Setting up CloudWatch alarm notifications involves creating encrypted SNS topics, configuring topic policies for CloudWatch access, subscribing endpoints like email or SMS, and linking alarms to notification actions with strict IAM policies and encryption controls.

Yes, you can subscribe email, SMS, and webhook endpoints to encrypted SNS topics for CloudWatch alarms. The configuration validates and tests notification delivery across these channels after linking them to the alarm actions.

Yes, you need specific IAM policies configured on the SNS topics to allow CloudWatch to publish messages. The setup applies strict IAM policies and encryption controls to satisfy security requirements for alarm notifications.

The best way to automate alarm notification setup is using a skill that creates encrypted SNS topics, configures topic policies, subscribes endpoints, links alarms to actions, and validates delivery through tests, ensuring strict security and IAM compliance.

CloudWatch alarms may fail to send notifications if the SNS topic policies do not permit CloudWatch to publish, or if encryption and IAM policies are misconfigured. Validating topic policies and testing delivery across channels resolves this.
