Prior Version(s) of Amazon Lambda Service Level Agreement for Amazon Web Services for (Ningxia Region)

This Amazon Lambda Service Level Agreement for Amazon Web Services (Ningxia Region) (“SLA”) is a policy governing the use of Amazon Lambda (“Lambda”) under the terms of the Western Cloud Data Customer Agreement for Amazon Web Services (Ningxia Region) (the “Agreement”, available at http://www.amazonaws.cn/agreement/ningxia and as updated from time to time) between Ningxia Western Cloud Data Technology Co., Ltd. (“Western Cloud Data”, “us” or “we”) and you. This SLA applies separately to each account using Lambda from Amazon Web Services China (Ningxia) region. Unless otherwise provided herein, this SLA is subject to the terms of the Agreement and capitalized terms will have the meaning specified in the Agreement. We reserve the right to change the terms of this SLA in accordance with the Agreement.

We will use commercially reasonable efforts to make Lambda available with a Monthly Uptime Percentage (defined below), during any monthly billing cycle, of at least 99.95% (the “Service Commitment”). In the event Lambda does not meet the Service 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 the Included Products and Services 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.

• A “Service Credit” is a Renminbi credit, calculated as set forth below, that we may credit back to an eligible account.
• “Monthly Uptime Percentage” 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 Lambda SLA Exclusion (defined below).
• “Availability” is calculated for each 5-minute interval as the percentage of Requests (defined below) processed by Lambda that do not fail with Errors (defined below) and relate solely to the provisioned Amazon Lambda functions. If you did not make any Requests in a given 5-minute interval, that interval is assumed to be 100% available.
• “Request” is an invocation of a Lambda function by directly calling the invoke API or triggered by a supported event source.
• An “Error” is any Request that returns a 500 or 503 error code.
  

Service Credits are calculated as a percentage of the following charges paid by you for Lambda for the monthly billing cycle in which the Monthly Uptime Percentage fell within the ranges set forth in the table below:

We will apply any Service Credits only against future Lambda payments otherwise due from you. Service Credits will not entitle you to any refund or other payment from us. Service Credits 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 Lambda is the receipt of Service Credits (if eligible) in accordance with the terms of this SLA.

To receive Service Credits, 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 billing cycle with respect to which you are claiming Service Credits, together with the Monthly Uptime Percentage for the billing cycle and the specific dates, times, and Availabilities for each 5-minute interval with less than 100% Availability throughout the billing cycle;
iii. 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.

The Service Commitment does not apply to any unavailability, suspension or termination of Lambda, or any other Lambda performance including but not limited to 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 Lambda;
ii. that result from any voluntary actions or inactions from you or any third party (e.g. scaling of provisioned capacity, misconfiguring security groups, VPC configurations or credential settings, disabling encryption keys or making the encryption keys inaccessible, etc.);
iii. that result from you not following the best practices described in the Lambda User Guide on the Amazon Web Services China Site;
iv. 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);
v. that result from any maintenance as provided for pursuant to the Agreement; or
vi. arising from our suspension and termination of your right to use Lambda in accordance with the Agreement (collectively, the “Lambda 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.
