Description |
| Stack Resources |
You can now embed a stack in template by using the AWS::CloudFormation::Stack resource to specify the template to use
for the embedded stack as well as parameters to pass to the embedded stack. You can also use the Outputs.embeddedoutputname format
to refer to output values from the embedded stack.
For more information,
see AWS::CloudFormation::Stack and
Stack Snippets. |
| Auto Scaling Notifications |
You can now create AWS::AutoScaling::AutoScalingGroup resources that send Amazon SNS notifications when
the specified events take place. You use the NotificationConfiguration property on the AWS::AutoScaling::AutoScalingGroup resource to specify
the SNS topic and the events to report.
For more information,
see AWS::AutoScaling::AutoScalingGroup Type,
Auto Scaling NotificationConfiguration Property
and Auto Scaling Group with Notifications Snippet. |
| Auto Scaling Policies |
You can now create AWS::AutoScaling::ScalingPolicy resources to define Auto Scaling policies that specify whether
to scale an Auto Scaling group up or down and by how much.
You can use them together with CloudWatch alarms to monitor metrics and trigger Auto Scaling policies when defined thresholds are breached.
For more information,
see AWS::AutoScaling::ScalingPolicy and
Auto Scaling Policy Triggered by Amazon CloudWatch Alarm Snippet. |
