Q. Why was TCS erroring and not returning data
A. TCS was unable to process the requests in a timely manner due to high CPU utilization and memory.
Q. Why were there not enough tasks to handle the increased load?
A. Auto-scaling was not enabled, so the system did not automatically scale up the number of tasks in response to the surge in traffic.

Lessons Learned
Importance of Auto-Scaling: The absence of auto-scaling left the system vulnerable to unexpected traffic surges, highlighting the critical need for automated scaling mechanisms to handle dynamic workloads efficiently.
Proactive Resource Management: Relying solely on static resource allocation can lead to bottlenecks during periods of high demand. Regular reviews of scaling configurations and resource management policies are essential to ensure the infrastructure can adapt to changing load patterns.
Monitoring and Early Detection: Enhanced monitoring and alerting are crucial for identifying system strain early. By detecting potential issues before they affect service performance, proactive interventions can be made to avoid disruptions.
