Amazon Braket Service Level Agreement
Last Updated: May 4, 2022
This Amazon Braket Service Level Agreement (“SLA”) is a policy governing the use of Amazon Braket and applies separately to each account using Amazon Braket. In the event of a conflict between the terms of this SLA and the terms of the AWS Customer Agreement or other agreement with us governing your use of our Services (the “Agreement”), the terms and conditions of this SLA apply, but only to the extent of such conflict. Capitalized terms used herein but not defined herein shall have the meanings set forth in the Agreement.
This SLA applies only to the use of quantum computing simulators on Amazon Braket.
Service Commitment
AWS will use commercially reasonable efforts to make Amazon Braket available with a Monthly Uptime Percentage for each AWS region, during any monthly billing cycle, of at least 99.9% (the “Service Commitment”). In the event Amazon Braket does not meet the Service Commitment, you will be eligible to receive a Service Credit as described below.
Service Credits
Service Credits are calculated as a percentage of the total charges paid by you for the use of quantum computing simulators on Amazon Braket in the affected AWS region for the monthly billing cycle in which the Service Commitment was not met, in accordance with the schedule below:
Monthly Uptime Percentage |
Service Credit Percentage |
Less than 99.9% but greater than or equal to 99.0% |
10% |
Less than 99.0% but greater than or equal to 95.0% |
25% |
Less than 95.0% |
100% |
We will apply any Service Credits only against future payments for the use of quantum computing simulators on Amazon Braket otherwise due from you. At our discretion, we may issue the Service Credits to the credit card you used to pay for the billing cycle in which the unavailability occurred. Service Credits will not entitle you to any refund or other payment from AWS. Service Credits will be applicable and issued only if the credit amount for the applicable monthly billing cycle is greater than one dollar ($1 USD). Service Credits may not be transferred or applied to any other account. Unless otherwise provided in the Agreement, your sole and exclusive remedy for any unavailability, non-performance, or other failure by us to provide Amazon Braket is the receipt of Service Credits (if eligible) in accordance with the terms of this SLA.
Credit Request and Payment Procedures
To receive Service Credits, you will need to submit a claim by opening a case in the AWS Support Center. To be eligible, the credit request must be received by us by the end of the second billing cycle after which the incident occurred and must include:
- the words “SLA Credit Request” in the subject line;
- the billing cycle and AWS region(s) with respect to which you are claiming Service Credits, together with the Monthly Uptime Percentage for that AWS region for the billing cycle and the specific dates, times, and Availabilities for each 5-minute interval with less than 100% Availability in that AWS region throughout the billing cycle; and
- your Request logs that document the errors for your claimed outage (any confidential or sensitive information in these logs should be removed or replaced with asterisks).
If the Monthly Uptime Percentage of such credit request is confirmed by us and is less than the Service Commitment, then we will issue the Service Credits to you within one billing cycle following the month in which the credit request occurred. Your failure to provide the credit request and other information as required above will disqualify you from receiving Service Credits.
Amazon Braket SLA Exclusions
The Service Commitment does not apply to any unavailability, suspension, or termination of Amazon Braket, or any other Amazon Braket performance issues: (i) caused by factors outside of our reasonable control, including any force majeure event or Internet access or related problems beyond the demarcation point of Amazon Braket; (ii) that result from any actions or inactions by you (iii) that result from you not following the guidelines and best practices described in the Amazon Braket Documentation on the AWS Site; (iv) that result from your equipment, software or other technology; or (v) arising from our suspension or termination of your right to use Amazon Braket in accordance with the Agreement (collectively, the “Amazon Braket SLA Exclusions”). If availability is impacted by factors other than those explicitly used in our Monthly Uptime Percentage calculation, then we may issue a Service Credit considering such factors at our discretion.
Definitions
- “Availability” is calculated for each 5-minute interval as the percentage of Requests processed by Amazon Braket that do not fail with Errors. If you did not make any Requests in a given 5-minute interval, that interval is assumed to be 100% available.
- An “Error” is any Request that returns a 500 or 503 error code.
- “Monthly Uptime Percentage” for a given AWS region is calculated as the average of the Availability for all 5-minute intervals in a monthly billing cycle. Monthly Uptime Percentage measurements exclude downtime resulting directly or indirectly from any Amazon Braket SLA Exclusion.
- A “Request” is an invocation or cancellation of an Amazon Braket simulation by directly calling either the CreateQuantumTask or CancelQuantumTask APIs where the device ARN attribute in the API call references a quantum simulator (for example, "arn:aws:braket:::device/quantum-simulator/amazon/sv1").
- A “Service Credit” is a dollar credit, calculated as set forth above, that we may credit back to an eligible account.
Amazon Braket 服務水準協議
最後更新日期: 2022 年 5 月 4 日
本Amazon Braket 服務水準協議(下稱「SLA」),係規範Amazon Braket使用情形的政策,並且分別適用於使用 Amazon Braket 的各個帳戶。本 SLA 的條款如與 AWS 客戶協議或規範您對本公司服務使用情形的其他協議(下稱「本協議」)條款有相互牴觸者,應以本 SLA 之條款及條件為準,惟僅限該等相牴觸之處。本文使用但未予以定義之專用詞語,應具有本協議中規定的意義。
本SLA僅適用於使用Amazon Braket上的量子運算模擬器的情形。
服務承諾
AWS 應盡商業合理努力,為每個 AWS 區域提供Amazon Braket,並於任何每月帳單週期內,達到至少99.99%的每月正常運行時間百分比(下稱「服務承諾」)。Amazon Braket 如未能達成服務承諾,您有資格獲得下述之服務抵免額。
服務抵免額
服務抵免額係以未達成服務承諾的該月帳單週期內,您為受影響 AWS 區域使用 Amazon Braket 上的量子運算模擬器所支付之總費用的百分比計算,如下表所示:
每月正常運行時間百分比 |
服務抵免百分比 |
低於 99.9% 但大於或等於 99.0% |
10% |
低於 99.0% 但大於或等於 95.0% |
25% |
低於 95.0% |
100% |
我們僅會把服務抵免額用於扣抵您日後因使用 Amazon Braket 上的量子運算模擬器而應支付之款項。我們得經自行斟酌,決定把發生不可用狀況之帳單週期內的服務抵免額發放至您用於支付的信用卡。服務抵免額不會讓您獲得 AWS 的任何退款或其他付款。只有在所涉每月帳單週期的入帳金額超過 1 美元($1 USD)時,才會適用並發放服務抵免額。服務抵免額不得移轉或套用至任何其他帳戶。除本協議另有規定外,對於我們提供 Amazon Braket 時所發生之任何不可用或無法履行或其他無法供應之狀況,您可以採行之唯一救濟方式為依據本 SLA 條款獲得服務抵免額(如符合資格者)。
抵免額申請和付款程序
如欲獲得服務抵免額,您必須在AWS 支援中心開啟案件,提出請求主張。要符合抵免資格,我們必須在事件發生後第二個帳單週期結束前收到抵免申請,且必須包括以下資訊:
- 主旨行包含「SLA 抵免申請」的詞語;
- 您申請服務抵免額的帳單週期及 AWS 區域,以及該 AWS 區域在帳單週期內每月正常運行時間百分比及具體日期、時間及該AWS 區域在整個計費週期內每 5 分鐘間隔可用性不到 100% 的可用性;和
- 您的申請記錄檔,其中記載您主張發生營運中斷情形所涉及之錯誤(這些記錄檔所包含之任何機密或敏感性資訊,均應移除或以星號取代)。
該抵免額申請的每月正常運行時間百分比如經我們確認少於服務承諾者,我們會在抵免額申請提出月份後的一個帳單週期內,向您核發服務抵免額。如未能提供前述要求的抵免額申請資訊及其他資訊者,您便失去獲得服務抵免額的資格。
Amazon Braket SLA 除外事項
本服務承諾不適用於符合以下條件之任何 Amazon Braket 之不可用、暫停或終止情事,或其他任何 Amazon Braket 效能問題:(i) 逾越我們可合理控制之因素所導致者,包括任何不可抗力事件或網際網路存取情形,或超出 Amazon Braket 分界點的相關問題;(ii) 因您的任何作為或不作為所致者;(iii) 因您未遵循 AWS 網站上 Amazon Braket 文件所載之指南與最佳做法所導致之結果;(iv) 因您的設備、軟體或其他技術所導致;或 (v) 由於我們基於本協議暫停或終止您使用 Amazon Braket 之權利所導致者(統稱為「Amazon Braket SLA 除外事項」)。如果影響可用性的因素並非我們在每月正常運行時間百分比計算中明確使用的因素,則本公司可以自行決定是否基於該等因素發放服務抵免額。
定義
- 「可用性」係指在每 5 分鐘區間內,Amazon Braket 所處理請求並未因錯誤而失敗的百分比。如果您在既定的 5 分鐘間隔內並未發出任何請求,則該間隔假設為 100% 可用。
- 「錯誤」係指任何回傳 500 或 503 錯誤碼的請求。
- 任何 AWS 區域的「每月正常運行時間百分比」,係以每月帳單週期中所有五分鐘間隔可用性的平均值做計算。每月正常運行時間百分比測量排除因任何 Amazon Braket SLA 除外事項而直接或間接導致的停機時間。
- 「請求」係指透過直接呼叫 CreateQuantumTask 或CancelQuantumTask API,叫用或取消 Amazon Braket 模擬作業,其中 API 呼叫的裝置 ARN 屬性引用一個量子模擬器(例如:arn:aws:braket:::device/quantum-simulator/amazon/sv1)。
- 「服務抵免額」是按上述方式計算的美元抵免額,我們可能會把服務抵免額發放至符合條件的帳戶。
