我在Kubernetes中有一个部署，它利用了HorizontalPodAutoscaler。CPU和内存的averageUtilization的建议或典型设置是什么？我在每个pod中运行了一个FastAPI和React镜像，想知道你们在生产环境中对averageUtilization设置有什么经验。

apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
metadata:
  name: ***
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: ***
  minReplicas: 2
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 70
  - type: Resource
    resource:
      name: memory
      target:
        type: Utilization
        averageUtilization: 70

我当前的CPU和内存阈值设置为70%。
