What are the main challenges of designing fault-tolerant systems?

Designing fault-tolerant systems involves several challenges, including ensuring redundancy, managing complexity, and maintaining performance under failure conditions.

Can you explain what redundancy means in this context?

Redundancy in fault-tolerant systems refers to the inclusion of extra components or systems that can take over in case of a failure, ensuring continuous operation.

How does complexity affect fault tolerance?

Increased complexity can lead to more potential points of failure, making it harder to predict and manage system behavior during faults.

What strategies can be used to improve fault tolerance?

Strategies include implementing error detection and correction, using diverse redundancy, and conducting regular system testing to identify weaknesses.

Are there any real-world examples of fault-tolerant systems?

Yes, examples include aerospace systems, financial transaction systems, and cloud computing architectures that ensure high availability.
