You can now use Change Calendar to prevent desired-state configuration updates made using State Manager. Change Calendar and State Manager are both capabilities of AWS Systems Manager. With Change Calendar, you can schedule calendar events to control when changes can be made to your AWS resources. You can use State Manager to define, enforce, and report on desired state configuration compliance for your infrastructure. With this new integration, you can help ensure that your desired-state configuration updates do not conflict with important business activities, such as sales events or new product launches.

With State Manager, you can establish desired-state policies and specify the schedule on which they should be enforced. Now, you can also ensure the enforcement schedule does not conflict with any blocked events scheduled in Change Calendar. State Manager can also enforce desired-state configuration based on lifecycle events such as an instance launch. With this new feature, you can specify that when these events occur State Manager will wait until it does not conflict with a blocked Change Calendar event to enforce the configuration. For example, if an instance launches during a holiday sale, State Manager can wait until the sale is over to make changes.

Change Calendar is available in all AWS Regions where Systems Manager is offered (excluding the AWS GovCloud (US) Regions and AWS China Regions).

To get started, on the Systems Manager console, choose State Manager from the left navigation pane. To learn more about State Manager and Change Calendar, see the AWS Systems Manager product page and documentation.
