推荐答案

预留实例是计费功能，而不是技术功能.

Reserved instances are a billing feature, not a technical feature.

您可以购买预留实例，折扣的小时费率将适用于已运行的实例，无需对其进行任何操作.只需确保您购买的预留实例是:- 在与您已经运行的实例相同的可用区中- 与您已经运行的实例具有相同的实例类型(m1.small、c1.medium 等).

You can purchase a reserved instance and the discounted hourly rate will apply to already-running instances, without needing to do anything to them. Just make sure the reserved instances you purchase are: - in the same availability zone as your already-running instances - of the same instance type (m1.small, c1.medium, etc) as your already-running instances.

一旦预订费用清除了您的信用卡，您就会看到折扣的小时费率对您已经在运行的实例生效.

As soon as the reservation cost clears your credit card you will see the discounted hourly rate take effect for your already-running instances.

亚马逊的文档在这方面可能更清楚.http://aws.amazon.com/ec2/reserved-instances/#4

Amazon's docs could be a lot clearer on this. http://aws.amazon.com/ec2/reserved-instances/#4
