AWS SNS + EventBridge

Daily Goal – AWS App Services Challenge Labs

Challenge Lab #1 – Configure an Amazon EventBridge Rule That Triggers an Action

Scenario:

In this Challenge Lab, I will configure an Amazon EventBridge rule that will send an email when an Amazon Elastic Cloud Compute (Amazon EC2) instance shuts down. First, I will verify that the EC2 instance is running, and then I will subscribe to an Amazon Simple Notification Service (Amazon SNS) topic. Next, I will create an Amazon EventBridge rule to monitor the status of the EC2 instance and generate a notification when the instance is stopped. Finally, I will simulate a failure of the EC2 instance, and then I will verify that you received an email notification.

  • Verify that the WebServer EC2 instance is running.
  • Subscribe to the CWAlarm SNS topic.
  • Create an EventBridge rule to monitor the status of the WebServer EC2 instance.
  • Test the EventBridge rule.

Challenge Lab #2 – Configure an Amazon EventBridge Rule that Sends an Automated Email by Using the Simple Notification Service (SNS)

Scenario:

I am a systems operations specialist responsible for an Amazon Web Services (AWS) environment. I need to monitor an Amazon Elastic Compute Cloud (Amazon EC2) instance and generate an email if the instance is stopped. First, I will create a new Amazon Simple Notification Service (Amazon SNS) topic, and then I will create an email subscription. Next, I will create an Amazon EventBridge rule to monitor my EC2 instance for state changes. Finally, I will stop the EC2 instance, and then I will verify that I received an email when the state changed.

  • Created an SNS topic.
  • Created an email subscription to the topic.
  • Created an EventBridge rule that is invoked when an EC2 instance is stopped and that uses an SNS topic as a target.
  • Tested the EventBridge rule by stopping an instance.
