several different recommendation types, each with values for CPU and memory:
Lower Bound: this is the lower bound number VPA looks at for triggering a resize. If your pod utilization goes below this, VPA will delete the pod and scale it down.
Target: this is the value VPA will use when resizing the pod.
Uncapped Target: if no minimum or maximum capacity is assigned to the VPA, this will be the target utilization for VPA.
Upper Bound: this is the upper bound number VPA looks at for triggering a resize. If your pod utilization goes above this, VPA will delete the pod and scale it up.
