The best practices for change management help you check the stability of cloud resources from the perspective of change management. This helps identify potential risks in advance and improve stability and O&M efficiency. This topic describes the default rules in the best practices for change management.
Rule name | Description |
Checks whether the snapshot creation time that you specified for each automatic snapshot policy falls in a specified time range. If so, the evaluation result is Compliant. When a snapshot is being created for an Elastic Block Storage (EBS) device, the I/O performance of the device degrades by up to 10%. This can result in a transient I/O speed decrease. We recommend that you create automatic snapshots during off-peak hours. | |
Checks whether the auto snapshots of ECS instances are retained for a period longer than or equal to the specified number of days. If so, the evaluation result is Compliant. Default value: 7. | |
Checks whether the maintenance period of each RDS instance matches one of the specified time ranges. If so, the evaluation result is Compliant. If the peak hours of your business overlap with the maintenance period, your business may be affected. | |
Checks whether the maintenance period of each AnalyticDB cluster falls in a specified time range. If so, the evaluation result is Compliant. | |
