QuestionQ36

Deployment, Provisioning, and Automation

A company operates a business application across more than 300 Linux-based instances. AWS Systems Manager Agent (SSM Agent) is installed on every instance. The company anticipates that the instance count will increase in the future. All business-application instances share the same user-defined tag.

A CloudOps engineer needs to run a command on every business-application instance to download and install a package from a private repository. To prevent overloading the repository, the CloudOps engineer must ensure that no more than 30 downloads happen at the same time.

Which solution meets this requirement in the MOST operationally efficient manner?

Explanation

Systems Manager Run Command can target a fleet of managed nodes by tag and use rate controls. Setting the Run Command concurrency (MaxConcurrency) to the absolute value 30 allows no more than 30 targeted instances to execute the command simultaneously, while tag-based targeting continues to scale as matching instances are added.
