# Auto Scaling operations All 25 listed operations are implemented. Back to [Auto Scaling](/docs/services/autoscaling/index.md). ## Summary | Category | ✅ Supported | | --- | --- | | Operations | 25 | --- ## Endpoints ### Operations | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `CreateAutoScalingGroup` | ✅ Supported | Reconciles: launches EC2 instances to DesiredCapacity from a LaunchConfiguration or a LaunchTemplate, resolved through EC2 at create time. A group naming neither AvailabilityZones nor VPCZoneIdentifier, and VPCZoneIdentifier subnets outside AvailabilityZones, are AWS's ValidationError; given only subnets, the zones are derived from them. MixedInstancesPolicy and InstanceId are refused with 501 | | | `UpdateAutoScalingGroup` | ✅ Supported | Min/max/desired changes re-converge the group; desired outside min/max, VPCZoneIdentifier subnets outside AvailabilityZones, and an update leaving the group with neither AvailabilityZones nor VPCZoneIdentifier, are AWS's ValidationError. Setting either launch source clears the other | | | `DescribeAutoScalingGroups` | ✅ Supported | Reports the real converged instance set with LifecycleState, HealthStatus, AvailabilityZone and ProtectedFromScaleIn, and the group's LaunchTemplate when it has one | | | `DeleteAutoScalingGroup` | ✅ Supported | ResourceInUse while instances remain unless ForceDelete; ForceDelete terminates them | | | `SetDesiredCapacity` | ✅ Supported | Launches or terminates instances to converge; out-of-range values return AWS's ValidationError | | | `TerminateInstanceInAutoScalingGroup` | ✅ Supported | Terminates the EC2 instance and records the scaling activity; honours ShouldDecrementDesiredCapacity | | | `CreateLaunchConfiguration` | ✅ Supported | ImageId/InstanceType/SecurityGroups drive RunInstances at launch time | | | `DescribeLaunchConfigurations` | ✅ Supported | | | | `DeleteLaunchConfiguration` | ✅ Supported | ResourceInUse while a group still references it | | | `PutScalingPolicy` | ✅ Supported | SimpleScaling and StepScaling execute for real; TargetTrackingScaling and PredictiveScaling are refused with 501 | | | `DescribePolicies` | ✅ Supported | | | | `DeletePolicy` | ✅ Supported | | | | `ExecutePolicy` | ✅ Supported | Applies the policy's adjustment to DesiredCapacity, honouring cooldown and MinAdjustmentMagnitude | | | `PutLifecycleHook` | ✅ Supported | Really pauses launch/terminate in Pending:Wait / Terminating:Wait and emits the EventBridge lifecycle-action event | | | `DescribeLifecycleHooks` | ✅ Supported | | | | `DeleteLifecycleHook` | ✅ Supported | Releases any instance parked on the hook | | | `CompleteLifecycleAction` | ✅ Supported | CONTINUE moves the instance on; ABANDON terminates it | | | `RecordLifecycleActionHeartbeat` | ✅ Supported | Extends the hook's heartbeat window | | | `CreateOrUpdateTags` | ✅ Supported | PropagateAtLaunch tags are applied to launched EC2 instances | | | `DeleteTags` | ✅ Supported | | | | `DescribeTags` | ✅ Supported | Filters: auto-scaling-group, key, propagate-at-launch, value; an unimplemented filter name is refused, not ignored | | | `DescribeAutoScalingInstances` | ✅ Supported | Reports the real instance set the reconciler owns | | | `DescribeScalingActivities` | ✅ Supported | One activity per launch and termination, with AWS's StatusCode and Cause wording | | | `SetInstanceHealth` | ✅ Supported | Unhealthy instances are terminated and replaced by the reconciler | | | `SetInstanceProtection` | ✅ Supported | Protected instances are excluded from scale-in | | ## Related - [Auto Scaling](/docs/services/autoscaling/index.md) — quick start, what works, and the differences from AWS - [All service pages](/docs/services/index.md)
