The reason is that it is an initiator for many other services, and if it scales up to fast it starts suffocating and crashing the system, I want it to scale, let the other deployments scale in response, and then scale ...

There are three types of K8s autoscalers, each serving a different purpose. They are: Horizontal Pod Autoscaler (HPA): adjusts the number of replicas of an application.HPA scales the number of pods in a replication controller, deployment, replica set, or stateful set based on CPU utilization.A Doppler ultrasound is an imaging test that uses sound waves to show blood moving through blood vessels.
