Explanation:
Amazon EventBridge (formerly CloudWatch Events) is a serverless event bus that supports scheduled expressions (cron or rate). It can be configured to trigger an SNS topic as a target on a specific schedule. This is highly efficient and serverless, avoiding the overhead of managing EC2 instances or complex Step Function workflows for a simple periodic notification task.
