購買保留項目Buy a reservation

Azure 保留可協助您藉由承諾多項 Azure 資源一年或三年期的方案來節省成本。Azure Reservations help you save money by committing to one-year or three-years plans for many Azure resources. 在您輸入承諾用量以購買保留之前,請務必先參閱下列各節,以做好購買的準備。Before you enter a commitment to buy a reservation, be sure to review the following sections to prepare for your purchase.

誰可以購買保留Who can buy a reservation

若要購買方案,您必須具備 Enterprise (MS-AZR-0017P 或 MS-AZR-0148P) 或隨用隨付訂用帳戶 (MS-AZR-0003P 或 MS-AZR-0023P) 或 Microsoft 客戶合約訂用帳戶的訂用帳戶擁有者角色。To buy a plan, you must have a subscription owner role in an Enterprise (MS-AZR-0017P or MS-AZR-0148P) or Pay-As-You-Go subscription (MS-AZR-0003P or MS-AZR-0023P) or Microsoft Customer Agreement subscription. 雲端解決方案提供者可使用 Azure 入口網站或 合作夥伴中心 來購買 Azure 保留。Cloud solution providers can use the Azure portal or Partner Center to purchase Azure Reservations.

Enterprise 合約 (EA) 客戶可藉由在 EA 入口網站中停用 [新增保留執行個體] 選項,以限制對 EA 管理員的購買。Enterprise Agreement (EA) customers can limit purchases to EA admins by disabling the Add Reserved Instances option in the EA Portal. EA 管理員必須是至少一個 EA 訂用帳戶的訂用帳戶擁有者,才能購買保留。EA admins must be a subscription owner for at least one EA subscription to purchase a reservation. 當企業想要讓中央小組購買不同成本中心的保留時,此選項非常有用。The option is useful for enterprises that want a centralized team to purchase reservations for different cost centers. 購買之後,中央小組可以將成本中心擁有者新增至保留。After the purchase, centralized teams can add cost center owners to the reservations. 然後,擁有者可以將保留範圍設定為其訂用帳戶。Owners can then scope the reservation to their subscriptions. 中央小組不需要擁有購買保留之處的訂用帳戶擁有者存取權。The central team doesn't need to have subscription owner access where the reservation is purchased.

保留折扣僅適用於與透過 Enterprise、雲端解決方案提供者 (CSP)、Microsoft 客戶合約購買的訂用帳戶相關聯的資源,以及採用隨用隨付費率的個別方案。A reservation discount only applies to resources associated with subscriptions purchased through Enterprise, Cloud Solution Provider (CSP), Microsoft Customer Agreement and individual plans with pay-as-you-go rates.

設定保留範圍Scope reservations

您可以將保留範圍設定為訂用帳戶或資源群組。You can scope a reservation to a subscription or resource groups. 設定保留範圍時會選取保留節省成本的適用之處。Setting the scope for a reservation selects where the reservation savings apply. 當您將保留範圍設定為資源群組時,保留折扣僅適用於該資源群組,而不會適用於整個訂用帳戶。When you scope the reservation to a resource group, reservation discounts apply only to the resource group—not the entire subscription.

保留範圍設定選項Reservation scoping options

視您的需求而定,您有三個選項可設定保留範圍:You have three options to scope a reservation, depending on your needs:

  • 單一資源群組範圍 — 只會將保留折扣套用至所選資源群組中的相符資源。Single resource group scope—Applies the reservation discount to the matching resources in the selected resource group only.
  • 單一訂用帳戶範圍 — 會將保留折扣套用至所選訂用帳戶中的相符資源。Single subscription scope—Applies the reservation discount to the matching resources in the selected subscription.
  • 共用範圍 — 會將保留折扣套用至計費內容中合格訂用帳戶的相符資源。Shared scope—Applies the reservation discount to matching resources in eligible subscriptions that are in the billing context. 針對 Enterprise 合約客戶,計費內容為註冊。For Enterprise Agreement customers, the billing context is the enrollment. 針對 Microsoft 客戶合約客戶,計費範圍是帳單設定檔。For Microsoft Customer Agreement customers, the billing scope is the billing profile. 針對使用隨用隨付費率的個別訂用帳戶,計費範圍是帳戶管理員所建立的所有合格訂用帳戶。For individual subscriptions with pay-as-you-go rates, the billing scope is all eligible subscriptions created by the account administrator.

在您的使用量上套用保留折扣時,Azure 會依照下列順序處理保留:While applying reservation discounts on your usage, Azure processes the reservation in the following order:

  1. 範圍設定為資源群組的保留Reservations that are scoped to a resource group
  2. 單一範圍保留Single scope reservations
  3. 共用範圍保留Shared scope reservations

您一律可以在購買保留之後變更範圍。You can always update the scope after you buy a reservation. 若要這麼做,請移至保留,按一下 [設定] ,然後重新設定保留範圍。To do so, go to the reservation, click Configuration, and rescope the reservation. 重新設定保留範圍不算是商業交易。Rescoping a reservation isn't a commercial transaction. 您的保留期限不會變更。Your reservation term isn't changed. 如需有關更新範圍的詳細資訊,請參閱在購買保留後更新範圍For more information about updating the scope, see Update the scope after you purchase a reservation.

保留折扣適用於下列合格訂用帳戶和供應項目類型。Reservation discounts apply to the following eligible subscriptions and offer types.

購買保留Purchase reservations

您可以從 Azure 入口網站、API、PowerShell、CLI 來購買保留。You can purchase reservations from Azure portal, APIs, PowerShell, CLI. 當您準備好要購買保留時,請閱讀下列適用的文章:Read the following articles that apply to you when you're ready to make a reservation purchase:

購買或每月付款的 Azure 保留Buy reservations with monthly payments

您可以透過每月付款的方式購買 Azure 保留。You can pay for reservations with monthly payments. 不同於需支付全額的預先購買,每月付款選項會將保留的總費用平均分配至期限中的每一個月份。Unlike an up-front purchase where you pay the full amount, the monthly payment option divides the total cost of the reservation evenly over each month of the term. 預付和每月付款的保留總費用是相同的,當您選擇按月支付時,您不需要支付任何額外費用。The total cost of up-front and monthly reservations is the same and you don't pay any extra fees when you choose to pay monthly.

如果是使用 Microsoft 客戶合約 (MCA) 購買保留,則您的月付金額可能會依當地貨幣的當月市場匯率而異。If reservation is purchased using Microsoft customer agreement (MCA), your monthly payment amount may vary, depending on the current month's market exchange rate for your local currency.

每月付款不適用於:Databricks、SUSE Linux 保留、Red Hat 方案和 Azure Red Hat OpenShift Compute。Monthly payments are not available for: Databricks, SUSE Linux reservations, Red Hat Plans and Azure Red Hat OpenShift Compute.

檢視已支付的款項View payments made

您可以使用 API、使用量資料和成本分析來檢視已支付的款項。You can view payments that were made using APIs, usage data, and in cost analysis. 針對每月付款的保留,使用量資料和保留費用 API 中的頻率值會顯示為定期For reservations paid for monthly, the frequency value is shown as recurring in usage data and Reservation Charges API. 針對預先付款的保留,此值會顯示為一次性For reservations paid up front, the value is shown as onetime.

成本分析會在預設檢視中顯示每月的購買。Cost analysis shows monthly purchases in the default view. 在 [費用類型] 上套用 [購買] ,以及在 [頻率] 上套用 [定期] 來進行篩選,即可查看所有購買。Apply the purchase filter to Charge type and recurring for Frequency to see all purchases. 若只要檢視保留,請篩選 [保留] 。To view only reservations, apply a filter for Reservation.

在成本分析中顯示保留購買費用的範例

交換和退款Exchange and refunds

就像其他保留一樣,您可以針對以每月計費購買的保留進行退款或交換。Like other reservations, you can refund or exchange reservations purchased with monthly billing.

當您交換每月付款的保留時,新購買項目的總存留期費用應大於退回保留而取消的剩餘款項。When you exchange a reservation that's paid for monthly, the total lifetime cost of the new purchase should be greater than the leftover payments that are canceled for the returned reservation. 交換並不沒有其他限制或費用。There are no other limits or fees for exchanges. 您可以交換預先付款的保留,改為購買每月計費的新保留。You can exchange a reservation that's paid for up front to purchase a new reservation that's billed monthly. 不過,新保留的存留期值應該大於退回保留的比例分配值。However, the lifetime value of the new reservation should be greater than the prorated value of the reservation being returned.

如果您取消每月付款的保留,已取消的未來付款將會累積到 50,000 美元的退款限制。If you cancel a reservation that's paid for monthly, canceled future payments accrue towards the $50,000 USD refund limit.

如需有關交換和退款的詳細資訊,請參閱 Azure 保留的自助式交換和退款For more information about exchange and refunds, see Self-service exchanges and refunds for Azure Reservations.
