Amazon OpenSearch Service (Successor to Amazon Elasticsearch Service) - Service Level Agreement for Amazon Web Services (Ningxia Region)

Last Updated: September 9, 2021

This Amazon OpenSearch Service - Service Level Agreement for Amazon Web Services (Ningxia Region) ("SLA") is a policy governing the use of the Amazon OpenSearch Service under the terms of the Western Cloud Data Customer Agreement for Amazon Web Services (Ningxia Region) (available at https://www.amazonaws.cn/agreement/ningxia and as updated from time to time, collectively with other agreements with us governing your use of our Services, the “Agreement”) between Ningxia Western Cloud Data Technology Co., Ltd. (“Western Cloud Data”, “us” or “we”) and you. This SLA applies separately to each account using Amazon OpenSearch Service. In the event of a conflict between the terms of this SLA and the terms of 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.

Service Commitment

We will use commercially reasonable efforts to make Multi-AZ domains on Amazon OpenSearch Service available with a Monthly Uptime Percentage of at least 99.9% during any monthly billing cycle (the "Service Commitment"). In the event Amazon OpenSearch Service does not meet the Monthly Uptime Percentage commitment, you will be eligible to receive a Service Credit as described below. The Service Commitment and Service Credits provided to you under this SLA will be provided to you only in connection with your use of Amazon OpenSearch Service from Amazon Web Services China (Ningxia) region. This SLA does not authorize you to receive any Service Commitment or Service Credits from any other Amazon Web Services regions.

Service Credits

Service Credits are calculated as a percentage of the charges paid by you for the Multi-AZ domain that did not meet the Monthly Uptime Percentage commitment in a billing cycle 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 Amazon OpenSearch Service payments otherwise due from you. At our discretion, we may issue the Service Credit to the bank 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 us. A Service Credit will be applicable and issued only if the credit amount for the applicable monthly billing cycle is greater than one Renminbi (¥1 Renminbi). 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 or non-performance or other failure by us to provide Amazon OpenSearch Service is the receipt of a Service Credit (if eligible) in accordance with the terms of this SLA.

Credit Request and Payment Procedures

To receive a Service Credit, you will need to submit a claim by opening a case in the Amazon Web Services 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:

(i) the words “SLA Credit Request” in the subject line;
(ii) the dates and times of each Unavailability incident you are claiming;
(iii) the names of the affected Multi-AZ domains; and
(iv) your Request logs that document the errors and corroborate 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 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 request occurred. Your failure to provide the request and other information as required above will disqualify you from receiving Service Credits.

Amazon OpenSearch Service SLA Exclusions

The Service Commitment does not apply to any unavailability, suspension or termination of Amazon OpenSearch Service, or any other Amazon OpenSearch Service 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 OpenSearch Service; (ii) that result from any voluntary actions or inactions from you or any third party; (iii) that result from insufficient storage and compute capacity provisioned to handle your workload; (iv) that result from you not following the best practices described in the Amazon OpenSearch Service Developer guide on the Amazon Web Services China Site; (v) that result from input data or operations not supported in the version of Elasticsearch or OpenSearch used on the Multi-AZ domain; (vi) that result from nodes belonging to burstable general-purpose instances such as T2 instances; (vii) caused by underlying Elasticsearch or OpenSearch software that lead to repeated failures while processing your Requests; (viii) that result from your usage of Elasticsearch or OpenSearch versions that are no longer under active development and maintenance; (ix) that result from your equipment, software or other technology and/or third party equipment, software or other technology (other than third party equipment within our direct control); or (x) arising from our suspension and termination of your right to use Amazon OpenSearch Service in accordance with the Agreement (collectively, the "Amazon OpenSearch Service 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

  • "Monthly Uptime Percentage" for a given Multi-AZ domain is calculated by subtracting from 100% the percentage of 5 minute intervals during the monthly billing cycle in which the Multi-AZ domain was Unavailable. If you have been running that Multi-AZ domain for only part of the month, your Multi-AZ domain is assumed to be 100% available for the portion of the month that it was not running. Monthly Uptime Percentage measurements exclude downtime resulting directly or indirectly from any Amazon OpenSearch Service SLA Exclusion.
  • “Multi-AZ domain” means an Amazon OpenSearch Service domain, where the nodes are deployed across two or more Availability Zones.
  • "Unavailable" and “Unavailability” mean that all Requests to the running Multi-AZ domain during a 5-minute interval fail with Errors. If you did not make any Requests in a given 5-minute interval, that interval is assumed to be 100% available.
  • A “Request” is a customer-initiated Indexing or Search operation as described in the Amazon OpenSearch Service Documentation on the Amazon Web Services China Site.
  • An “Error” is any Request that returns a 500 or 503 error code.
  • A "Service Credit" is a Renminbi credit, calculated as set forth above, that we may credit back to an eligible account.
