Creates a scaling configuration.
Description
Auto Scaling automatically scales out Elastic Compute Service (ECS) instances based on a scaling configuration. ECS instances can be configured in the following modes:
- InstancePatternInfo.N: intelligent configuration mode. In this mode, you need to only specify the number of vCPUs, memory size, instance family, and maximum price. The system selects an instance type that is provided at the lowest price based on your configurations to create ECS instances. This mode is available only for scaling groups that reside in virtual private clouds (VPCs). This mode helps reduce the failures of scale-out activities caused by insufficient inventory of instance types.
- InstanceType: In this mode, you must specify an instance type.
- InstanceTypes.N: In this mode, you must specify multiple instance types.
- InstanceTypeOverride.N: In this mode, you must specify multiple instance types and specify weights for the instance types.
- Cpu and Memory: In this mode, you must specify the number of vCPUs and the memory size. Auto Scaling determines a set of available instance types based on factors such as I/O optimization requirements and zones. Then, Auto Scaling preferentially creates ECS instances of the instance type that is provided at the lowest price. This mode is available only if the Scaling Policy parameter is set to Cost Optimization Policy and no instance type is specified in the scaling configuration.
