This article explores estimating the AWS RDS SQL Server cost so that you can plan resources accordingly.
本文探讨了估算AWS RDS SQL Server成本的方法，以便您可以相应地计划资源。
介绍 (Introduction)
Amazon is a leading cloud solution provider and provides relational database service (RDS) for various databases such as Microsoft SQL Server, Oracle, PostgreSQL, MariaDB, MySQL and Amazon Aurora. We have explored various articles for AWS RDS SQL Server on SQLShack.
亚马逊是领先的云解决方案提供商，并为各种数据库（例如Microsoft SQL Server，Oracle，PostgreSQL，MariaDB，MySQL和Amazon Aurora）提供关系数据库服务（RDS）。 我们在SQLShack上浏览了有关AWS RDS SQL Server的各种文章。
Suppose we require a new RDS instance for our usage. In the planning phase, we need to consider the compute resources, storage, usage, availability requirements for RDS. Another useful requirement is cost analysis. Amazon provides a cost-effective model for you and charges only for the hours you use the RDS service. Once you stop the RDS DB instance, it does not charge anything to you. It is always a good idea to estimate the costs of the RDS instance during planning for it.
假设我们需要一个新的RDS实例来使用。 在规划阶段，我们需要考虑RDS的计算资源，存储，使用情况和可用性要求。 另一个有用的要求是成本分析。 Amazon为您提供了一种经济高效的模型，并且仅按您使用RDS服务的小时数收费。 停止RDS数据库实例后，它不会向您收取任何费用。 在规划RDS实例的成本时，始终建议一个好主意。
We get estimate RDS instance cost in two ways:
我们通过两种方式估算RDS实例成本：
- AWS RDS console AWS RDS控制台
- Simple Monthly Calculator 简单的每月计算器
Let’s look at both ways of estimating RDS costs.
让我们看一下估算RDS成本的两种方法。
使用RDS控制台的AWS RDS SQL Server成本估算 (AWS RDS SQL Server cost estimates using RDS console)
In the article AWS RDS SQL Server – Launching a new database instance, we go through RDS instance configuration and you should go through it before reading this article.
在“ AWS RDS SQL Server –启动新数据库实例”一文中 ，我们介绍了RDS实例配置，在阅读本文之前，您应该先进行配置。
In the create database wizard, select the required database engine, edition, version, templates, storage type, allocated space and provisioned IOPS, availability & durability for viewing the estimated cost of the RDS instance.
在创建数据库向导中，选择所需的数据库引擎，版本，版本，模板，存储类型，分配的空间和预配置的IOPS，可用性和持久性，以查看RDS实例的估计成本。
Let’s examine a few RDS SQL instance configuration and their estimated costs:
让我们检查一些RDS SQL实例配置及其估计成本：

10000 |
You can see the estimated monthly cost for the above configuration is 1707.58 USD:
您可以看到上述配置的估计每月成本为1707.58 USD：
Now, let’s change the DB instance class to db.m5.16xlarge (64 vCPU, 256 GiB RAM, EBS 10000 Mbs), and it changes AWS RDS SQL Server cost (estimated) to 27286.78 USD:
现在，让我们将数据库实例类更改为db.m5.16xlarge（64 vCPU，256 GiB RAM，EBS 10000 Mbs），并将AWS RDS SQL Server成本（估计值）更改为27286.78 USD：
In the above configuration, we used the dev template. If we change the template to production, the price will be higher, 54671.46 USD:
在以上配置中，我们使用了dev模板。 如果我们将模板更改为生产，则价格会更高，54671.46 USD：
In the above estimates, you will be charged for Multi-AZ standby instance. By default, if we use the production template, AWS recommends multi-AZ deployments for high availability purposes and enables it automatically for you. It also charges for the provisioned IOPS in the production template configuration.
在上述估算中，您需要为多可用区备用实例支付费用。 默认情况下，如果我们使用生产模板，则AWS建议出于高可用性目的进行多可用区部署，并自动为您启用它。 它还对生产模板配置中的预配置IOPS收费。
In the production instance, you will need a bigger storage size as well. The above estimates are for the 20 GiB storage that is not suitable for the production instance. Now, modify the required storage to 10000 GiB and storage prices increases as shown below. It charges 1280 USD for the 10000 GiB storage for the RDS instance:
在生产实例中，您还将需要更大的存储空间。 以上估计是针对不适合生产实例的20 GiB存储的。 现在，将所需的存储空间修改为10000 GiB，存储空间价格将增加，如下所示。 对于RDS实例的10000 GiB存储，它将收取1280 USD：
We should plan for the required IOPS for the RDS instance to get better IO throughput. The following estimates are for the 20000 IOPS, while the rest of the configuration remains the same. It is charged 2000 USD for the provisioned IOPS:
我们应该为RDS实例规划所需的IOPS，以获得更好的IO吞吐量。 以下估算值适用于20000 IOPS，其余配置保持不变。 预置的IOPS收费2000美元：
In this method, we estimate an RDS instance cost for an individual instance, and you need access to the AWS console.
在这种方法中，我们估计单个实例的RDS实例成本，并且您需要访问AWS控制台。
适用于AWS RDS SQL Server的AWS简单每月计算器 (AWS Simple Monthly Calculator for AWS RDS SQL Server cost)
Suppose you do not have access to the AWS console, and you are considering the cost of managed database instances for various cloud solution providers. In this case, the AWS Simple Monthly Calculator comes in handy.
假设您无权访问AWS控制台，并且正在考虑各种云解决方案提供商的托管数据库实例的成本。 在这种情况下，AWS简单月度计算器会派上用场。
You do not need access to the AWS console for using this tool. It is a web-based tool in which you can enter your requirements, and you get monthly estimates for the RDS resources.
您无需访问AWS控制台即可使用此工具。 它是一个基于Web的工具，您可以在其中输入需求，并且可以每月获取RDS资源的估算值。

Click on the highlighted tab(the Estimate of your monthly bill tab) to get the breakdown of the estimates:
点击突出显示的标签（您每月帐单的估算值标签）以获取估算明细：
Now suppose we require 5 instances of RDS instances with similar configuration. Specify the number of instances in the DB instances tab, and you get the estimated price as shown below:
现在假设我们需要5个具有类似配置的RDS实例。 在“数据库实例”选项卡中指定实例数，您将获得估计价格，如下所示：
You can see a breakdown of the total costs:
您可以查看总费用明细：
In any organization, we need multiple database environments such as production, development and staging. Each environment might differ in terms of computing resources as well as storage requirements. For example, a production instance has higher compute resources than other environments.
在任何组织中，我们都需要多个数据库环境，例如生产，开发和登台。 每个环境在计算资源和存储要求方面可能有所不同。 例如，生产实例比其他环境具有更高的计算资源。
We can calculate the total estimated cost of the RDS infrastructure using this simple monthly calculator at a single place. In the following table, we have calculated an estimated price for the 5 production, 2 development and 2 staging RDS instances.
我们可以在一个地方使用这个简单的每月计算器来计算RDS基础架构的总估算成本。 在下表中，我们计算了5个生产，2个开发和2个暂存RDS实例的估计价格。
