InstanceType

String

Yes

The instance type.

To scale by instance type weight, specify both InstanceType and WeightedCapacity.

Capacity of ecs.c5.xlarge: 4

To meet the expected capacity, the system adds two ecs.c5.xlarge instances to the scaling group.

Instance types of this level provide stable performance and dedicated resources, and are suitable for business scenarios that require high stability. For more information, see Instance family overview. CreditEntryLevel: credit-based entry level (burstable instance types). CPU credits are used to ensure computing performance. Instance types of this level are suitable for business scenarios in which CPU utilization is usually low but suddenly increases. For more information, see Burstable instances.
