AWS Systems Manager Automation now supports running a single workflow in remote accounts and Regions

By GIXnews

You can use Systems Manager Automation to run a single task across multiple accounts and multiple Regions. With this launch, you can target a single remote resource instead of starting workflows for multiple remote resources using tags or resource groups. For example, you can centrally trigger Amazon Inspector runs across all your accounts in all Regions to discover potential security issues on your AWS resources.
