在特定时间配置自动缩放

我想创建一个Opsworks stack，其中包含Autoscaling Group，以便可以根据费用动态添加实例。现在，为了我的环境，00h，6h，12h和18h总是有很高的利用率。我正在寻找一种在这些时间配置自动调节的方法：在以前的每个小时，通过Autoscaling Group添加4个实例，其余时间只有一个实例在线。在特定时间配置自动缩放

我也跟着这Document，以便该实例从该层注销Lambda Function。

下面是摘录：

     } 
     } 
    },

      "Value": "opsworks_stack_id", 
      "PropagateAtLaunch": true 
     }], 
     } 
    },

我如何配置此类型的自动缩放的？我应该使用Time-based吗？任何建议，非常感谢。

你有没有考虑过使用用opsworks自动缩放？ http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-autoscaling-loadbased.html http://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-autoscaling.html #cwalarms – strongjz

是的，但还不够。我想我会同时使用;传统的自动缩放和基于时间的实例 – Somar

您可以在一个时间段使用的AWS::AutoScaling::ScheduledAction资源自动缩放，您AutoScalingGroup的高利用率的周期后（和缩小例如，30分钟后）：

ScaleUp: 
    Type: AWS::AutoScaling::ScheduledAction 
    Properties: 
    AutoScalingGroupName: !Ref AutoScalingGroup 
    MinSize: 5 
    Recurrence: 0 23,5,11,17 * * * 
ScaleDown: 
    Type: AWS::AutoScaling::ScheduledAction 
    Properties: 
    AutoScalingGroupName: !Ref AutoScalingGroup 
    MinSize: 1 
    Recurrence: 30 0,6,12,18 * * *
