IAM user creation and deletion are AWS API management events. CloudTrail records management events such as IAM CreateUser and DeleteUser API calls. EventBridge can match these CloudTrail events with an event pattern and route the matching events to an Amazon SNS topic. Subscribing the company’s email address to the SNS topic provides the required email notification. Amazon Inspector is for vulnerability and exposure findings, not IAM account-change monitoring. GuardDuty can detect suspicious IAM behavior, but it is not the correct service for deterministic notifications every time a user is created or deleted. Amazon Macie is focused on sensitive data discovery and data security findings in services such as Amazon S3, not IAM lifecycle events.

AWS Control Tower provides automatic account governance, centralized logging, CloudTrail aggregation, and integrates directly with AWS Security Hub, which evaluates compliance against FSBP standards. This is the lowest operational overhead AWS-native solution.

For workloads where tasks are independent and can be processed in parallel, and where minimizing management overhead is a priority, a serverless architecture using AWS Lambda is ideal.

AWS Lambda allows you to run code without provisioning or managing servers. It automatically scales your application by running code in response to each trigger.

Parallel Processing: Lambda functions can process multiple tasks concurrently, making it suitable for parallel workloads.

Automatic Scaling: Lambda automatically scales by running code in response to each event, scaling precisely with the size of the workload.

Minimal Management Overhead: With Lambda, there ' s no need to manage the underlying infrastructure, reducing operational complexity.Wikipedia
