Allowing Automation to adapt to your concurrency needs - Amazon Systems Manager
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Allowing Automation to adapt to your concurrency needs

By default, Automation allows you to run up to 100 concurrent automations at a time. Automation also provides an optional setting that you can use to adjust your concurrency automation quota automatically. With this setting, your concurrency automation quota can accommodate up to 500 concurrent automations, depending on available resources.


If your automation calls API operations, adaptively scaling to your targets can result in throttling exceptions. If recurring throttling exceptions occur when running automations with adaptive concurrency turned on, you might have to request quota increases for the API operation if available.

  2. In the navigation pane, choose Automation.

  3. Choose the Preferences tab, and then choose Edit.
