Amazon Systems Manager now supports up to 500 concurrent Automation executions, enabling you to automate operational tasks, such as patching instances on a larger scale. If you enable adaptive higher concurrency, Automation will automatically increase or decrease the concurrency quota based on the scaling requirements. You can enable adaptive higher concurrency from the Automation Preferences tab.

You can use Systems Manager Automation to author runbooks to execute common IT tasks, such as patching or restarting instances, at scale with rate controls. You can now execute these tasks on a large fleet of instances at a higher concurrency. You can also visualize and monitor the number of concurrently running or queued Systems Manager Automation executions using Amazon CloudWatch. You can create a CloudWatch alarm to get notified if the usage exceeds a defined threshold such as 80% of the service quota available for the account.

This feature is available in Amazon Web Services China (Beijing) Region operated by Sinnet and Amazon Web Services China (Ningxia) Region operated by NWCD. For more information about Automation, visit the Amazon Systems Manager product page, documentation and getting started guide.
