The SysOps administrator needs to deploy auditing software on all existing and new EC2 instances...

Create a Systems Manager Distributor package that includes the auditing software. Store the package in an Amazon S3 bucket. Create a Systems Manager State Manager association in each Region to install the software package on all managed instances in the company's AWS account.

Load the installer for the auditing software into an Amazon S3 bucket. Connect to every instance by using Systems Manager Fleet Manager Remote Desktop. Download the installer by using the AWS CLI. Run the installer manually.

Create an AWS Lambda function that calls the software installer. Merge the auditing software into the Lambda function by using Lambda layers. Run the Lambda function from each instance by using a scheduled Amazon EventBridge rule.

Create an Amazon EventBridge rule to react to Amazon EC2 RunInstances events. Configure the rule to modify the events to include a step that runs the software installer. Reboot all the instances.
