Managing your costs with AWS Budgets

AWS Budgets 使您能够规划服务使用情况、服务成本以及实例预留。预算为您提供一种方法,用以查看以下信息:

  • How close your plan is to your budgeted amount or to the free tier limits

  • Your usage to date, including how much you have used of your Reserved Instances (RIs)

  • Your current estimated charges from AWS and how much your predicted usage will incur in charges by the end of the month

  • How much of your budget has been used

AWS Budgets 信息每天最多更新三次。更新通常在上次更新后 8 到 12 小时之间进行。预算跟踪您未混合的成本、订阅、退款和 RI。您可创建下列类型的预算:

  • Cost budgets – Plan how much you want to spend on a service.

  • Usage budgets – Plan how much you want to use one or more services.

  • RI utilization budgets – Define a utilization threshold and receive alerts when your RI usage falls below that threshold. This lets you see if your RIs are unused or under-utilized.

  • RI coverage budgets – Define a coverage threshold and receive alerts when the number of your instance hours that are covered by RIs fall below that threshold. This lets you see how much of your instance usage is covered by a reservation.

  • 节省计划 utilization budgets – Define a utilization threshold and receive alerts when the usage of your 节省计划 falls below that threshold. This lets you see if your 节省计划 are unused or under-utilized.

  • 节省计划 coverage budgets – Define a coverage threshold and receive alerts when your 节省计划 eligible usage that is covered by 节省计划 fall below that threshold. This lets you see how much of your instance usage is covered by 节省计划.

您可以创建 20,000 每个账户的预算或 AWS Organizations 主账户。对于常规账户,您的前62天预算日可免费提供。每额外的预算日成本 $0.02.62预算天数等同于您每月的前两个预算。对于合并计费系列中的账户,可以跨多个账户分配62个预算天数。例如,对于 62 个账户,如果每个账户中有 1 个预算,则对于每笔预算,每个月的第一天免费。该月剩余的天数将按照每笔预算每天 $.02 收取费用。您可以设置可选通知,用以警告您超过或预测会超过预算的成本或使用量预算金额,或低于您的 RI 预算的预算金额。通知可发送到 Amazon SNS 主题和/或电子邮件地址。有关更多信息,请参阅 Creating an Amazon SNS topic for budget notifications。AWS免费层次使用警报 AWS 为您提供预算,不计入预算限制。 AWS 提供预算仅供参考。您不能使用预算停止或控制其他服务。

如果您在组织中使用整合账单,并且您拥有主账户,则可以使用 IAM 策略控制成员账户对预算的访问。默认情况下,成员账户的所有者可以创建各自的预算,但不能创建或编辑其他用户的预算。您可以创建 IAM 具有允许他们在特定帐户中创建、编辑、删除或读取预算的权限。但是,我们不支持跨账户使用。预算仅对有权访问创建预算的账户的用户可见,并且只能访问预算本身。例如,主账户可以创建跟踪特定成员账户成本的预算,但成员账户只有在获得了主账户访问权限时才能查看相同的预算。有关更多信息,请参阅 Overview of managing access permissions。) 有关 AWS Organizations 的更多信息,请参阅AWS Organizations 用户指南

注意

在您产生费用和从 AWS Budgets 收到有关此费用的通知之间可能存在延迟。这是由于使用 AWS 资源和对该资源使用量进行计费之间存在延迟。您可能会在 AWS Budgets 通知您之前产生超过预算通知阈值的额外费用或使用量。
