Huawei Cloud Service Level Agreement General Terms

This Service Level Agreement (this “SLA”) is an integral part of your Huawei Cloud Customer Agreement (the “Customer Agreement”). Capitalized terms used in this SLA are as defined in the Customer Agreement unless otherwise stated in this SLA. Should there be any difference between this SLA and the Customer Agreement, this SLA shall prevail.

Huawei Cloud may modify the terms of this SLA from time to time, and this SLA is still effective for the period you already purchased; however, if you extend your period, the modified SLA will apply. If you disagree with the modified SLA, you may cease using the Services.

General Terms

1. Definitions

“Service Cycle” means a natural month.

“Total Time of Service Cycle” means the total minutes during every Service Cycle.

“Service Unavailable” will be defined for each Service in the Service Specific Terms thereafter. Service Unavailable does not include the situation that Cloud Service is unavailable due to the disclaimers described below and disclaimers in the following service specific terms.

“Service Unavailable Duration” means all the time when the Service is unavailable during a Service Cycle. If the duration is less than one month, it is still regarded as one month. Service Unavailable Duration cannot be calculated more than once. Every Service Unavailable Duration cannot be calculated again after the compensation being applied for.

“Service Availability” means during a Service Cycle, the service available percentage per Service Cycle achieved by the Cloud Service given in this SLA.

“Monthly Service Fee” means service fees paid by customers for the Services in a Service Cycle. For example, if the customer pays the service fee of several months at a time, the Monthly Service Fee is calculated as the total service fees paid divided by the total number of month.

2. Service Credit

FunctionGraph Service Specific Terms

1. Definition

Service Unavailable is a situation where the error rate of FunctionGraph is greater than 5% within five (5) minutes. The Service Unavailable Duration is calculated by multiplying the error rate by five minutes. Error rates less than 5% will be excluded.

Error Rate is calculated by dividing the number of failed requests into the total number of valid requests in five minutes.

Failed Requests are those responded with HTTP status code 500 or 503 (not custom ones in function code) due to internal errors.

2. Disclaimers

In addition to the unavailability issues described in general terms, unavailability resulting from the following issues is not included as part of the Service Unavailable Duration:

1) Requests restricted by flow control due to quota exhaustion;

2) Identity verification or authentication failed, or account in arrears;

3) Non-function request failure;

4) Custom status code 500 or 503 returned;

5) Errors or timeouts caused by users' own function code;

6) Requests failed to reach the server due to non-FunctionGraph reasons.

3. Service Availability

Calculation formula for Service Availability Rate in each Service Cycle:

Service Availability Rate in each Service Cycle = (Total Time of Service Cycle - Service Unavailable Duration)/Total Time of Service Cycle x 100%.

Service Availability Rate commitment:

Huawei Cloud will make commercially and technically reasonable efforts to ensure that the Service Availability Rate of FunctionGraph per Service Cycle is not less than 99.95%.

4. Service Credit

If FunctionGraph fails to meet the preceding commitment, Huawei Cloud will provide you service credit as shown in the following table.
