performance-degradation-peak-hours-Issue.yml

#Issue
#Your api-service is experiencing performance degradation during peak traffic times. 
#The service is not scaling properly to handle the increased load, leading to slow response times and timeouts.
#
#Solution
#To resolve this issue, you will configure a Horizontal Pod Autoscaler (HPA) for the api-service to automatically 
#scale the number of pods based on CPU utilization.

#Explanation
#This YAML file contains both the Deployment and the HorizontalPodAutoscaler resources.
#The Deployment manages the api-service, including resource requests and limits.
#The HorizontalPodAutoscaler ensures that the number of replicas is adjusted automatically based on CPU utilization, 
#allowing the service to handle varying loads efficiently.
