RDS for MySQL, RDS for PostgreSQL, RDS for SQL Server, and RDS for MariaDB Service Level Agreement
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

Service Credit: In the event Huawei Cloud does not meet the commitment on the Service Availability Rate specified in this SLA, you will be eligible to receive service credit as described below, which is the sole and exclusive remedy for any performance or availability issues for any Services under the Customer Agreement and this SLA.

The application must be filed within two (2) months after the end of the Service Cycle in which the incident that’s the subject of the claim occurred.
