[英]AWS Reserve Instance Billing
I have about 8 EC2 Windows t2.small instances iam paying about $0.03 (on-demand) Total is about 5840 hrs/month. 我有大约8个EC2 Windows t2.small实例,我支付约0.03美元(按需)总计约5840小时/月。 If I buy 1 reserve instance for 1 year is a total of about 8760 hrs
如果我购买1个储备实例1年,总共约8760小时
Will the bill for this reserve instance be applied to all my 8 EC2 pricing ? 这个储备实例的账单是否适用于我所有的8 EC2定价? Or will it be only applied to 1 of them ?
或者它只适用于其中一个?
I ask these because I am not sure I will have all 8 instances for 1 year, but I am sure I will have them for at least 3 months. 我问这些是因为我不确定我将在1年内完成所有8个实例,但我相信我会拥有它们至少3个月。 So I can pay upfront for 17520 hrs of EC2 t2.small Windows.
所以我可以预先支付17520小时的EC2 t2.small Windows。
All my EC2 run 24/7 我所有的EC2全天候运行
As long as you run at least one t2.small
instance running all the time, your reserved instance rate will be applied to that instance. 只要您运行至少一个
t2.small
实例一直运行,您的预留实例速率将应用于该实例。
If you have 8 instances running, 7 will be charged on-demand price one will be charged for reserved instance price. 如果您有8个实例正在运行,则7个将按需收取费用,将按预留实例价格收取费用。
If you have 2 instances running, you will be charged one for on-demand and one for reserved instance. 如果您有2个实例正在运行,那么您将按需按需付费一个,为保留实例付费一个。
If you have no instance running, you will be charged for one reserved instance. 如果您没有运行实例,则需要为一个预留实例付费。
If you will be running the instance for three months only, do not buy reserved instance since it is not cost effective. 如果您将仅运行实例三个月,请不要购买预留实例,因为它不符合成本效益。 Instead try the Reserved Instance Marketplace , where some people sell their unused reserved instances.
而是尝试预留实例市场 ,其中一些人出售他们未使用的预留实例。
If you buy 1 reserve instance for 1 year then you'll be charge separately for that 1 reserved instance.It is calculated on the basis of reserved instance rate. 如果您购买1个预留实例1年,那么您将分别为该1个预留实例收费。它是根据预留实例率计算的。
Rest all will be charged on the "on-demand" basis rate. 休息所有将按“按需”基准费率收费。
The simplest way to think of a Reserved Instance is that you are pre-purchasing (annually or monthly) the right to run one matching instance every hour of the year at now hourly cost. 考虑预留实例的最简单方法是,您预先购买(每年或每月)以一小时成本每年每小时运行一个匹配实例的权利。
