Constraints and Limitations

Notes

Do not use Huawei Cloud resources for black market or perform activities that violate laws and regulations or Huawei security requirements. If you violate related requirements, your accounts will be restricted or frozen.
When your Huawei Cloud account is restricted or frozen or your cloud phones are retained, the use of cloud phones will be restricted. You need to handle these issues in advance to avoid service interruptions.
- If your Huawei Cloud account is restricted due to insufficient balance, you cannot perform operations, such as restarting the cloud phones, replacing images, or pushing files, on cloud phones.
- If your Huawei Cloud account is in arrears and frozen, you cannot perform operations, such as restarting the cloud phones, replacing images, or pushing files, on cloud phones.
- If your cloud phones enter the retention period because they are in arrears or have not been renewed upon expiration, the cloud phones will be frozen and cannot be used.
Cloud phone servers of the physical.kg1.4xlarge, physical.rx2.32xlarge.4, and physical.rx3.32xlarge.4 series use pay-per-use Elastic Volume Service (EVS) disks for storage. Fees are charged by hour in real time. You need to ensure that your account balance is sufficient to prevent resource freezing caused by account arrears.
You need to keep the access key of the cloud phone secure and exercise caution when selecting the open access port of the cloud phone to ensure security.
Cloud phone severs of the physical.rx1.xlarge series use local disks to store data. You can periodically back up important data.
