 an automated solution designed to meet all Kubernetes resource optimization needs.
 
 This approach shifts the optimization responsibility from service owners to the platform team (Tortoises),

 On the other hand, service owners are required to configure only a minimal number of parameters 
 to initiate autoscaling with Tortoise, significantly simplifying their involvement.
