Elastic Cloud Server (ECS) Service Specific Terms
1. Definition
Service Cycle: A service cycle is a calendar month.
Total Time of Service Cycle per ECS is the total number of minutes in a Service Cycle for an ECS. Total Time of Service Cycle = Total number of days in a Service Cycle x 24 hours x 60 minutes.
ECS Unavailability is when the system logs of Elastic Cloud Servers (ECSs) (including FlexusX instances and ECSs on DeHs) show that ECS was inaccessible for one (1) or more consecutive minutes because of Huawei Cloud.
Unavailable Time per ECS is the total number of minutes that an ECS was unavailable in a Service Cycle.
Multi-AZ ECS Unavailability in One Region is the unavailability of ECSs in other availability zones (AZs) when the ECSs in one AZ in the same region are available.
Multi-AZ ECS Unavailability Time in One Region is the total number of minutes that the ECSs in other AZs experienced Multi-AZ ECS Unavailability in One Region within a Service Cycle.
Monthly Expenditure is your total expenditure for an ECS within a Service Cycle. If you pay for several months at a time, the Monthly Expenditure is calculated by dividing the total amount billed by the number of months the service was used.
2. Disclaimers
This SLA does not apply to any performance or availability issues caused by the following:
1) Data stored on local disks being lost due to damage to those disks or becoming unavailable due to an instance breakdown;
2) If your service does not have high availability (HA) capabilities and does not accept server replacement,BMS or ECS with local disks instance becomes unavailable during hardware repair;
3) Service unavailability caused by your own operations, for example, stopping or restarting an ECS, or detaching an EVS disk from an ECS using the console or APIs;
4) Services made unavailable due to unsupported software or drivers, third-party software or drivers that are not directly managed by Huawei Cloud, configuration errors, or hacker attacks;
5) Data, passwords, or other information getting lost or leaked due to improper maintenance or handling of confidential information;
6) Spot ECSs released because the bid price was lower than the market price or ECSs suspended or released due to payment in arrears;
7) Unavailability caused by a force majeure;
8) Unavailability caused by your operation errors or operations authorized by you;
9) Network faults, device faults, or configuration adjustment of non-Huawei devices;
10) Short-term server interruption or network unavailability caused by live migration (which is performed in advance to prevent server breakdown caused by hardware faults);
11) Unavailability caused by your failure to respond to Huawei Cloud notices on routine maintenance activities such as repair, maintenance, upgrades, and optimization of service platforms or related equipment, systems, and software.
3. Service Availability
Calculation formula for Service Availability Rate in each Service Cycle:
The ECS Service Availability Rate can be calculated by referring to the following formula:
1) Single ECS service availability (ECS availability within a given AZ and region)
Service Availability Rate per Service Cycle = (Total Time of a Service Cycle per ECS – Unavailable Time per ECS)/Total Time of Service Cycle per ECS x 100%.
2) Multi-AZ ECS service availability in one region (ECS availability in multiple AZs in a region)
Service Availability Rate per Service Cycle = (Total Time of a Service Cycle per ECS – Multi-AZ ECS Unavailability Time in One Region)/Total Time of Service Cycle per ECS x 100%.
Service Availability Rate Commitment
1) Huawei Cloud will use all commercially and technically reasonable efforts to ensure that the Service Availability Rate of a Single ECS (ECS availability within a given AZ and region) per Service Cycle is not lower than 99.975% and that the Multi-AZ ECS Availability Rate in One Region per Service Cycle is not lower than 99.995%. You are advised to deploy ECSs in at least two AZs in one region (if a given region has only one AZ, then deploy your ECSs in at least two regions) for a higher service availability rate. If you choose to deploy your ECSs in a single AZ in a given region, Huawei Cloud shall only promise a single ECS service availability (ECS availability within a given AZ and region) per Service Cycle.
2) ECS provides different deployment modes for your applications. You can deploy one or more applications on a single ECS, or you can deploy applications in active/standby or cluster mode on multiple ECSs. You have understood and agreed that different deployment modes deliver different levels of reliability. Choose an appropriate one to meet your requirements for service reliability. To prevent single points of failure (SPOFs) from affecting core services, you are advised not to deploy HA applications on a single ECS.
