Service Limits

Last updated: 2022-07-29 14:42:51

Auto Scaling is now available in all regions except edge-server regions. The following table details the use limits of this feature:

Limit Type Remarks
One user under one region
  • Up to 50 launch configurations can be created.
  • Up to 50 scaling groups can be created.
  • The maximum number of CVM instances that can be created depends on your CVM quota. For more information, see Purchase Limits for Pay-as-You-Go CVM Instances.
A scaling group
  • There can be only one launch configuration.
  • Up to 2,000 CVM instances can be auto-scaled.
  • Up to 100 scaling policies and 10 scheduled actions can be created.
  • Up to 5 notifications can be created.
  • Up to 10 lifecycle hooks can be created.
  • The number of CVMs in all scaling groups cannot exceed the maximum number of IP addresses that the VPC subnet can provide.
  • Currently, Auto Scaling does not support scaling up, which means it cannot automatically scale up the CPU, memory, or bandwidth of CVM instances.
  • Auto Scaling and launch configurations are services supported at the region level. Therefore, you can only launch or terminate CVM instances in the same region.
  • A scaling group and its associated CLB instances (in the case of a cross-region CLB instance, its backend VPC) must be in the same network environment (the VPC instance or the basic network in the same region).
