Question
A company runs a business application on more than 300 Linux-based instances. Each instance has the AWS Systems Manager Agent (SSM Agent) installed. The company expects the number of instances to grow in the future. All business application instances have the same user-defined tag. A CloudOps engineer wants to run a command on all the business application instances to download and install a package from a private repository. To avoid overwhelming the repository, the CloudOps engineer wants to ensure that no more than 30 downloads occur at one time. Which solution will meet this requirement in the MOST operationally efficient way?
Options
- AUse a secondary tag to create 10 batches of 30 instances each. Use a Systems Manager Run
- BUse an AWS Lambda function to automatically run a Systems Manager Run Command document
- CUse a Systems Manager Run Command document to download and install the package. Use rate
- DUse a parallel workflow state in AWS Step Functions to automatically run a Systems Manager

Explanation
AWS Systems Manager Run Command supports rate control, where you can set max concurrency (e.g., 30) and target instances by tag. This lets you run the command on all tagged instances while automatically limiting concurrent executions to 30, avoiding repository overload and scaling cleanly as the number of instances grows, without extra scripting or manual batching.
