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.

GaussDB for MySQL Service Specific Terms

1. Definition

Service Unavailability means the GaussDB(for MySQL) system log shows that a DB instance was inaccessible for one (1) or more consecutive minutes because of HUAWEI CLOUD. Duration of the inaccessibility and inability that lasts for shorter than one (1) minute shall not be included.

2. Disclaimers

Service unavailability caused by the following situations shall not be counted in the service unavailability period:

1) Customer operations, such as rebooting, deleting, or restoring GaussDB(for MySQL) instances through the console or APIs;

2) Network faults, device faults, or configuration adjustment of non-Huawei devices;

3) Faults that occur due to single-AZ deployment, instead of multi-AZ deployment;

4) Hacker attacks on customer applications;

5) Planned system maintenance, such as cutover, maintenance, upgrade, and fault drills, of which Huawei Cloud has notified the customer in advance;

6) Data (including passwords) leakage or loss due to improper maintenance of the customer;

7) Operations authorized by the customer or any misjudgment in operations;

8) Customer failure to comply with GaussDB(for MySQL) documentation or recommendations;

9) Service interruptions caused by insufficient vCPUs, memory, storage, and maximum number of connections of a DB instance or proxy instance due to heavy workloads of the customer;

10) Faults caused by open-source community bugs or other non-Huawei Cloud issues;

11) Service suspension or termination due to the customer's breach of service clauses (such as arrears);

12) Customer failure to rectify known problems or risks which Huawei Cloud has notified them of;

13) Other force majeure factors.

3. Service Availability

Service Availability Rate in Each Service Cycle calculation formula:

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

Service Availability Rate commitment:

HUAWEI CLOUD will use commercially and technically reasonable efforts to make the Service Availability Rate of GaussDB(for MySQL) per Service Cycle be no less than 99.99%.

Remarks: HUAWEI CLOUD cannot ensure the high availability of a single-node DB instance (with a primary node or a HTAP read replica) because the instance is deployed on only a single server.

4. Service Credit

If we fail to meet the commitment above on GaussDB(for MySQL) Service Availability Rate, HUAWEI CLOUD will provide you with service credit as follows.

Service Availability Rate

Service Credit

99% ≤ Service Availability Rate < 99.99%

10% of Monthly Service Fee

95% ≤ Service Availability Rate < 99%

25% of Monthly Service Fee

Service Availability Rate < 95%

100% of Monthly Service Fee
