Amazon RDS 如何计算 I/O 率? [英] How does Amazon RDS calculate I/O rate?

问题描述

我今天浏览了 Amazon RDS 定价网站，现在想知道他们实际上是如何计算 I/O 率的?每 100 万个请求 0.10 美元"的真正含义是什么?

I browsed the Amazon RDS pricing site today and now do want to know how they actually calculate the I/O rate? What does "$0.10 per 1 million requests" really mean?

谁能举一些简单的例子，从 EC2 到 RDS 上的 MySQL 的简单查询会产生多少 I/O?

Can anyone give some simple examples how many I/Os a simple query from EC2 to a MySQL on RDS produces?

推荐答案

一般来说，这是 EBS 存储服务的价格.亚马逊声称对于 EBS 来说是这样的(预计成本部分):

In general it is a price for EBS storage service. Amazon claims something like this for EBS (section Projecting Costs):

例如，一个中型网站数据库的大小可能为 100 GB并期望在一个月内平均每秒进行 100 次 I/O.这将转化为每月 10 美元的存储成本(100 GB x0.10 美元/月)，以及每月大约 26 美元的请求成本(~2.6百万秒/月 x 100 I/O 每秒 * 每百万 I/O 0.10 USD).

As an example, a medium sized website database might be 100 GB in size and expect to average 100 I/Os per second over the course of a month. This would translate to $10 per month in storage costs (100 GB x $0.10/month), and approximately $26 per month in request costs (~2.6 million seconds/month x 100 I/O per second * $0.10 per million I/O).

如果你在 Linux 上有一个正在运行的应用程序，这里有一篇文章如何衡量 EBS 的成本:
