Question

Accepted Answer

To scale up application, use load balancers and monitor logs to identify failures.

Monitor logs to identify where the failure occurred
Implement fault tolerance and redundancy to prevent future failures
Use auto-scaling to automatically add or remove instances based on traffic
Real-world example: Amazon Web Services (AWS) uses load balancers and auto-scaling to handle millions of requests
Code example: Use try-catch blocks and logging to identify and handle exceptions
