Each serverless function execution is isolated from others. A failure doesn’t crash the entire system. Automatic retries and redundancy handle transient issues. There’s no single point of failure. This design increases overall system resilience.
System reliability improves even under unstable conditions. Outages are contained.
This resilience is crucial for mission-critical applications.
Serverless isolates failures at the function level.
