve rather than degrade reliability.
