This topic describes instance families that do not support advanced VPC features.

Advanced VPC features include network ACLs, routing tables, and flow logs. For more information, see Network ACL overview, Route table overview, and Flow log overview.

Restrictions of advanced VPC features on ECS instances:
  • Instance creation: If advanced features are enabled on a VPC, you cannot create instances of instance families in the following table within the VPC.
  • Instance upgrade or downgrade: If the instance type of an ECS instance supports advanced features and those advanced features are enabled on the corresponding VPC, the instance cannot be changed to an instance that belongs to instance families in the following table. These methods to change instances include upgrading, downgrading, renewal and downgrading, and changing instance types.

When you enable advanced features on a VPC, the system automatically detects the instances within the VPC that need to be upgraded or downgraded. Then you can upgrade or downgrade these instances. For more information, see Change the instance type of a pay-as-you-go instance or Upgrade configurations of subscription instances.

Only the following instance families do not support advanced VPC features.
