不同用途的Amazon EC2上的 [英] Different between Utilizations for Amazon EC2

问题描述

基于这样的：预留实例可以为1或3年的期限来购买，并且每个实例的一次性费用不予退还。轻型和中型利用预留实例也被实例小时的时间实例处于运行状态结算;如果你没有在一个小时运行的实例，有零使用费。消耗的部分事例小时被标榜为全个小时。重型利用预留实例在整个保留实例期内结算每小时（这意味着你收取的按小时收费，无论是否发生任何使用一个小时内）。

Based upon this: Reserved Instances can be purchased for 1 or 3 year terms, and the one-time fee per instance is non-refundable. Light and Medium Utilization Reserved Instances also are billed by the instance-hour for the time that instances are in a running state; if you do not run the instance in an hour, there is zero usage charge. Partial instance-hours consumed are billed as full hours. Heavy Utilization Reserved Instances are billed for every hour during the entire Reserved Instance term (which means you’re charged the hourly fee regardless of whether any usage has occurred during an hour).

为什么我会永远买重利用包的时候，我可以用轻包装，节省金钱，只要服务器is'nt使用??

Why would I ever buy the heavy utilization package when I could use the light package and save money whenever the server is'nt being used??

推荐答案

抱歉我的previous评论，这的确显得议论，现在我又看了一遍。希望这个答案将弥补这一点。

Apologies for my previous comment, which does seem argumentative now I read it again. Hopefully this answer will make up for it.

通过3种不同的套餐保留的情况下，亚马逊是给你什么，你付出了前面预留实例，多少你每个实例每小时支付运行的实例之间的权衡。在前面的成本是最低的光能利用情况，最低的是重型利用实例，但它周围的其他方式为每小时费用;这是最低的重型利用率最高的光利用率。

With the 3 different packages for reserved instances, Amazon is giving you a tradeoff between what you pay up front for the reserved instance and how much you pay per instance hour for running instances. The up front cost is lowest for Light Utilization instances and lowest for Heavy Utilization instances, but it's the other way around for the hourly cost; that is lowest for Heavy Utilization and highest for Light Utilization.

让我们做一些数学来说明，用一个小型的Linux实例，用一年保留期限。以下是相对价格：

Let's do some math to illustrate, using a Small Linux instance with a one year reservation term. Here are the relative prices:

在锋线上的付款：轻$ 69，$ 195重工

Up front payment: $69 for Light, $195 for Heavy

每小时费用：$ 0.039c轻，$ 0.016c重型

Hourly cost: $0.039c for Light, $0.016c for Heavy

比方说，你在1年保留期运行情况下，每天只需1小时，或365小时。您的总成本将是：

Let's say you run your instances for only 1 hour per day, or 365 hours during the 1 year reservation period. Your total cost would be:

灯：$ 69.00 +（365 * $ 0.039）= $ 83.24

Light: $69.00 + (365 * $0.039) = $83.24

重型：$ 195.00 +（365 * $ 0.016）= $二百点八四

Heavy: $195.00 + (365 * $0.016) = $200.84

但是，当我们运行的情况下，每天20小时7300小时总体而言，我们得到：

But when we run the instances for 20 hours a day or 7300 hours overall, we get:

灯：$ 69.00 +（7300 * $ 0.039）= $三百五十三点七○

Light: $69.00 + (7300 * $0.039) = $353.70

重型：$ 195.00 +（7300 * $ 0.016）= $三百一十一点八〇

Heavy: $195.00 + (7300 * $0.016) = $311.80

所以，如果你仔细predict你的工作量，你可以通过选择合适的定价方案作一些显著的节约。

So if you predict your workload carefully, you can make some significant savings by choosing the right pricing scheme.
